The two reports released by the Center for Immigration Studies provide detailed information on the U.S. labor force. The first, entitled "Jobs Americans Don't Do?," provides a detailed look at the concentration of immigrants across the 465 occupations that comprise the U.S.-labor market. The second report, entitled "Worse Than It Seems," examines the broader measure of unemployment, referred to by the government as U-6, which includes the unemployed and people who would like to work but have not looked for a job recently, as well as those working part-time who want full-time work.
