Will data analysis be part of your project? Using SPSS, R or another statistical software package? Great! But where will you find your data? Try the sources below, or contact your librarian!
Depending on your project you may need to create your own data, or request it from a local government agency. However, there's a lot of data on the web for free. Much of it is created and provided by government entities, some is provided by Universities or data clearinghouses that gather many sources of data in one place.
For information on Census data, see the U.S. Census Information Guide.

Every country collects data a little differently, and may have slightly different definitions for terms. IGOs take information reported by various countries and normalize them so comparisons can be made across countries and across time. If you ever want to compare two countries, IGO data should be your first choice if avaialble. (But it is still important to read about the methodology behind the data!)
If you are studying only one country, or need more detailed data or statistics than is provided by an IGO, the statistical department of a country's government may be your best source. See Northwestern University's list of foreign government websites, including statistical divisions for more.
