"This report describes the foreign-born population in the United States in 2002. It provides a profile of demographic and socioeconomic characteristics, such as region of birth, geographic distribution in the United States, age, educational attainment, earnings, and poverty status. These characteristics are compared with those of the native population, and because the foreign born are a heterogenous group, variability within the foreign-born population is also discussed. The findings are based on data collected by the Census Bureau in the Current Population Survey (CPS).1 Simply put, the foreign born are those who were not U.S. citizens at birth. Natives are those who were born in the United States or a U.S. Island Area such as Puerto Rico or born abroad of at least one parent who was a U.S. citizen."
