The rate of Mexican immigration to the US has stalled or maybe even gone into reverse, an analysis shows, ending a four-decade-long trend.
Economic factors, increased border control, and lower Mexican birth rates were all cited as factors.
More than 12 million migrants entered the US from Mexico since 1970, more than half legally, the report says.
"Looking back over the entire span of US history, no country has ever seen as many of its people immigrate to this country as Mexico has in the past four decades," the report's authors note.
However, figures clearly show major changes to the long-term trend over the years 2005-2010.
A decade earlier, from 1995-2000, some 2.9 million Mexicans arrived in the US, with just 670,000 people leaving the country for Mexico - a net influx to the US of more than 2.2 million people.
Between 2005-2010, though, just 1.37 million arrived from Mexico - and 1.39 million left to cross the southern border.
Well, this certainly is a surprising tread. If it continues it could be a big factor in future immigration debates. But I don't think that we'll see that any time soon. But immigration is still a big issue among Hispanic voters and there's no doubt they're a big block in the next election. What amuses me is that Hispanics are pretty firmly behind Obama even though he's taken a fairly firm stance on immigration then again, Romney's "self-deportation" line would be laughable if it wasn't so eyeroll inducing.
Whatever the case, this is clearly a trend to watch.
