When you begin your search, you will need to determine if you need prepared statistics or raw datasets. The term statistics refers to data that has already been analyzed.
Locating Datasets
If you want to do your own analysis, then you need a dataset. You can find secondary datasets (data that has been collected by someone else) in sources like the ICPSR database (Inter-University Consortium for Political and Social Science Research Datasets) or the U.S. Census.
Data and Statistics in Peer-Reviewed Articles
You can search the Library's research databases for peer-reviewed articles that use statistics to support a position or argument. You may have to try several different searches to find relevant articles. Peer-reviewed articles can be very valuable if you are struggling to locate statistics or data from a government site or database. The Statistics in Articles page includes instructions that show you how to search for articles in the Library's research databases.
