"Unauthorized Migrants: Numbers and Characteristics" was prepared by Jeffrey S. Passel, a veteran demographer and senior research associate at the Center, using a well-established methodology to analyze data from the March 2004 Current Population Survey, which was conducted by the Census Bureau and the Bureau of Labor Statistics.
