New Geography reports:
The youth population expanded in 31 of the 51 metro areas from 2000 to 2010. The 10 regions that posted the strongest growth were in Texas, the Southeast and the Intermountain West. Leading the nation is Raleigh, N.C., where the number of children under 15 rose a whopping 45%, or 77,421. Texas is experiencing something of a baby boom, paced by Austin, second among America’s largest metro areas with a youth population expansion of 38%; Dallas-Ft. Worth (sixth); Houston (eighth); and San Antonio (11th).
Where's the non-growth?
Take New York, our greatest city and one that has experienced considerable improvement in quality of life over the last two decades. Yet despite this, the under 15 population of New York County (Manhattan) dropped nearly 10% over the past decade, a net loss of 21,000. Barely 12% of Manhattanites are under 15, far below the national rate of 19.8%. Similar declines have occurred as well in Brooklyn, a borough that many priced-out Manhattan couples have seen as a refuge for young families.
