Depending on the source, it is estimated that there are between 3 to 5 million farmworkers in the United States.
Two main sources of national data on farmworkers are the Department of Labor National Agricultural Workers Survey and the HRSA Bureau of Primary Health Care Uniform Data System.
National Agricultural Workers Survey (NAWS) By far the most cited national data source on farmworkers is the NAWS. Published by the Department of Labor it collects demographic and employment characteristics of the nation’s hired crop workers. The NAWS is a nationwide random survey that obtains information directly from farmworkers. The most recent NAWS is for the period 2001-2002. The data was obtained through face-to-face interviews with 6,472 crop farmworkers. The report can be obtained: http://www.dol.gov/asp/programs/agworker/naws.htm
Uniform Data System (UDS) The BPHC Uniform Data System is an annual reporting requirement for all BPHC grantees that collects information on the health center operations and patient demographics. Although in the past the UDS has collected limited information on MSFW and their family members, as of 2005 migrant health grantees are required to provide both a universal report as well as separate tables 3 (users by age), 4 (health insurance demographics), 5 (encounters and users ), and 6 (selected diagnosis)for the migrant and seasonal farmworker population. Information on the Uniform Data System and related national reports can be obtained at the BPHC web site at http://www.bphc.hrsa.gov/uds/default.htm
BPHC Migrant Enumeration Profile Provides county estimates of farmworkers based on estimated crop demand for labor for the ten states: Arkansas, Texas, California, Florida, Washington, North Carolina, Louisiana, Maryland, Mississippi, and Oklahoma.
