Other Farm Labor Information Sources
In addition to the NAWS, there are several other Federal sources of agricultural employment and farm labor data:
The U.S. Department of Agriculture's (USDA) Census of Agriculture http://www.agcensus.usda.gov collects data from agricultural employers on the number of workers they hired and their expenditures for hired and contract workers.
The USDA's Farm Labor Survey http://usda.mannlib.cornell.edu/MannUsda/viewDocumentInfo.do?documentID=1063 collects data from farm employers on how many workers they hired, average hourly earnings, and the number of hours worked during the survey reference week.
The USDA's Agricultural Resource Management Survey, Costs and Returns Report (section 26 of the core questionnaire) http://www.nass.usda.gov/Surveys/Guide_to_NASS_Surveys/Ag_Resource_Management/ asks farm employers how much they paid in cash wages to family, hired and contract labor, and their expenditures for custom work.
The Current Population Survey (CPS) http://www.bls.gov/cps/ and the American Community Survey (ACS) https://www.census.gov/acs/www/ are household surveys that ask respondents about their most recent job. Occupation information can be used to identify some types of farm workers, e.g., crop and livestock workers.
