Annual data on the labor force, employment, and unemployment in States and substate areas are available from two major sources: the Current Population Survey (CPS) and the Local Area Unemployment Statistics (LAUS) program. The CPS is a sample survey of about 60,000 households nationwide conducted for the U.S. Bureau of Labor Statistics (BLS) by the Census Bureau. The LAUS program is a Federal State cooperative endeavor in which State workforce agencies prepare estimates using concepts, definitions, and estimation procedures prescribed by BLS.
