The Current Population Survey (CPS) is a monthly survey of about 60,000 U.S. households conducted by the United States Census Bureau for the Bureau of Labor Statistics (BLS). The BLS uses the data to publish reports early each month called the Employment Situation. This report provides estimates of the unemployment rate and the numbers of employed and unemployed people in the United States based on the CPS. A readable Employment Situation Summary is provided monthly. Annual estimates include employment and unemployment in large metropolitan areas. Researchers can use some CPS microdata to investigate these or other topics. The survey asks about the employment status of each member of the household 15 years of age or older as of a particular calendar week. Based on responses to questions on work and job search activities, each person 16 years and over in a sample household is classified as employed, unemployed, or not in the labor force. The CPS began in 1940, and responsibility for conducting the CPS was given to the Census Bureau in 1942. In 1994 the CPS was redesigned. CPS is a survey that is: employment-focused, enumerator-conducted, continuous, and cross-sectional. The BLS increased the sample size by 10,000 as of July 2001. The sample represents the civilian noninstitutional population. From Wikipedia
