Note: For 1990, 2000, and current ACS year, the total for the region of birth of the foreign born is different from the total foreign born. This is because the 1990 total excludes those who did not report a country of birth and those born at sea, while the 2000 and the current ACS year totals exclude those born at sea.

Top 3 Countries of Birth

Note: These are the largest countries of birth reported by the Census Bureau. Some countries are only listed as part of a larger geographic region. For example, those born in Somalia are included only among those born in Eastern Africa. Therefore, a few states may have larger populations of foreign-born persons born in countries not listed individually in census data. For each of the three years, countries of birth reflect geographic boundaries as of that year.

Data-related notes

  • The letter N indicates that an estimate could not be provided by the Census Bureau because the number of sample cases was too small for this state.
  • For “Median Age” and “Household Size”: Data for Alaska, Maine, Mississippi, Montana, North Dakota, South Dakota, Vermont, West Virginia, and Wyoming are from the U.S. Census Bureau's pooled 2015-2019 American Community Survey (ACS). Data for the United States overall and for the remaining states are from the 2019 ACS.
  • Region of birth: For 1990, 2000, and current ACS year, the total for the region of birth of the foreign born is different from the total foreign born. This is because the 1990 total excludes those who did not report a country of birth and those born at sea, while the 2000 census and the current ACS year totals exclude those born at sea.
  • Countries of birth: These are the largest countries of birth reported by the Census Bureau. Some countries are only listed as part of a larger geographic region. For example, those born in Somalia are included only among those born in Eastern Africa. Therefore, a few states may have larger populations of foreign-born persons born in countries not listed individually in census data. For each of the three years, countries of birth reflect geographic boundaries as of that year.
  • Beginning with the 2014 ACS, the Census Bureau has excluding children of same-sex married couples from the total number of children. This means that the total number of children may be smaller than in previous years.
  • Children of immigrants: Refers only to children under age 18 who resided with at least one parent. These figures do not include children under age 18 who reside in a home with no parents.
