U.S. Government Documents 

Current Population Survey
Since the Census is such a vital source of information on many aspects of the national life of the U.S., and it is only taken once each decade, it is important to have good estimations of larger population trends on the "in-between" or non-census years. The Current Population Survey, taken in May and October, with some other data collection points during each year, provides data to make projections of data gathered in the Census. For detailed information and assistance with using the data, please consult the Data and Statistical Services web page to make an appointment with the Data Librarian or a Data Consultant.
