" The foreign born are persons residing in the United States who were not U.S. citizens at birth. That is, they were born outside the United States or one of its outlying areas such as Puerto Rico or Guam, to parents neither of whom was a U.S. citizen. The foreign-born population includes legally-admitted immigrants, refugees, temporary residents such as students and temporary workers, and undocumented immigrants.
The native born are persons born in the United States or one of its outlying areas such as Puerto Rico or Guam or who were born abroad of at least one parent who was a U.S. citizen.
The data on nativity are collected as part of the Current Population Survey (CPS). The CPS is a monthly survey of about 60,000 households that obtains information on employment and unemployment among the Nation's civilian noninstitutional population ages 16 and older.
