The U.S. Bureau of Labor Statistics (BLS) collects unemployment and labor force participation data for a variety of groups of Americans (by age, gender, race, level of education, location, etc.). This data is available http://www.bls.gov. (You can find lots of specific data by looking at the bottom right side of the BLS homepage under the heading Latest Numbers, then clicking on the table icon to the right of the Unemployment Rate. This link will take you to a page with lots of links to detailed information. For example, the link to Table A-2 send you to unemployment data sorted by age, sex, and race.)
