More Evidence That State Income Taxes Have Little Impact on Interstate Migration: The New York Times’ Upshot blog has published a fascinating set of graphs of Census Bureau data on interstate migration patterns since 1900, bolstering our argument that state income taxes don’t have a significant impact on people’s decisions about where to live.
We plotted the same Census data, which shows which states do the best job of retaining their native-born populations, on the chart below, also noting which states have (or don’t have) a state income tax. Our chart shows that taxes have little to do with the extent to which native-born people leave their states of origin.
If Heritage Foundation economist Stephen Moore’s claim (which other tax-cut advocates often repeat) that “taxes are indisputably a major factor in determining where . . . families locate” were true, states without income taxes would see below-average shares of their native-born populations leaving at some point in their lifetime, while states with relatively high income taxes would see the opposite. But the graph shows no such pattern...
