This week the Pew Hispanic Centre, a research institute, released a report arguing that Mexicans, who once accounted for most of the illegal influx, are now leaving the country in greater numbers than they are entering it
. . .
Hispanics made up 16% of the population in 2010, according to that year’s census. They are a fast-growing group, although a relatively large proportion of them are below voting age and even those eligible to vote are less assiduous about it than Anglos are. But they account for over 20% of the population in several swing states, including Colorado, Florida, Nevada and New Mexico. Democrats hope to make Arizona a swing state this year, thanks both to the 30% Hispanic share of the local population and to the acrimony inspired by the state’s immigration law. A recent poll put Mr Obama within two points of Mr Romney in the state, which has been a Republican stronghold recently—not least because of Mr McCain’s candidacy in 2008.
This is the summary of the report by the Pew Hispanic Center The Economist refers to (source):
The largest wave of immigration in history from a single country to the United States has come to a standstill. After four decades that brought 12 million current immigrants—more than half of whom came illegally—the net migration flow from Mexico to the U.S. has stopped and may have reversed. The standstill appears to result from the weakened U.S. job market, heightened border enforcement, a rise in deportations, the growing dangers associated with illegal border crossings, and changing economic and demographic conditions in Mexico.The report is here with illustrative graphs.
