Unless stated otherwise, 2014 data are from the one-year ACS file. For information about ACS definitions, methodology, sampling error, and nonsampling error, click here. Estimates from 1990 and 2000 Decennial Census data as well as ACS microdata are from Steven Ruggles, Matthew Sobek, Trent Alexander, Catherine A. Fitch, Ronald Goeken, Patricia Kelly Hall, Miriam King, and Chad Ronnander, "Integrated Public Use Microdata Series: Version 4.0" (Machine-readable database, Minnesota Population Center [producer and distributor], 2011).

Definitions

  • The term "foreign born" refers to people residing in the United States at the time of the population survey who were not U.S. citizens at birth. The foreign-born population includes naturalized U.S. citizens, lawful permanent immigrants (or green-card holders), refugees and asylees, certain legal nonimmigrants (including those on student, work, or some other temporary visas), and persons residing in the country without authorization.
  • The term "U.S. born" refers to people residing in the United States who were U.S. citizens in one of three categories: people born in one of the 50 states or the District of Columbia; people born in U.S. Insular Areas such as Puerto Rico or Guam; or people who were born abroad to at least one U.S. citizen parent.
  • The term limited English proficient (LEP) refers to any person age 5 and older who reported speaking English “not at all,” “not well,” or “well” on their survey questionnaire. Persons who speak only English or who report speaking English “very well” are considered proficient in English.

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 “English proficiency of the foreign born by U.S. citizenship status” and “Educational Attainment by U.S. Citizenship Status”: Data for Alaska, Maine, Montana, North Dakota, South Dakota, Vermont, West Virginia, and Wyoming are from the Census Bureau's pooled 2010-2014 American Community Survey (ACS). Data for the United States overall and for the remaining states are from the 2014 ACS.
