As expected, the July 1, 2020 county population estimates came out yesterday. Here's a map of the 7/1/19-7/1/20 county percentage population change:
As expected, the estimates used 2010 Census as base, not 2020, meaning NY's count is "only" off by 800K+. Every NYC borough supposedly lost population year-over-year. Take that with a huge grain of salt.
The Vintage mid-2021 estimates are scheduled for release on a flow basis beginning in December 2021. This series will incorporate the results of the 2020 Census.
