Hispanics of Mexican Origin in the United States, 2011

An estimated 33.5 million Hispanics of Mexican origin resided in the United States in 2011, according to the Census Bureau’s American Community Survey. Mexicans in this statistical profile are people who self-identified as Hispanics of Mexican origin; this means either they themselves are Mexican immigrants or they trace their family ancestry to Mexico. Mexicans are the largest population of Hispanic origin living in the United States, accounting for nearly two-thirds (64.6%) of the U.S. Hispanic population in 2011.1

This statistical profile compares the demographic, income and economic characteristics of the Mexican population with the characteristics of all Hispanics and the U.S. population overall. It is based on tabulations from the 2011 American Community Survey by the Pew Hispanic Center, a project of the Pew Research Center. Key facts include:

About the Data

This statistical profile of Hispanics of Mexican origin is based on the Census Bureau’s 2011 American Community Survey (ACS). The ACS is the largest household survey in the United States, with a sample of about 3 million addresses. The data used for this statistical profile come from 2011 ACS Integrated Public Use Microdata Series (IPUMS), representing a 1% sample of the U.S. population.

Like any survey, estimates from the ACS are subject to sampling error and (potentially) measurement error. Information on the ACS sampling strategy and associated error is available at http://www.census.gov/acs/www/methodology/methodology_main/. An example of measurement error is that citizenship rates for the foreign born are estimated to be overstated in the Decennial Census and other official surveys, such as the ACS (see Jeffrey Passel. “Growing Share of Immigrants Choosing Naturalization,” Pew Hispanic Center, Washington, D.C. (March 28, 2007)). Finally, estimates from the ACS may differ from the Decennial Census or other Census Bureau surveys due to differences in methodology and data collection procedures (see, for example, http://www.census.gov/acs/www/Downloads/methodology/ASA_nelson.pdf, http://www.census.gov/hhes/www/laborfor/laborfactsheet092209.html and http://www.census.gov/hhes/www/poverty/about/datasources/factsheet.html).
