The Mexican American population of the United States has shown two very particular characteristics in its growth during the last decade, according to a new analysis of the U.S. Census Bureau data by the Pew Hispanic Center, a project of the Pew Research Center.
1. For the first time ever the number of babies born in the United States with parents already living in the country has surpassed the number of new immigrants crossing the country from Mexico. From 2000 to 2010 the Mexican American population grew by 7.2 million as a result of births in this county, while the number of those who crossed the border was 4.2 million.
2. Furthermore, the number of Mexicans who crossed the border in the last decade decreased by 500,000 from the 4.7 million who did so between 1990 and 2000.
According to the study, between 2006 and 2010 alone, more than half (53%) of all Mexican-American births were to Mexican immigrant parents. As a group, these immigrants are more likely than U.S.-born Americans to be in their prime child-bearing years. They also have much higher fertility.
At the same time, the study determined from an analysis of Mexican government data that the number of Mexicans leaving for the United States has declined from more than a million a year to 404,000 in 2010 – a 60% reduction. It added that in Mexico recent strong economic growth may have reduced the “push factor.”
The report said that there were 31.8 Mexican-Americans in the United States in 2010, and that this represented 63% of the Hispanic population of the country and 10 % of the whole population of the United States.
