March of the Non-White Babies - CityLab

From Tanvi Misra at CityLab we have this article, click title for link, that has particular relevance to south Florida and Lake Worth particularly. Demographer William Frey is the expert cited in the piece called, "March of the Non-White Babies": Here is a short excerpt:

The share of so-called "new minorities"—Hispanics, Asians and multi-racial groups in America—is going to double. If your first guess is that this is all due to immigration, you're not entirely wrong—it's because of past immigration. What's really driving the growth now (and will continue to do so in the future) is that majority of the immigrants who are already here are at the baby-making age.
"Back in the 1950s, we had a lot of Americans across the board in their childbearing years—we had all these babies," Frey explains. "Now, that's really only the case for some of the newer minorities."
This is good news, demographically speaking, because as it turns out, the white population in the U.S. is aging pretty rapidly. This surge in minority births will arrive just in time to pick up the slack, Frey says. Absent any major change in immigration policy, the future of the American labor market will depend on the next generation of U.S.-born minorities.
