Mexican Immigrants in the United States, 2008
A record 12.7 million Mexican immigrants lived in the United States in 2008, a 17-fold increase since 1970. Mexicans now account for 32% of all immigrants living in this country. The second-largest nationality group of immigrants, Filipinos, accounts for just 5% of all immigrants in the U.S.
More than half (55%) of the Mexican immigrants in this country are unauthorized. Overall, Mexicans comprise about six-in-ten (59%) of the estimated 11.9 million unauthorized immigrants in the U.S.
No other country in the world has as many total immigrants from all countries as the United States has immigrants from Mexico alone. Other than the U.S., the country that hosts the largest number of immigrants is Russia, with 12 million foreign born, many of whom are natives of countries that were part of the former Soviet Union.
