These surveys, conducted monthly by the U.S. Census Bureau and the U.S. Bureau of Labor Statistics, represent the entire U.S. population, and contain observations for over 130,000 people each month. The survey primarily asks questions focused on the employment status of household members, including whether they are unemployed, out of labor force, wage/salary worker, or a business owner (page 3).
