A Demographic Portrait of Mexican-Origin Hispanics in the United States

A record 33.7 million Hispanics of Mexican origin resided in the United States in 2012, according to an analysis of Census Bureau data by Pew Research Center. This estimate includes 11.4 million immigrants born in Mexico and 22.3 million born in the U.S. who self-identified as Hispanics of Mexican origin.

Mexicans are by far the largest Hispanic-origin population in the U.S., accounting for nearly two-thirds (64%) of the U.S. Hispanic population in 2012. Hispanics of Mexican origin are also a significant portion of the U.S. population, accounting for 11% overall.

The size of the Mexican-origin population in the U.S. has risen dramatically over the past four decades as a result of one of the largest mass migrations in modern history. In 1970, fewer than 1 million Mexican immigrants lived in the U.S. By 2000, that number had grown to 9.8 million, and by 2007 it reached a peak of 12.5 million (Pew Hispanic Center, 2011). Since then, the Mexican-born population has declined as the arrival of new Mexican immigrants has slowed significantly (Passel et al., 2012). Today, 35% of Hispanics of Mexican origin were born in Mexico. And while the remaining two-thirds (65%) were born in the U.S., half (52%) of them have at least one immigrant parent.

Prior to the 1980s, most of the growth in the nation’s Mexican-origin population came from Hispanics of Mexican origin born in the U.S. However, since the 1980s — a decade after the current wave of Mexican migration took off — and up until 2000, more growth in the Mexican-origin population in the U.S. could be attributed to the arrival of Mexican immigrants. In the decade from 2000 to 2010, that pattern reversed — births surpassed immigration as the main driver of the dynamic growth in the U.S. Mexican-origin population (Pew Hispanic Center, 2011).

Mexican immigration has also played a large role in shaping the nation’s immigrant population. Today, 11.4 million Mexican immigrants live in the U.S., making them the single largest country of origin group by far among the nation’s 40 million immigrants. The next largest foreign-born population, from greater China at 2 million, is less than one-fifth the size of the Mexican-born population in the U.S.

In addition, Mexican migration has shaped the nation’s unauthorized immigrant population. More than half (55%) of the 11.1 million immigrants who are in the country illegally are from Mexico.

Among Mexican immigrants, half (51%) are in the U.S. illegally while about a third are legal

permanent residents (32%) and 16% are naturalized U.S. citizens. Overall, naturalization rates among Mexican immigrants who are in the country legally are just half that of legal immigrants from all other countries combined (Gonzalez-Barrera et al., 2013).

Internationally, the U.S. is far and away the top destination for immigrants from Mexico. Fully 96% 0f Mexicans who leave Mexico migrate to the U.S. (Connor et al., 2012) Worldwide, 9% of people born in Mexico live in the U.S. In addition, the U.S. has more immigrants from Mexico alone than any other country has immigrants.

Mexican Immigrants Today and Two Decades Ago

The characteristics of Mexican immigrants have changed over the decades. Compared with 1990, Mexican immigrants in 2011 were less likely to be male (53% vs. 55%), considerably older (median age of 38 vs. 29), better educated (41% with high school or more vs. 25%), and have been in the U.S. for longer (71% had been in the U.S. for more than 10 years, compared with 50%).

On economic measures, Mexican immigrants have mixed results. Although median personal earnings increased by about $2,000 during the last two decades, the median household income of Mexican immigrants suffered a drop of more than $4,500. This reflects the effects of the recent economic recession that drove up unemployment rates in the nation, particularly among Mexican immigrants.

This demographic portrait compares the demographic, income and economic characteristics of the foreign-born and native-born Mexican-origin populations with the characteristics of all Hispanics in the U.S. It is based on tabulations from the 2011 American Community Survey by the Pew Hispanic Center, a project of the Pew Research Center. Key findings include:

• Immigration status. Almost two-thirds of Mexicans in the U.S. are native born (65%). About two-thirds of immigrants from Mexico (65%) arrived in the U.S. in 1990 or later.
• Language. Two-thirds (66%) of Mexican-origin Hispanics ages 5 and older speak English proficiently. The remaining 34% report speaking English less than very well, equal to the share among all Hispanics. About nine-in-ten (89%) native-born Mexicans ages 5 and older speak English proficiently. This compares to about one-in-three (29%) among Mexican immigrants.
• Age. Mexican-origin Hispanics are younger than both the U.S. population and Hispanics overall. The median age of Mexicans is 25; the median ages of the U.S. population and all Hispanics are 37 and 27, respectively. U.S.-born Mexicans are considerably younger than their foreign-born counterparts. The median age of native-born Mexicans is 17, compared with 38 of the foreign born.
• Marital status. Among those ages 15 and older, Mexican immigrants are more likely than native-born Mexicans to be married — 58% vs. 34% respectively. As a group, Mexican-origin Hispanics ages 15 and older are slightly more likely (45%) to be married than Hispanics overall (43%).
• Fertility. Almost one-in-ten (8%) Mexican women ages 15 to 44 gave birth in the 12 months prior to this survey. That was the same as the rate for all Hispanic women — 8% — and slightly higher than the overall rate for U.S. women — 6%. More than four-in-ten (45%) Mexican women ages 15 to 44 who gave birth in the 12 months prior to the survey were unmarried. That was similar to the rate for all Hispanic women — 47% — and greater than the overall rate for U.S. women — 38%.
• Regional dispersion. More than half (52%) of Mexican-origin Hispanics live in the West, mostly in California (36%), and another 35% live in the South, mostly in Texas (26%). There is no significant difference in the regional dispersion of Mexicans by nativity.
• Educational attainment. Mexicans have lower levels of education than the Hispanic population overall. Some 10% of Mexicans ages 25 and older — compared with 13% of all U.S. Hispanics — have obtained at least a bachelor’s degree. Mexicans born in the U.S. are almost three times more likely to have earned a bachelor’s degree than those born in Mexico — 15% vs. 6% respectively. About six-in-ten Mexican immigrants have not earned a high school diploma (59%), compared with 21% of Mexicans born in the U.S.
• Income. The median annual personal earnings for Hispanics of Mexican origin ages 16 and older was $20,000 in the year prior to the survey, the same as for U.S. Hispanics overall. U.S.-born Mexicans had higher earnings than their immigrant counterparts — a median of $22,000 vs. $19,000 respectively.
• Poverty status. The share of Mexicans who live in poverty, 27%, is slightly higher than the rate for Hispanics overall (25%). U.S.-born Mexicans are slightly less likely to live in poverty than their foreign-born counterparts — 26% vs. 29% respectively.
• Health insurance. One-third of Mexicans (33%) do not have health insurance, compared with 30% of all Hispanics. More than half (57%) of Mexican immigrants are uninsured, compared with 20% of those born in the U.S.
• Homeownership. The rate of homeownership (49%) among Mexican-origin Hispanics is higher than the rate for all Hispanics (46%). The rate of homeownership among U.S.-born Mexicans (53%) is higher than that of Mexican immigrants (45%).
