Mexican Demographics & Immigration
Thanks to a decades-long family-planning campaign, most Mexicans are having far fewer children than was typical a generation ago... [I]n 1968, the average Mexican woman had nearly seven children. Today, the figure is just above two, comparable to the U.S.
This sweeping demographic shift has fostered hope that someday Mexico will produce a healthy middle class... Most Mexicans today are far too poor for luxuries... But the new, smaller Mexican family may help change that by allowing parents to invest more in their children's education, finally producing the generation that lifts Mexico into the developed world.
Mexico's new demographics could have a big impact on the U.S. Although the flood of Mexicans heading north is whipping up debate in Washington, the crossings may slow in future decades. That could happen simply because smaller families limit the pool of potential migrants. A slowdown would be especially likely if a growing middle class makes more Mexicans comfortable at home and averse to risking a dash across the border.
