CITIES WERE A MISTAKE:

In the new Urban Reform Institute report, we identified the fifty high­est‑growth large counties in terms of net domestic migration from 2015 to 2019. These areas grew their population at 7.5 times the rate of the country's other 3,100 counties during this period and gained 1.8 million net domestic migrants. Out of the fifty, all but seven are located in combined statistical areas (CSAs) of more than 500,000 residents. And each of these outer counties are within or close to a two-hour commute time of a central core county. Key areas include Atlanta, Dallas-Fort Worth, and Orlando.

The key demographic headed to these places is young people in prime family formation years. From 2015 to 2019, these counties saw an increase in twenty-five- to thirty-four-year-olds of 12.8 percent, almost four times the 3.4 percent growth rate in the other counties. The high­est‑growth counties also have a far higher rate of school-age children (five- to fourteen-year-olds) per household than the rest of the nation--0.66 compared to 0.43 for the other counties. The highest growth counties have 3.5 times as many school-age children per household as, for example, Manhattan and San Francisco and 75 percent more school-age children per household than other counties in the United States.

This migration is not a repeat of the "white flight" that drove peripheral growth a half century ago. To be sure, during the great mass suburbanization of the mid-twentieth century, many communities--Levittown and Lakewood are well-known examples--excluded ethnic minorities, providing planners and "smart growth" advocates a rationale to claim that single-family neighborhoods are inherently racist ever since. This assertion is seriously out of date, however. Over the past decade, non-Hispanic whites accounted for less than 4 percent of growth in suburbs and exurbs, while Latinos accounted for nearly half, with Asians, African Americans, mixed race, and other groups making up the balance.

These areas tend to be particularly attractive to well-educated immi­grants. The wildly popular Woodlands planned community near Houston is roughly 30 percent Hispanic, African American, and Asian. In Irvine, California, arguably the most successful planned development, a majority of the population is nonwhite and over 40 percent Asian. In the Tres Lagos development in McAllen, Texas, three-quarters of all buyers are middle-class Hispanics, notes developer Nick Rhodes, for houses that average under $200,000. "We have a young population that is looking for larger homes and safety," suggests the twenty-seven-year-old Rhodes. "These are people who cannot afford Irving or even Dallas but want parks and good schools."
