Remember all the talks about how an exploding Mexican population will reclaim the territories lost to the USA in 1848? It turns out very soon they will have the same sub-replacement birthrate south of the border. Humans will act the same everywhere when their conditions converge.
From the USA Today: "What Mexican immigration problem?"
"President Obama's executive action on immigration enraged Republicans, but has also widened the split between two camps within the GOP.
Underlying this debate is at least one shared assumption: There are — and always will be — millions of Mexicans ready to move permanently to the United States. What if that assumption is now completely wrong?
But in 2001, the number of new residents (based on U.S. Census Bureau data) started to drop. In 2005, it began to plunge, bottoming out at 140,000 in 2010 and has flat lined since then. Most analysts attribute the steep drop of the last decade to the collapse of the U.S. housing market in 2006 and the lingering recession following the financial crisis in 2008.
But a bigger factor has been at work in Mexico that will drive net migration numbers to very low levels — close to zero — for at least the next one or two generations and probably much longer. Mexico, known for massive and rapid population growth for most of the 20th century, is now on the same downward demographic spiral as the rest of the developed world, including most of Latin America.
In the early 1960's, the total fertility rate for Mexican women was around seven children. By 2013, the rate was down to 2.2, just above the replacement rate of 2.1. The absolute number of live births in Mexico has fallen every year since 1994, and a UN population analysis projects that Mexico will sink below the replacement rate around 2025. Once countries go below the magic fertility number of 2.1 it isn't long — about 30 years — before their population growth completely halts and then starts to shrink.
In the meantime, those steep fertility declines already have shown up in the falling immigration numbers, as the pool of Mexican 15-39 year olds — the prime age to migrate — grows smaller and smaller year after year.
