Abstract: Both anecdotal and statistical evidence suggests that American marriage grew more unstable at the beginning of the 20th century. I investigate the causes behind this concurrent increase in marriage rate and in marital disruption rate. Economic theory from Becker (1993) suggests that causes of increased breakups occur either as a result of increased search costs (more bad matches in successive marriage cohorts) or a decrease in the value of marriage relative to outside options. I argue that although the value of singlehood increased in the early 20th century (particularly for working single women) the expected benefit of marriage increased even faster, leading more couples to tie the knot. At the same time, the early age at marriage meant that spouses married with less detailed knowledge about each other, leading to a greater probability of a later disruption.

1. Introduction
The onset of the 20th century was a time of sweeping transformation of American marriage. The
1890s and early 1900s saw the reversal of many demographic and social trends: (i) after almost a
century of increase, the age at marriage peaked around 1900, commencing a sixty-year decline
(Haines, 1996); (ii) age difference between spouses also peaked around the same time, since the
movements in age at marriage were more pronounced for men than for women (Ferrie and Rolf, 2008);
(iii) as a corollary of the turnaround in age at marriage, reduced marital fertility replaced postponement
of marriage as the primary cause of decline in total fertility (Sanderson, 1979: Table 2); (iv) labor
supply of married women started to shift out of the household and the family farm or business into the
outside (“formal”) labor market (Goldin, 1990).
A newly added piece to this picture of transformation is (v) the steep increase in marital disruptions
– especially those which took the form of desertion or separation and never became official divorces in
court – as estimated by Cvrcek (2009). Not only was there an increase in the overall rate but the gap
between disruptions and divorces widened, indicating a declining reliance on legal procedure for
ending marriage among Americans. Divorce statistics therefore understate the extent of marital
instability; the disruption rate shows that the true level was up to twice as high and that it increased
significantly after the turn of the century. What were the causes behind the increase in disruptions?
How does this fit together with the broader picture of a transforming American family?
Most couples promise each other at the altar to stay together “till death do us part”, suggesting that
marriage is entered into with a long-term (even lifetime) horizon in mind. This applies even to
marriages that eventually prove short-lived. The concurrent increase in both the marriage rate and the
disruption rate therefore poses several questions: if one should argue that the marriage rate increased
because gains from marriage increased (relative to singlehood), then why did the marriages break up in
2
greater numbers? Did the expected gains fail to materialize after the wedding? If so, why were early
20th-century couples so myopic as not to foresee this?
The period was a time of expanding opportunities for women – both single and married – which
introduced greater flexibility into how a household may operate.1 This probably increased the expected
gains from marriage on average given that utility is non-decreasing in the size of the choice set. Such
anincrease could account for the rise in marriage rate, provided the gains from marriage grew faster
than the value of being single. At the same time, however, the new options also increased the variance
around the higher expectation, and probably introduced more uncertainty into the search of a lifetime
partner. I argue that the declining age at marriage after 1900 represents a decline in the amount of
intensive search undertaken; i.e., men and women were getting married with less in-depth knowledge
about each other which was the direct cause of the increased variance in marital outcomes. Thus, a
greater proportion of matches produced outcomes that for one of the parties fell below the threat point,
the value of outside option, leading them to leave the marriage.
An alternative hypothesis (not explored here) would posit that the concurrent increase in both
marriage rate and the divorce rate was due to the decline in transition costs between the marital states.
It is not clear how much these costs changed in the period in question2, nor is it clear how important
they were in couples’ decision-making. After all, these costs are paid once and up-front and they must
be compared with the expected stream of lifetime benefits that would accrue from getting married or
from leaving an unhappy marriage.
1 For example, the employment during singlehood allowed even poor women, who otherwise would have no dowry, to accumulate at least some meager savings before setting up their own household after marriage and starting a family. The slowly growing married women’s employment brought about the possibility of two adult earners in a family.2 It may be argued that the costs of marital disruption actually increased in the first two decades of the 20th century and only later declined. See section 3.

2. Historical overview of marriage and marital disruption
A wide array of evidence points to the 1890s and early 1900s as to a period of change in American
marriage. Figure 1 shows that a gradual post-Civil War decline in marriage rate was reversed right
before the turn of the century and the rate increased, by early 1920s, in fits and starts above 80
marriages per 1000 eligible women.3 Similar pattern is visible in other statistics, such as the indirect
median age at marriage which peaked, according to Fitch and Ruggles (2000: Table 4.1), in 1900 at
26.0 for white men and at 22.1 for white women, and declined for both thereafter. The changing
marriage behavior had a strong cohort component: lifetime-singlehood rate was the highest for the
birth cohort born around 1870 (who would be getting married in the 1890s and early 1900s), reaching
12% for men and 10% for women (Haines, 1996: Figure 3). Both preceding and subsequent
generations had lower rates of lifetime non-marriage. The beginning of the 20th century was therefore a
time of a renewed interest in marriage, setting a trend that would last until the 1960s (albeit with some
variation during the years of the Great Depression and the Second World War).
In Cvrcek (2008), I argued that the trend reversals in marriage behavior and fertility were a result
of increased bargaining power of single women. Industrial development and technological change
drew a growing proportion of single women into the labor force, increasing their threat points in
negotiation with potential suitors over the specifics of marriage. While at first the higher demands
made these working single women less desirable as potential partners (relative to non-working single
women), as their ranks swelled, the men eventually (around 1900) acquiesced and accepted the new
redistribution of gains from marriage. However, the increase in marital disruptions (i.e. all divorces,
desertions and separations combined) after 1900 may suggest that this new redistribution, agreed prior
to marriage, may have been difficult to enforce ex-post. The disruption rate (also presented in Figure 1)
picked up speed around 1900 and increased much faster than the divorce rate.
3 The marriage rate is very similar when calculated per 1000 eligible men.

The gap, opening up between total disruptions and divorces after 1900, was made up of an
increasing number of unilateral desertions and mutually-agreed separations. In cases of separation and
desertion, a marriage ends ‘in real terms’, with the family ceasing to function as a social and economic
unit, but not in legal terms. Since most such non-legal breakups left no paper trail, it has long been
considered practically impossible to estimate their historical incidence (Plateris, 1973: 15; Price-
Bonham and Balswick, 1980: 966; Igra, 2007: 75). In Cvrcek (2009), their extent is estimated from an
integrated public-use microsample of the 1900, 1910 and 1950 censuses (Ruggles et al., 2008), from
data on the size of individual marriage cohorts (Jacobson, 1959) and from mortality statistics (Haines,
1998; Carter et al., 2006). Figure 2 uses the estimate to provide a cohort measure of the extent of
marital instability, giving the percentage of each marriage cohort that was disrupted during the cohort’s
lifetime. The growing gap between divorces and disruptions after 1890 shows that divorces alone
could not provide a complete picture of marital instability.
The causes behind the increased marital instability were unclear to contemporaries. Yet, although
they did not have any aggregate statistics on the incidence of desertions and separations, the
proliferation of contemporary literature on the topic, penned by social workers, illustrates the growing
awareness of the changing marital landscape (Brandt, 1972; Smith, 1901). They usually cast the causes
of marital disruption in terms of behavioral problems of the husbands (such as alcoholism, short
temper or vagrancy). Modern demographic literature, on the other hand, looks more closely at the
economic, social and demographic factors behind divorce and disruptions. Most studies show that the
risk of marital disruption declines with age at marriage, education, income, duration of marriage and
presence of children in the family (though not necessarily their number); and increases with premarital
childbearing, order of marriage and age gap between spouses (Becker et al., 1977; Rodrigues, Hall and
Fincham, 2006; Faust and McKibben, 1999). Premarital cohabitation is also associated with higher
incidence of subsequent marital break-up although expert opinion is split as to whether this is due to
selection or causation. There is some evidence that high ratio of wife’s to husband’s earnings is more
5
conducive to marital disruption but Rodrigues et al. (2006: 90) claim that “the findings in this area
have been mixed”.
By way of motivation, Table 1 presents a simple regression of cohort and period disruption rates on
the marriage rate, the cyclical component of GDP per capita, a measure of urbanization, the singulate
mean age at marriage (SMAM) of husbands and the SMAM difference between wives and husbands in
the year of marriage of each cohort.4 The purpose of the regression is to establish certain broad
correlations.5 Cohort disruption rate is positively correlated with the marriage rate and for every extra
marriage per 1000 marriageable women, the cohort disruption rate increases by about 0.73 percentage
points. This result makes the marriage rate the most powerful explanatory variable in this regression
specification. When marriage rate increases, the resulting marriage cohort contains greater proportion
of ‘bad matches’ which eventually break up, increasing the disruption rate. In contrast to that, the
cyclical component of GDP does not have any meaningful effect; moreover, the coefficient is clearly
statistically insignificant. However, this is because the marriage rate and GDP per capita are highly
correlated – so it is reasonable to hypothesize that the state of the economy affects who gets married
and who does not.6 Through this – indirectly – the business cycle influences the marital stability of
various cohorts. The rate of urbanization has a strong and positive effect on the cohort disruption rate
and the two specifications show that the effect is not dependent on the choice of a threshold of
‘urbanity’. The urbanization variable clearly captures many of the modernizing trends then in
operation: industrialization, migration, population growth in general as well as growth of urban
population in particular. The signs are what one would expect for the two demographic variables, with
lower age at marriage (for which SMAM is a proxy) resulting in slightly lower disruption rate and
4 Singulate mean age at marriage (SMAM) is a demographic concept similar to life expectancy: they both measure the expected time to a life event. But while life expectancy measures years of life remaining to death, SMAM measures years of life remaining to marriage. Both are calculated using cross-sectional patterns (of death and marriage, respectively) and applying them to a cohort across the cohort’s hypothetical lifetime.5 Given that the dependent variable is by definition constrained to fall between 0 and 100, a truncated regression was also estimated but the coefficient or standard errors are not substantially different from those presented in Table 1.6 This is also born out by column (v) which shows that the marriage rate responds strongly to the business cycle.

higher gap between husbands and wives leading to a higher rate. However, of these two variables only
the age gap has an effect of any practical importance and both coefficients are estimated with large
standard errors. The period disruption rate (in columns (iii) and (iv)) is somewhat sensitive to the
business cycle and the positive coefficient implies that when marriages disrupt, they do so more under
auspicious economic conditions, i.e. in times of boom. Partly, this is probably due to the effect of the
economy on the utility from marriage but to some extent, this coefficient is capturing the effect of
economic fluctuations on early marriages which affects the cohort rate and with which the period rate
is highly correlated.7
I interpret these broad correlations as preliminary evidence that the future success or failure of a
marriage is to a considerable degree determined on the marriage market. Although the period
disruption rate varies from year to year, suggesting ample room for specific period effects, most of this
variation comes from disruption of young marriages from recent marriage cohorts which is closely
correlated with the marriage rate, i.e. with the situation on the marriage market at the time when a
marriage cohort is formed. Period effects (i.e. a shock to all marriages across all durations in one
particular point in time) are likely secondary to the cohort effect of the conditions on the marriage
market. In plainer words, finding the right lifetime partner seems more important for the success of
marriage than being able to make ends meet in any particular year of marriage.
3. Theoretical considerations
If both marriage formation and marriage disruption had their root in the changing dynamics of the
marriage market, what can be said about this market operates in general? Becker et al. (1977)
distinguish between extensive and intensive search costs, corresponding to how difficult it is to meet
new people and how hard it is to get to know them well. Extensive search costs will be high if it is
difficult to encounter the opposite sex (for example, due to high segregation by gender). They will also
7 Conditional on divorcing at some point in life, 50% of couples separate (i.e. stop living with each other) within the first five years of marriage, hence the high correlation.
7
be high if a person looks for a spouse with a particular trait that is rare in a population, such as finding
a high-earner in a poor neighborhood. In such instances, a person will be willing to accept a match
with a suitor farther away from the “optimal” trait, entering a marriage with a lower expected benefit.
The extensive search cost therefore affects the mean (the expectation) of gains from marriage.
Intensive search costs, on the other hand, affect the variance of potential marriage outcome (as well
as the mean). Even a partner who is currently a high earner may not turn out to be such in the future.
For example, marrying a medical student may carry the prospect of potentially high earnings but, of
course, the actual outcome will depend on how good or bad a doctor the medical student turns out to be
eventually. While it may be easy to meet and become acquainted many medical students in a brief
period of time (low extensive search costs), it will likely be harder to establish how well remunerated
they will eventually be (high intensive search costs). Perhaps even more relevant for marriage is
physical attraction: finding a person with attractive features is a matter of extensive search because
physical features (such as face, height and bodily constitution) are relatively easy to observe. However,
finding out whether a couple is mutually sexually compatible is not immediately observable and is a
matter of intensive search. The costs of such search (along both the extensive and the intensive margin)
change through time, for example as clothing becomes more revealing and the costs associated with
premarital sex (risk of pregnancy, STDs or loss of reputation etc.) decline.
The reason why both extensive and intensive search is important is that the quality of a match is an
‘input’ in the overall utility from marriage. This in turn determines how valuable a marriage is relative
to the outside options. There are of course other factors that affect how welfare inside and outside
marriage compares, such as the presence and number of children in a family (and other such examples
of what Becker (1993) calls marital specific capital) or the situation on the remarriage market and
opportunities for financial independence outside marriage (such as ease of finding employment for
housewives) etc. which affect the outside options of each party in marriage. Changing outside options
obviously affect even surviving marriages because they act as threat points in intra-marital bargaining
8
(Stevenson and Wolfers, 2006) but as long as the sum of outside options of the two spouses is lower
than the overall gain generated inside marriage, there exists an allocation of the gains such that both
spouses find it preferable to stay married.8 Otherwise, the marriage breaks down.
Existing theory on intra-marital bargaining and marital discord, as expounded in Becker (1993),
Becker et al. (1977), McElroy and Horney (1981) and Pollak and Lundberg (1993), attribute marital
disruption to one of three causes: 1. an increase in search costs which introduces more uncertainty into
finding a spouse and produces more bad matches among the newly married 2. an improvement in
outside options of married people which increases their incentives to leave their marriage, and 3.
(which is a flip side of 2.) the gains from marriage decline for one of the parties. Note that all the
socio-economic and demographic factors mentioned in previous section can be easily recast in terms of
these three underlying causes. For example, wide age gap or large disparity in education between
spouses are a sign of a suboptimal spouse match while high earnings potential of the wife implies her
good outside options which make leaving an unsatisfactory union relatively easier and more appealing.
How do these theoretical considerations bear on the question at hand? In the early 20th century,
both marriage and disruption were on the rise. The increase in marriage rate suggests that the expected
gains from marriage relative to alternatives must have increased. Such a development is possible if the
extensive search costs fall and men and women are better able to find a partner who is close to their
“ideal”. Alternatively, a change in technology may make it easier to generate gains from marriage,
increasing the returns on investment in marital-specific capital.
The increase in disruption rate is consistent with an increase in intensive search costs which
increased the variance of marital outcomes, causing a greater proportion of them falling below the
threshold posed by the outside option of divorce or desertion. Given that a major component of the
intensive search cost is time (or more precisely the duration of a relationship before marriage), some
8 Of course, this argument relies on the assumption of zero (or low) bargaining costs, the empirical validity of which is open to question.
9
evidence of the increased intensive search cost comes from the fact that the age at marriage declined
after 1900. Koller (1951: Table 2) shows that the number of suitors seriously considered by women as
potential husbands did not change significantly between the 1890s and the 1940s, with 80-90% of
women across all generations in his sample claiming to have seriously considered no more than two
men. Moreover, in each of the three generations he studies, the women’s first date with their future
husband occurred at about the same age (19). If age at marriage was declining at the same time, this
implies that less time was spent on dating, i.e. on the intensive search which is consistent with the
hypothesized increase in the cost of such search.9
In short, the hypothesis of falling extensive search costs, rising expected gains from marriage, and
increasing intensive search costs can readily explain the stylized historical facts of increasing marriage
rate, decreasing age at marriage and increasing disruption rate.
These trends could also be explained in terms of declining transition costs into and out of marriage.
If both the switch from singlehood into marriage and from marriage into marital disruption became
cheaper, then simple economic theory will imply that more of both should take place, ceteris paribus.10
The transition into marriage involves not just the costs of wedding but also the costs associated with
setting up a new household and the change in daily routine. The costs associated with the onset of
childbearing may also be included in this category since for many young couples the beginning of
married life coincided with starting a family. Although a precise measurement is difficult, it is possible
to infer that such transition costs may have declined, considering the concurrent decline in the rate of
lifetime singlehood among the cohorts born after 1870.11 The transition out of marriage involves the
9 A decline in age at marriage may also reflect a greater frequency of dating: if that was the case, then of course, short duration from first date to marriage would not represent a decline in intensive search. However, with the exception of a (small) increase in pre-marital sex, I am not aware of any evidence that the dating practice of the early century grew any more intensive. Moreover, some aspects of a prospective partner’s personality, such as one’s susceptibility to alcoholism, may just require time, regardless of how often the partners date. 10 In fact, the two may be seen as complements: if it becomes cheaper to ‘undo’ an unhappy marriage then more marriages may take place because the risk of a lifetime of unhappiness is now lower.11 See section 2 and Haines (1996) for estimates of the rates of lifetime singlehood. However, even at its highest, this rate reached about 12%, meaning that even in the least pro-marriage cohort, about 88% of men and women still tied the knot.

costs of divorce or desertion (or separation). Desertion was very ‘cheap’ technically and with the
ongoing advances in transportation technology was getting cheaper by the day (Carter et al. 2006: Df
955). But it involved abandoning one’s children and all property.12 Given that the long term trend was
one of rising living standards and rising real wage (even for unskilled labor), one may argue that
abandoning everything by desertion was becoming more and more costly, ceteris paribus.13 Moreover,
if a deserter wished to remarry, he or she also faced the possible prosecution for bigamy.14 Unlike
desertion, divorce did not entail forsaking all of one’s possessions but it was more costly in terms of
money, time and reputation. These costs probably increased during the late 19th and early 20th century,
as the predominant trend was one towards restricting divorce laws (Amato and Irving, 2006: 46). It
was only after the First World War that this push for strictness gave way to gradual and slow
liberalization. The available anecdotal evidence on changes in transition costs thus points in the
opposite direction than the theoretical framework behind this alternative explanation would require.
In addition, the transition-costs explanation requires not only that the transition costs be falling but
also that the decline be sufficiently large to actually matter – which is not a foregone conclusion,
especially for transition into marriage. Perhaps if there were binding credit constraints, the high
transition costs may exert considerable influence but given that 90% of all men and women get married
at some point in time (usually before they were 35) and that a large portion of the transition costs is
non-monetary (e.g. loss of leisure, loss of comfort etc.) such constraints must have been of only limited
importance.
Another alternative could be that successive marriage cohorts experienced ever greater negative
shocks to their gains from marriage (or positive to their outside options) and therefore disrupted in
12 It is perhaps no coincidence that this form of ending a marriage was more prevalent among the poorer strata, so much so that it was often referred to as “poor man’s divorce” (Eubank, 1916).13 It is true, however, that some deserters cashed in as many assets as they could before deserting. Porter Benson (2007: 55) cites a case from the interwar period where a deserting husband “sold bedding, clothing and anything that could bring any money – and left sixty cents on the table”.14 On the other hand, Brockelbank (1969) argues that since family law is in the purview of states, crossing the state line provided a deserter with a considerable degree of protection against potential legal troubles because each state guarded its autonomy in such matters with great jealousy.
11
greater numbers although it is unclear how such persistent shocks would be consistent with the rising
marriage rate. Presumably, sooner or later, men and women would incorporate in their expectations of
marital gains the greater probability of a negative shock and adjust their marital behavior accordingly.
Which mechanism was at work, whether the search-cost or the transition-cost, is not a priori a
question of clear-cut either-or. It is possible that both had some influence although for reasons
explained above, the transition-costs explanation is perhaps less likely of the two. The following
empirical analysis therefore concentrates on the search-costs explanation.
4. Measures of the marriage market
In my empirical analysis I use 1% samples of the 1880, 1900, 1910 and 1920 censuses (Ruggles et
al., 2008). Of all the characteristics that people match on when looking for potential spouses, only the
most obvious are likely to be found in any dataset: race, age, broad level of education, ethnicity. The
more subtle aspects of a match such as opinions about parenting, handling of finances or sexual
compatibility are often hard to gauge even for the partners themselves and even after several years of
relationship, so any information about these from any relevant-sized sample (especially one dating
back to early 1900s) is plainly unavailable. And so while extensive search costs could potentially be
estimated (see below), the best an empirical analysis can hope for in terms of the intensive search costs
is to simply look at how much intensive search was actually undertaken. Ceteris paribus, if the
intensive search became more costly, individuals would search less and some might be discouraged
from marriage altogether. I therefore use a person’s age as the variable that captures the changes in
intensive search: if less of the intensive search was undertaken, then it should show up in lower age at
marriage, other things held equal.
In measuring the extensive search costs, I assume that men and women match on several readily
observable characteristics: race, nativity, literacy (the only available indicator of education until the
1940 census) and age. For the first three, I assume people wish to match perfectly: e.g. a black man
12
wants a black women, a literate woman seeks a literate man, etc. With age, men usually desire younger
wives and women older husbands and both genders seek partners over a range of ages. So, for a man of
certain race, nativity, literacy and age, I define his marriage market to consist of women who are of the
same race, nativity and literacy, not older than him and no more than ten years his juniors; and of men
who are similar to him in that they compete for the same women that he is searching for. Similarly, for
a woman of a certain race, nativity, literacy and age, the marriage market consists of men who are like
her in the first three aspects, not younger and no more than ten years older than her; and of other
women who seek to match with such men. This way, each person’s marriage market includes both the
competitors and the potential spouses. Only rarely, however, does one’s search for a partner
encompass the whole country; more realistically, the marriage market is relatively local and so I limit
it to the size of a county. The assumptions about how well men and women wish to match reflect
actual historical experience. Tables 2-4 show that a vast majority of American couples matched on the
three characteristics of race, nativity and literacy. Moreover, in 75-80% of existing marriages in 1900,
it holds that 0 ≤ agehusband – agewife ≤ 10.15
To characterize each person’s marriage market, I construct three variables: trait, sex ratio and slfp.
The variable trait is an indicator of the rarity of a given trait: it is computed as the proportion of all
suitable matches in the adult population of the county. The greater the value of trait, the greater are the
chances of encountering a suitable match in daily intercourse, all else equal. The concept behind this
variable is taken directly from Becker et al. (1977) who argue that matching on a rarer trait constitutes
a higher extensive search cost. Mathematically,

15 The age at marriage declined after 1900 for both men and women but the decline was faster for men. Therefore, the post-1900 marriage cohorts showed ever greater degree of age homogamy and so the 1900 statistic can be viewed as a lower bound.
13
where Mi represents the number of suitable men in the county who are i years older than the relevant
woman; W-i represents the number of suitable women who are i years younger than the relevant man,
and Pop stands for the total adult population of the county. Tables 5 and 6 provide a summary of how
this variable changed between 1880 and 1930. The mean is relatively stable across decades although
for both men and women, it declines between 1880 and 1900 and increases afterwards. At the same
time, the standard deviation around the mean declined from 1880 to 1930, suggesting that individuals
faced increasingly more similar marriage markets across the five decades. Table 6 shows that this
compressing trends was not an effect of changing age composition. The median woman aged 22 lived
in a county where acceptable marriage partners of the same race, literacy, nativity and age (22 – 32
years) represented about 8.9 – 9.5% of the total county adult population.16 At the upper extreme, the
proportion could reach one seventh (the 90th percentile in 1880 and 1900), at the opposite end of the
distribution, such men made up less than 2% of the county’s population. For men, the ratio is slightly
higher (median ranges from 0.118 to 0.105). In any given year, the trait is strictly decreasing in age for
women; it increases for men until about age 26 and then starts to decline.17 Across decades, the
variable falls for men, particularly at the upper tail of the distribution. As Table 5 indicated, in Table 6,
too, the distribution of women’s (and to some extent men’s) trait is compressing through time, with
lower percentiles increasing, higher percentiles falling and the median staying relatively stable.
Of course, as a measure of rarity, trait is only one component of the extensive search cost. The
mere presence of potential suitable matches in a population is not the same as being able to meet them.
For example, in sparsely populated areas or in areas that lack the necessary infrastructure that
facilitates such encounters (e.g. entertainment venues or outlets with personal ads) the same value of
trait will be associated with higher extensive search costs and lower probability of being married than
16 In Tables 6 and 7, I chose the age 22 for women and 26 for men because this was roughly the age when about 50% of women and men would be single and 50% already have a marital experience.17 I assume that both men and women can enter the marriage market no sooner than at age sixteen. That is the reason why, for men, the trait increases up to age 26: for younger men, some women who could be their potential matches in terms of the acceptable age gap are still too young to be married.
14
in densely settled areas. Thus, extensive search costs can decline in two ways: either the values of trait
increase from year to year (which, as Tables 5 and 6 suggest, was not universally the case) or the
improving infrastructure makes meeting potential mates easier at any given level of trait. In the latter
case, a decline in extensive search costs would imply a higher probability of getting married across the
board, i.e. at any level of trait.
The remaining variables are designed to capture various aspects of the relative bargaining power of
men and women on the marriage market. The variable sex ratio measures the intensity of competition.
It is defined as a ratio of potential spouses over potential competitors. For example, a woman of certain
traits, aged 22, competes for men aged 22-32. But for men who are at the lower end of this range, she
must compete against women who are of her age and younger than herself while for men who are at
the upper end of the range, her competition will come from women who are her age and older than her.
The sex ratio reflects these shifting overlaps, being defined as

where again Wi and W-i are women (of the same traits in the same county) who are i years older and

By this construction, the ratio captures local variation in the size of birth cohorts and it can realistically
reflect the different situation of, for example, two women who are otherwise the same but are five
years apart in age and who may for that reason face very different marriage markets and command
very different bargaining power with respect to potential suitors – even though they seem to compete
over a pool of men that overlaps to a great degree. Note that the variable is defined as a ratio of the
15
numbers of opposite sex to the numbers of one’s own sex. Thus, both men and women consider higher
ratios to be more favourable.
The distribution of sex ratio across decades is reported in Tables 5 and 7. Table 5 suggests that the
mean sex ratio declined continuously for both men and women. Standard deviation increased between
1880 and 1900 and declined thereafter. Excluding the influence of a changing age composition, Table
7 shows that the median woman, aged 22, faced a ratio of about one throughout the fifty years covered
by the table. As with the trait, the variance of the distribution fell through the years. The sex ratio of
men (at age 26) was falling through the years, especially at the high tail of the distribution. Table 8
shows how trait and sex ratio vary with age and sex in the year 1900. Note that even though the two
variables move together across ages for both men and women, the cross-sectional correlations at each
age are weakly negative and overall correlation is mildly positive for men and weakly negative for
women.
Finally, the variable slfp is the single women’s labor force participation in a given county. This
variable does not vary with the race, nativity, literacy and age of women, it is designed merely as an
indicator of the local labor market opportunities of unwed women. It is a proxy for the outside option
of women, relative to marriage, and therefore another index of relative bargaining power of women. In
a sense, sex ratio captures how strong a woman’s position is relative to other women while slfp stands
in for her bargaining power relative to men (and vice versa for men).
The variables have their share of shortcomings. The variable trait ignores many aspects on which
men and women may match, such as social status and earning power. The sex ratio implicitly imposes
identical preferences on all men and women regarding the desired age difference between spouses. All
three variables ignore any migration, taking simply those individuals recorded in the census at a
particular place as being or having been participants in the local marriage market.
The variables are calculated from all men and women regardless of their current marital status. In
my analysis which seeks to get at marriage formation, I naturally concentrate on young men and
16
women who, even if they are married as of the time of census, must have married fairly recently and so
the ratios and proportions calculated even with their inclusion should to some degree reflect what the
marriage market had been when they were actually choosing their partners.
5. Regression results
I analyze the effect of extensive and intensive search on marriage formation within the framework
of a logit model where the dependent variable is 0 if a person is never married/single and 1 otherwise
(i.e. ever married). The main explanatory variables are individual age, sex ratio, trait and slfp. As
further individual characteristics I add dummy variables for race and literacy. Fixed effects for
individual states are also included. The size of township a person resides in, a categorical variable, is
also included, controlling for the effect of urban environment. The estimation is limited to women
under age 26 and men under age 31: this way the models are estimated from data on those men and
women who either still are on the marriage market or have been there recently.18
The coefficients and mean marginal effects of the relevant independent variables are reported in
Tables 9 and 10. Generally speaking, the marginal effects have the expected signs: the probability of
marriage increases in age, in sex ratio (although the marginal effect is relatively small) and in trait.
Single women’s labor force participation has a negative effect on probability of marriage which is also
understandable: if a single woman’s employment increases the option value of remaining single
(relative to being married), then the negative effect can be expected.19 The only exception is the
coefficient on slfp in the 1930 model for men but the marginal effect is relatively small and the
18 Extending the regression to men and women of all ages produces considerably different coefficients with many of the signs flipping. This is likely due to the fact that older age groups contain, for example, many widows who are classified as ever-married (and so their dependent variable is 1) but the measures of their marriage market indicate highly unfavourable sex ratio and trait values, given the differential mortality between men and women.19 The prevailing practice of a vast majority of women at that time was to quit the labor force upon marriage. The period of singlehood was therefore for many women the last time in their life (until widowhood) when they could indulge in own consumption, independent of considerations what effect such spending would have on consumption of other members in the household.
17
coefficient is not statistically significant. Literacy also has a negative effect which probably reflects the
greater opportunities outside marriage of literate singles compared to illiterate ones.
The second aspect to notice is that the coefficients are very precisely estimated. The standard errors
are low and consistently so across decades and both for men and women. The marginal effects are also
structurally quite stable from one decade to the next. This suggests that the variables are capturing
some of the underlying mechanisms of the marriage market of the time.
The marginal effects of sex ratio are generally small across decades and genders and suggest that
relatively little of the changes in marriage behavior can be attributed to this aspect of the marriage
market. Even large move in the sex ratio would not change the imputed probability of being married
by more than 1 to 2 percentage points.
The variables proxying for search (age for intensive and trait for extensive), on the other hand, do
have measurably meaningful effects. For a woman, holding all other variables constant, a move from
trait = 0.02 to trait = 0.15 (values which roughly correspond to the 10th and 90th percentiles of trait in
1900 in Table 6) increases the imputed probability of being ever married by about 9.8 percentage
points in 1880 and about 4.3 percentage points in 1910. For a man, the same exercise yields an effect
of 17.9 percentage points in 1880 and 24.2 percentage points in 1930. Therefore, trait has the expected
effect cross-sectionally: the higher the value, the higher the probability of marriage. Moreover, for men
at least, this aspect of the marriage market was making an ever bigger difference.
Figures 3 and 4 show how the association between trait and the probability of marriage changed
across decades. The purpose of the exercise is to isolate the effects of changing extensive search costs.
The probabilities depicted in the graphs were imputed holding all other variables constant: they show
how the probability of marriage would change across decades for a person of given fixed
characteristics. For both men and women, this probability increases between 1900 and 1930 for any
level of trait. For men, the shift is gradual while for women, the change occurs primarily between 1900
and 1910. This means that even though there was relatively little movement in trait across decades, the
18
extensive search costs were declining because any given level of rarity of a suitable match was
associated with higher probability of being married.
Men and women differed, however, in terms of where the fall in these search costs had its greatest
impact: the growing slope of the imputed men’s probability from 1900 to 1930 suggests that the gains
were rather modest at low values of trait but significant at the higher end of the relevant interval. For
women, the reverse was true, with the curves getting flatter from decade to decade (with the exception
of the 1920s). In other words, for women, it was getting progressively easier to get married even if
suitable matches were relatively rare in the population. For men, it was getting ever easier to get
married especially when the suitable matches were strongly represented. Overall, the estimation results
are consistent with the hypothesized decline in extensive search costs for both men and women, even
though they occur at different pace and in different portions of the trait distribution.
The intensive search costs must be inferred indirectly from the changing relationship between age
and the probability of being married. Figure 5 and 6 show the imputed probability of being married by
age, holding other variables constant. For women, the marginal effects of age in Table 9 decline first
between 1880 and 1900 and then increase until 1930 but the biggest change occurs between 1900 and
1910: the curves for 1880 and 1900 practically overlap, as do those for 1910, 1920 and 1930. The age
gradient of the probability of being married was therefore getting steeper (at the mean), meaning that
even after controlling for various (explicitly measureable) aspects on the marriage market (such as the
sex ratio and trait), women were getting married younger by about half a year on average. This is
consistent with the hypothesis that they were undertaking less intensive search because it was now
costlier. In fact, the marginal effect of age must be the main source of the increase of the imputed
probability after 1900, because both single women’s labor force participation and literacy have an
increasingly dampening effect on it.
Similar argument can be made for men’s marginal effect of age which also declines first and picks
up after 1900. The movement across decades is not as clear-cut as it is for women but, clearly, from
19
1900 to 1930, the curves shifted significantly such that men reached the same imputed probability of
being married about one year earlier, ceteris paribus. The increase in the probability of being married
was especially marked at the younger ages. Assuming that the age at which men and women entered
the marriage market did not change much, this suggests that less time was spent (on average) learning
about the character of prospective spouse, i.e. less intensive search.
The actual realized age at marriage, as has been mentioned, was declining from 1900 (Fitch and
Ruggles, 2000; Haines, 1996). If Fitch and Ruggles (2000: Table 4.1) argue that men’s indirect median
age at marriage declined by a year and a half between 1900 and 1930, then the present results suggest
that the increase in intensive search costs can account for about two thirds of this change. Similarly,
women’s indirect median age at marriage fell by about 0.6 years over the same time period (most of it
occurring between 1900 and 1910), which corresponds closely to the magnitude of the shift observed
in Figure 6.
Note that, according to the regression results, the rising single women’s labor force participation
acted as a powerful and ever stronger factor against marriage. It is therefore conceivable that the entry
onto the marriage market (particularly by women) was actually occurring at later ages by 1910 and
1920 then in 1900, implying that the actual duration of a pre-marital period of intensive search was in
fact getting short faster than the decline in age at marriage alone would indicate.
Literacy also played a consistently large role in determining the likelihood of tying the knot. For
women, the marginal effect of this binary variable grew more negative between 1880 and 1910 and
then fell back to the 1880 level. A marginal effect of -0.148 in 1910 implies that a literate woman of a
given set of characteristics was 25% less likely to be married than a woman of the same characteristics
but illiterate.

6. Conclusion
The era around the beginning of the 20th century was a time of profound change for American
women and it is not surprising that such changes found their way into marriage and courtship. With the
changing shape of the marriage market came also changes in the way marriage was entered into and
that affected marriage outcomes.
Historical evidence shows that as the 20th century progressed, marriage was becoming ever more
complicated affair. The expectations associated with one’s spouse were becoming more diverse, as
men were increasingly expected to be not only breadwinners but also competent fathers and good
companions. Women, on the other hands, saw their roles change from being almost exclusively
homemakers and mothers to slowly becoming second earners in the family. As these demands
increased, the search for a suitable spouse had to unfold along ever more not so easily observable
dimensions, making the intensive search ever more costly. At the same time, however, the statistical
evidence suggests that it was gradually getting easier to meet prospective partners and to match on the
easily observed characteristics such as race, age and general level of education.
Together, these changes led to the formation of marriage cohorts who had ever higher expectations
of gains in marriage but who also faced greater uncertainty (or variance) as to the eventual outcome.
Thus, American population was concurrently becoming increasingly eager to marry but just as strongly
eager to break up. These trends, commenced in the early decades of the 20th century, are still operating
today.
