On August 13, 2019, the D.C. Policy Center’s article, How the D.C. area’s population density has changed since 1970, was cited by Curbed DC:
The population density of the D.C. region has gone up but also spread farther out during the past half-century, according to a recent analysis of U.S. Census Bureau data by a local think tank. The D.C. Policy Center (DCPC) reports that between 1970 and 2010, the last decennial census year, residential areas continued to expand at a remove from the District’s downtown.
“[I]nner suburban densities did increase, though rarely to levels where car-dependence breaks down,” DCPC fellow D.W. Rowlands writes of the changes. “However, the lower-density inner suburbs were replaced by a rapidly growing swath of low-density suburbs further and further outside the Beltway.” Up until 2010, the Mid-City, Capitol Hill, and easternmost parts of the District lost population density, seeing a “hollowing-out effect.”
