D.C. lost at least 17,000 more people during the pandemic than in the prior year, according to USPS data on net moves. At least 9,000 of the loss appears to be permanent.
When the pandemic restrictions were put in place last Spring, there was plenty of anecdotal evidence that people were leaving D.C. as white-collar workers became remote, others were laid off, and schools shut down. Data from the United States Postal Service (USPS), which records changes of address, provides a clue as to how many people left D.C. and where they went.
