Data item: Resident population: Hispanic or Latino Origin, percent, 2010

Source: U.S. Bureau of the Census, County Population Estimates by Demographic Characteristics - Age, Sex, Race, and Hispanic Origin; updated annually for states and counties. 2010 Census of Population and Housing for places; updated every 10 years.


Hispanics or Latinos are those people who classified themselves in one of the specific Spanish, Hispanic, or Latino categories listed on the Census 2010 questionnaire -"Mexican," "Puerto Rican", or "Cuban"-as well as those who indicate that they are "another Hispanic, Latino, or Spanish origin." People who do not identify with one of the specific origins listed on the questionnaire but indicate that they are "another Hispanic, Latino, or Spanish origin" are those whose origins are from Spain, the Spanish-speaking countries of Central or South America, or the Dominican Republic. The terms "Hispanic," "Latino," and "Spanish" are used interchangeably.

Origin can be viewed as the heritage, nationality group, lineage, or country of birth of the person or the person's parents or ancestors before their arrival in the United States.

People who identify their origin as Spanish, Hispanic, or Latino may be of any race. Thus, the percent Hispanic should not be added to percentages for racial categories.

NonHispanic White persons are those who responded "No, not Spanish/Hispanic/Latino" and who reported "White" as their only entry in the race question. More complete tallies that show race categories for Hispanics and nonHispanics separately are also available.

Scope and Methodology:

The 2010 data on the Hispanic or Latino population were derived from answers to a question that was asked of all people in Census 2010.

Estimates for states and counties for years after 2010 are developed using a cohort-component method whereby each component of population change - births, deaths, domestic migration, and international migration - is estimated separately for each birth cohort by sex, race, and Hispanic origin.
