Current information on employment, unemployment, and related data are compiled each month from the Current Population Survey of the Bureau of the Census. This survey is conducted each month with a scientifically selected sample representing the noninstitutional civilian population. The results are announced in the Combined Employment and Unemployment Release issued jointly by the Departments of Commerce and Labor; the joint release, issued as a press statement, presents the information from the survey together with related data from the Department of Labor. Fuller details from the Current Population Survey are issued in the Bureau of the Census "The Monthly Report on the Labor Force," Current Population Reports, Series P-57. A discussion of the underlying concepts and a description of the methods used in the preparation of these statistics follow.
