MSFW Enumeration Profiles Studies

In 1998, the Bureau of Primary Health Care (BPHC) and the Environmental Protection Agency jointly funded a study to estimate MSFW populations at the county level, and awarded a grant to the National Center for Farmworker Health (NCFH).

NCFH subsequently contracted with Alice C. Larson, Ph.D., to research and develop state estimates for the MSFW population in ten states: Arkansas, California, Florida, Louisiana, Maryland, Mississippi, North Carolina, Oklahoma, and Texas.


Rationale for State Selections

Five states were chosen because they are home to the largest MSFW populations (California, Florida, North Carolina, Texas, and Washington).

The other five states (Arkansas, Louisiana, Maryland, Mississippi, and Oklahoma) were selected because they were states for which minimal data was available, and they appeared to provide a broad sample of MSFW employment environments.


Data Sources

• MSFW numbers are taken from the MSFW Enumeration Profiles Study - Maryland, September 2000.

• MHC and CHC grantee site locations were taken from the BPHC web site (http://ask.hrsa.gov/pc/) in May 2003, and updated by the Office of Primary Care and Rural Health, Maryland Department of Health and Mental Hygiene, in May 2003.

• User data was provided by the Health Resources and Services Administration (HRSA) and BPHC.


MSFW Population Categories

In this analysis, there are four county MSFW population categories:

• 0 to 499

• 500 to 999

• 1,000 to 1,999

• 2,000 and over


Rationale for MSFW Population Categories

The four MSFW population categories were selected based on assumptions about deriving a potential clinic user population number from a target population estimate.

Potential clinics include existing CHC service sites or a new access point. A new access point is a new delivery site for the provision of comprehensive primary and preventive health care services. The two types of new access points are (1) new starts and (2) satellites.

We assume that a target population will produce a 75% clinic user rate and that a clinic site requires 750 to 1,500 users (based on an average ratio of 750 users per PA/NP and 1,500 per physician).


MSFW Population Category 0 - 499

Counties that have an MSFW population from

0 to 499 are assumed to have an MSFW target

population sufficient only to support a user

population that would account for less than

25% of the users of an existing CHC service

site or a new access point.


MSFW Population Category 500 - 999


500 to 999 are assumed to have an MSFW

target population sufficient to support a user

population that would account for 25% to




MSFW Population Category 1,000 – 1,999


1,000 to 1,999 are assumed to have an MSFW

target population sufficient to support a user

population that would account for 50% to




MSFW Population Category Over 2,000

Counties that have an MSFW population

over 2,000 are assumed to have an MSFW

target population sufficient to support a

user population that would justify a new

access point.

MSFW Population

The migrant and seasonal farmworker population is estimated at 9,522. This number includes workers and their dependents.

The largest concentration of farmworkers and their families is located in the southeastern part of the state.

The next slide will present this data as an overlay on the county.

MSFW Population

The next slide will depict the state’s counties organized into four categories, based on the county’s MSFW population.

In addition to the three categories already described, there is a category for counties with an MSFW population below 500.

Analysis Process

Service potential will be evaluated in the following order:

• MHC grantee in county

• CHC grantee in county

• MHC grantee in adjoining county

• CHC grantee in adjoining county


MHC Grantees

There are three Migrant Health

Center grantees in the state. These

grantees provide services at 12 sites

in 8 counties.

Data source: MD OPCRH/DHMH, 5/2003

CHC Grantees

There are twelve Community Health Center grantees in the state. All three of the MHC grantees are also CHC grantees.

The nine additional CHC grantees provide health services at 28 sites in 6 counties.

MHC Grantee Service Coverage

We estimate that over 67% of the

MSFW population lives or works

within 15 miles of the 11 MHC

grantee sites.

MHC Grantee Site Coverage of MSFW Population



MHC Grantee Service Penetration

The seven MHC grantees provided services to 2,009 users1 during 2001, which represents 21% of the estimated statewide MSFW population.

The estimated MSFW population in the counties where the grantees provided health services is 5,3412. The reported users represent over 37% penetration of this population.

CHC Grantee Service to MSFW Population

No CHC grantees report providing services to farmworkers or their families.

We estimate that over 80% of the MSFW population lives or works within 15 miles of an MHC or CHC grantee site.
