Higher State Taxes = Lower Population Growth
The OLS regression results above further verify that the negative relationship between state population growth and state tax burden is statistically significant at the 1% level (highest level generally reported).
Implication of the OLS Results: Based on the negative regression coefficient of -0.232, we could say that as the state tax burden increases by 1%, population growth decreases by about .23%. Alternatively, we could also say that for every one percent decrease in state tax burden, state population growth would increase by .23%. (For an overview of OLS/linear regression, go here.)
Bottom Line: States with lower tax burdens attract more businesses, workers and people, and states with higher tax burdens lose businesses, workers and people. In other words, these results confirm the theory that if you tax something, you'll get less of it.
