Nationally, the U.S. population only grew by 0.1 percent between July 2020 and July 2021, the lowest rate since the nation’s founding. Pandemic-induced excess deaths, virtually nonexistent international in-migration, and an already-declining birth rate yielded an almost flat population trend nationwide. This, however, belies state-level and regional differences. Whereas the District of Columbia’s population shrunk by 2.8 percent between April 2020 (roughly the start of the pandemic) to July 2021, New York lost 1.8 percent of its population, and Illinois, Hawaii, and California rounded out the top five jurisdictions for population loss, Idaho was gaining 3.4 percent, while Utah, Montana, Arizona, South Carolina, Delaware, Texas, Nevada, Florida, and North Carolina all saw population gains of 1 percent or more.
The picture painted by this population shift is a clear one of people leaving high-tax, high-cost states for lower-tax, lower-cost alternatives. The individual income tax is only one component of overall tax burdens, but it is often highly salient, and is illustrative here. If we include the District of Columbia, then in the top one-third of states for population growth since the start of the pandemic (April 2020 to July 2021 data), the average combined top marginal state and local income tax rate is 3.5 percent, while in the bottom third of states, it is about 7.3 percent.
