Foreword

Western Australia Tomorrow is a set of forecasts1 based on trendssince the 1980s. The forecasts represent the best estimate of futurepopulation size if trends in fertility, mortality and migration con-tinue. They use the latest information about changes in trends. Insome cases these have occurred since the 2006 base year.

Trend forecasts are used in a number of ways. One of them is toidentify those futures which we wish to build upon and some thatwe would rather avoid. As a result government has adopted plansand strategies that are expected to change future trends. These in-clude Directions 2031 and Beyond, Pilbara Cities and Supertowns.Each of the plans and strategies has included a forecast of futurepopulation.

The forecasts within these plans and strategies differ from WA To-morrow in a number of ways. In some cases, such as Directions2031, the aggregate forecast has been consistent with WA Tomor-row. The emphasis in this plan is on meeting the requirement tofind room for future population growth while maintaining local en-vironments and valued quality of life. In other cases the forecastsrepresent an aspirational target which is seen as beneficial for thecommunities involved. The emphasis may not be on the forecastbut rather on what changes may be needed to change future pop-ulation. As a result the forecast is about direction and not theultimate size of population.

Future WA Tomorrow forecasts will incorporate the changes achievedthrough these plans and strategies. Sometimes it will be easy toknow how to incorporate the different views of the future. Readerswill need to fully understand what a particular plan or strategy istrying to achieve and make an assessment on the relevance of theplan or strategy.

Population forecasts for Local Authorities 2006 to 2026IntroductionThe WA Tomorrow forecasts for local gov-ernment areas have been developed to pro-vide comprehensive demographic informationabout the age and sex structure of future pop-ulation. This information is required to meeta wide range of demand for a variety of Stategovernment agencies.

The total population forecasts that are pre-sented here are a secondary use (albeit animportant one) of the forecasts. Users whowish to understand changes to the age of thepopulation or to look at what changes are ex-pected for those of particular ages should lookat the other publications (forecast profiles)which have been prepared.

What’s new in these forecastsThese forecasts have been prepared using10,000 slightly different simulations. Thesimulations emulate the variability that isshown in past data. The simulations havebeen broken into bands according to the to-tal population in any given year. There arefive bands each with 2,000 simulations. Themedian value of each band is published to give5 forecasts for each LGA.

Band A contains the lowest forecast simula-tions. Band E has the highest simulations.The forecast for Band C is also the medianvalue for all the forecasts as it is the middleband. The Band C forecast is comparablewith the previous WA Tomorrow (2005) pub-lication.

The main part of this publication is the pro-vision of total population data for each localauthority. Bands A, C and E are provided.Two charts accompany the table. The first isa visualisation of the table and includes his-torical data to give perspective to the fore-casts. The second chart shows the change inage profiles between 2006 and 2026. In mostcases the changes are less dramatic than pre-vious forecasts. This is due to the more real-istic migration modelling.

Limits of population forecastingIf we lived in a world that did not changethere would be little need for forecasts.Nathan Keyfitz2 notes that for us to act ina way that is useful we need to have at leastsome idea of what the future holds. Somepeople suggest that the world is so erraticthat we cannot forecast with any degree ofcertainty. This echoes the work of DavidHume.3 He concluded that we could not con-ceive the future without understanding howevents/things happen. This work resonatesin contemporary statements that the worldis ever changing and we cannot use the pastas a guide to the future. The suggestion isthat we must include everything to be ableto forecast.

In contrast Frederick L. Will4 in his paper“Will the future be like the past? ” argueswhen we find patterns that are so consistentthat we can always be sure of them. He con-cludes that even in the future we can still besure of them. As a result, forecasters searchfor these regular patterns. Weather forecast-ers have found regular events can give us anidea of future weather. They are not perfectbut they are good enough to use them daily.A forecast of rain will see many of us pickup our umbrellas. Airlines use the forecast toavoid bad weather. The forecasts have limi-tations, but this does not stop us from usingthem.

Using modelsForecasters use models to make their fore-cast. Therefore, to understand the forecastswe need to understand modelling. One of themost basic models that we use is the sim-ple average. We use it to make life under-standable. Our problems begin when we oversimplify. If we are not careful, we begin todescribe the average person as half man /half woman. This is patently incorrect asthe number of people who actually have suchmedical issues is very small. When you lookeven more deeply you find that nature ac-

tually produces more males than females soeven the half is not that accurate. The realmodel is that about half the population is fe-male and half is male.

Models are a way of representing the worldin a simplified manner. We know that thesemodels can never be exact. The engineer usesphysical models in wind tunnels to test outcomplex mathematical equations. This showsthey can still be useful. The key to their use-fulness is their relevance. George Box high-lighted this in his 1971 presidential addressto the American Statistics Conference. Hecalled on statisticians to use models that re-flect reality. He said this was more impor-tant than using sophisticated modelling tech-niques. The cohort component model used inthese forecasts meets this requirement.

Modelling choices for the fore-casterModellers need to build models that are re-alistic. They should not reinvent the world.It is said that Albert Einstein suggested thatmodels should be as simple as possible, butnot so simple that they ignore essential as-pects of reality.

To forecast the total population of WesternAustralia we could simply extend the pasttrend. This technique has been widely usedand in many cases is good enough. However,it has been shown that simple, or complex,extrapolation is not a good choice for fore-casting the age and sex of a population.

The reason for this is that age, like the fore-cast, changes with time. This means that theage and sex of a past population influencesthe future population. A person aged 10 atthe beginning of a forecast will be aged 30 bythe end of a 20-year forecast. Therefore, thesimplest way to forecast their age the follow-ing year is to add 1 year each year.

This deceptively simple calculation forms thebedrock of demographic accounting. Wemake the component assumptions using past

rates of fertility, mortality and migration.This model is called a cohort componentmodel. The model takes the existing popu-lation as a base. For each year of the forecastbirths are added to the existing population asare new migrants, next deaths and outwardmigrants are removed. There is no need forextrapolation.

Past trends are never perfectly stable. Ratesvary from year to year and we only get arough guide for the future. This forecast uses10,000 simulations to show the same erraticnature as seen in the past. Using this num-ber of simulations allows us to get some ideaof future uncertainty. In some ways, it is likestating, “There is a possibility of rain, late inthe afternoon” or “we are not sure, but oftenit happens.”

So how does it all work?The population is aged one year. This meansthere are no babies left, as all children are nowaged one or older. Therefore, we calculatehow many new babies will be born. Researchshows that the age of a woman is an impor-tant indicator of when she will have a baby.Biological, social and legal restriction meansthat women are generally aged between 15and 50. The number of women in this agegroup determines how many babies will beborn. This in turn suggests that the numberof women aged 14 to 49 in the previous yearwill form the core of the women who will fi-nally have babies. To a lesser degree we cansay that women aged between 5 and 40 tenyears previously will also be a good indicatorof the number of potential mothers in thatyear.

This is important, as we know that previousbaby booms have resulted in boom echoes.This is because each boom group reaches theage of motherhood at the same time. That isfemale babies from a baby boom grow up andtend to have their babies at the same time.This is true in many different countries.

Just as there is inevitability about birth beinga requirement to enter the population, mor-tality plays a role in leaving. The 17th cen-tury saw these regularities5 and we still seethem today. Ever since, demographers andactuaries have been working at ways of calcu-lating how long we can expect to live . Insur-ance companies use these regularities to cal-culate life insurance premiums, so that theycan ensure a profit. The techniques work wellas insurance companies continue to offer lifeinsurance.

The pattern of mortality is equally wellknown. Very young children are at theirweakest just after they are born. It is heart-ening to know that as young children age theyare less likely to die. However as they be-gin to reach teenage years the risk taking,particularly by boys, takes its inevitable toll.This keeps rising until maturity appears totake hold and the death rate stabilises. Fora while, the death rate does not vary a lot.As we reach our 50s, as the adverts asking usto see the doctor testify, medical conditionsstart to take their toll and the rates start torise as we age.

This pattern is resistant to all but the mostdramatic events such as plague, epidemicsand war. The regularities of births anddeaths mean that in the short term forecastsare accurate. The model passes the test setby George Box, in that they model a reality.However, they form only part of the story.

While each of us has only one birth and onedeath, we may choose to move where we like,as often as we like. This is probably the mostdifficult demographic component to forecast.

Like mortality, migration has been studied fora long time. In 1885 E.G. Ravenstein wroteabout“The Laws of Migration.”Much of whathe wrote is still relevant today. There is a vastamount of research on why we migrate. How-ever, we cannot model the movements with asingle theory. As with mortality and fertility,migration shares a relationship with age.

The story of migration is familiar to many ofus. When we are children, we have no controlover where we live, so for the moment we willskip the early years. However, by the timewe reach our teenage years there are obviouspatterns that emerge. For some a move to aschool is required if we wish to get the edu-cation we want. More likely, it is attendanceat a tertiary institution where there appearto be limited opportunities in regional WA.

From our later teenage years, we start enter-ing the workforce. We now have the moneyto make a move. The reason for moving mayinclude setting up home or finding a job inanother town. There are many varied rea-sons, but the commonality is that it is timeto leave home. This tends to reach a peakbetween the ages of 15 and 23, when this agegroup is more mobile than they will be at anyother time in their life.

From this peak, the rate of migration be-gins to fall. However, it is after these agesthat the pattern for children becomes evi-dent. Migration is high when the childrenare young. Before school age, there is lessneed to think about their education but wesee that as they commence school the numberof children moving reduces. It seems likelythat the family structure plays a role in de-termining how often families move. Typically,we reach the lowest mobility just before sec-ondary school. It then continues to rise aschildren leave home.

As we age our propensity to move declines.There are two main exceptions to this. Thefirst is associated with life changes made be-fore or for retirement purposes. These typi-cally include looking for places to live wherework is not the major factor. Lastly, for thefirst time in a person’s life there are signif-icant moves made because of health relatedreasons. We might move into an aged carefacility or in other cases to a place where spe-cific medical facilities are available.

These patterns vary from region to region and



it is clear that there are distinct relationshipsin the past migration that relate to age. Ithas been also been shown that the local pat-tern tends to be similar over time. We haveused local migration patterns in these fore-casts. Some places are favoured destinationsfor retirement or work and these patterns re-main stable over time.

UncertaintyThe single forecast in WA Tomorrow (2005)used an average of past trends. The problemis that averages can mask the true picture.This was not obvious to most users who as-sumed the single number forecast had a highlevel of accuracy.

This set of forecasts addresses the unrealisticexpectations of many users. It highlights thelimitations of trend forecasts. It gives an es-timate of how uncertain these forecasts maybe. It gives some advice about how to bestuse the information contained within them.We have seen that past forecasts are useful.They have included most of the future popu-lation change.

Trend forecasts are not a prediction of fu-ture population change. Instead, they iden-tify future pitfalls or opportunities. Planningis on ongoing process that seeks to changepast trends. There are active projects suchas “Directions 2031 and beyond” that seek toenhance many facets of life. There are gov-ernment initiatives to improve the economicperformance of our economy. These forecastsinfluence such projects, which in turn alterfuture population change.

Advice for usersIf you are making big decisions seek profes-sional advice. These trend forecasts are lim-ited to information from the past. Usersshould ensure that they also know aboutprojects attempting to alter future popula-

tion change. Some of the initiatives will bemore successful than others.

However, this does not mean that all newprojects are inherently extra to the fore-casts. There are always new businesses start-ing while others close. Typically there is anover emphasis on the impact that new miningprojects will bring about.

The most difficult task is separating factfrom fiction. The processes involved in ma-jor projects are complex. History shows thatsome projects are quick to evolve while otherscan take a very long time. Commercial confi-dentiality can make it difficult to find the realfacts. Opponents and proponents may pro-vide biased information. Users need to maketheir own decisions on these issues.

If these forecasts are being looked at from aneconomic perspective, some care is required.The trends in these forecasts, particularly formigration, are based on the recent past. Dur-ing this time there has been little negativeeconomic news. Some commentators wouldsuggest that this cannot continue indefinitely.

Nuances that are in the forecastsThere are a number of LGAs where there isinformation specific to that LGA or region.This information is included in the reports.Users should ensure they have found any rel-evant notes. We have adjusted the forecastswhere there is an apparent change in trend.Users should ensure that they are comfortablewith those changes.

Users should read the assumptions and tech-nical notes used in these projections. Themost important assumption is overseas mi-gration into Australia. Many users will notexpect overseas migration to play a big rolein the size of local populations. This cannotbe overstressed.

MethodologyThe population projections are derived usingan accepted model called the cohort compo-nent model. A commentary on the realisticnature of the model is included in “So howdoes it all work?” on page 2.

The model itself is based on a simple demo-graphic equation. Donald Rowland6 puts itsimply as

population growth =

(births - deaths) + (arrivals - departures)

We take the population as of 2006 to be ourstarting point. We then calculate populationgrowth for the next year. Since we are alreadypast 2006 we can use the information that wealready know in our forecast. Thus we have

used the published data on births and deathsas well as overseas arrival and departure in-formation, for the years to 2010.

Additionally we have also used indirect in-formation on new homes, building approvalsand estimates of the population produced bythe ABS using their model. This indirect in-formation has not been taken at face value.Where the trends corroborate each other theyhave been used to adjust past trends. Theadjustments also provided better fits betweenthe births and deaths recorded during the pe-riod of 2006 to 2009 and the forecast birthsand deaths during this period. That is theadjustment that needs to be made to makethe sum of births for each local governmentarea equal to the State total, is reduced oncethe adjustment is made to migration withinWestern Australia.

Local government areas where informationsince 2006 has suggested a stronger rate ofgrowth include Armadale, Busselton, Dard-anup, Kwinana, Mandurah, Murray, Perth,Serpentine-Jarrahdale and Wanneroo. All ofthese areas are likely to have benefited fromthe recent record levels of overseas migrationto Australia. It is less clear how much of thistrend will be temporary and which was partof the long term trend.

In contrast there were areas that did notshow as strong a trend as the past wouldsuggest. These include Gosnells, Joondalup,South Perth, Stirling, Subiaco and Swan.The changes in these areas is not great andthe amount of uncertainty is probably big-ger than the slow down. It seems likely thatthese areas would be affected in the same wayas the areas above in the event that overseasmigration were to substantially slow down.

Both fertility and mortality have been fore-cast using accepted methods. The result isthat life expectancy is expected to continueto grow as it has in the past. Figure 1 showsthe age specific mortality rates used for WA.This can be compared with a similar figure inthe forecast profile publications.

On the other hand the assumptions for fertil-

ity are significantly different from those usedin 2005. Previously the trend had been for de-clining fertility rates. This was a world widephenomena and the recent changes that hadbeen seen were not sufficient to suggest thatthere had been a change in trend. It has nowbecome clear that there has been a change.The age specific fertility rates used for WAare shown in Figure 2.

Figure 3 shows the overall age structure ofmigrants into Western Australia. There isonly a small proportion of interstate migrantscompared with those from overseas. There isa greater proportion of younger people rep-resented in the overseas migration. The ageprofile of interstate migration mirrors the agestructure of Western Australia, hence the flatband.

The most volatile component of populationforecasts for Australia is the assumption onhow many net overseas migrants (NOM)there will be. This is evident in all the fore-casts made in Australia. Figure 4 shows theway in which net overseas migration has beencalculated. This is an important chart as itis this assumption that plays the biggest rolein the size of the final population.

The recent record migration into Australia isnot a repeat of previous booms. Unlike pre-vious booms this boom involved significantnumbers of overseas students coming to Aus-tralia for vocational training. There is signifi-cant evidence that people were attempting touse this program as a way of permanently set-tling in Australia. Changes to this programare likely to reduce this pathway to perma-nent residency in Australia.

At the same time as this boom was happen-ing there were also changes in the way thatnet overseas migration was being measuredin official statistics. It is not clear how thesechanges will influence the way in which NOMcan be used to forecast future residents ofAustralia.



Figure 4: Method used to calculate future net overseas migration in Australia

Hugo7 Canberra, Department of Parliamen-tary Services. pp. 1-83.) noted that therewas a change in settlement patterns fromthose observed after the second world war.This is apparent in the data that is avail-able and the choice was made to exclude therecent (student induced) record boom frompast trends and to forecast the 20 year periodfrom 1984 to 2004 as being the best indica-tive trend for future migration. A 2 year lag

between arrivals and departures provided thebest fit for net migration calculations.

Figure 4 shows that there is a lot more uncer-tainty regarding arrival numbers than thereare for departures. This is because the pastdata shows that people leaving is much morestable. This is not surprising as border con-trol is more focused on who is entering thecountry than on those leaving.



Figure 5: Past levels of net migration into Western Australia and gross domestic product(GDP)

Figure 5 shows past levels of net migrationinto Western Australia. To aid understandinghow net migration can be influenced by eco-nomic conditions the annual rate of change ingross domestic product (more often referredto as GDP) has been plotted. It can be seenthat the peaks prior to 2006 generally re-lated to years with good economic growth. Amore complex analysis shows that commodityprices and other economic factors also play arole. However GDP does seem to be a rea-sonable proxy for good economic times.

The point of this analysis is that the fore-cast is based on a trend of good economicconditions. It is clear that in those yearswhere there were poor economic conditions(red dots) that net migration was substan-tially lower. An overall analysis of these fore-casts would have to conclude that these arebased on future economic growth that is verygood for the western economies.
