City residents filed 295,103 change of address requests from March 1 through Oct. 31, according to data The Post obtained from the US Postal Service under a Freedom of Information Act request.

Since the data details only when 11 or more forwarding requests were made to a particular county outside NYC, the number of moves is actually higher. And a single address change could represent an entire household, which means far more than 300,000 New Yorkers fled the five boroughs.

Whatever the exact number, the exodus — which began when COVID-19 hit the city in early spring — is much greater than in prior years. From just March through July, there were 244,895 change of address requests to destinations outside of the city, more than double the 101,342 during the same period in 2019.
