WASHINGTON, April 15 (UPI) -- A U.S. think tank said Wednesday the latest figures conclude there are nearly 13 million Mexican immigrants living in the United States.
The Pew Hispanic Center said 55 percent of those 12.7 million immigrants were "unauthorized" and Mexicans now account for 32 percent of all immigrants in the United States.
The report, which was issued in the eve of President Obama's trip to Mexico, was based on a March 2008 Current Population Survey.
Pew said in a written statement that the number of Mexicans living in the United States increased 17 fold over 1970, and it is estimated one of every 10 living persons born in Mexico now lives in the United States.
The number of Mexican immigrants in the United States, in fact, outnumbers the total immigrant population of every other nation.
The average Mexican immigrant is described in the report as a married male living in a large household with lower incomes and less education than U.S.-born populations.
