The results show that on average the population of each state is increasing by 7.127% when the state legislature is controlled by all Republicans. If the state legislature turns from entirely Republican to entirely Democrat, the state's population increase will fall by 10.04 percentage points so that the state will over the decade be losing population at a rate of -2.913. The result is statistically significant with a two sided T-Test with a P-Value of .0129. The R-Squared is low at .068 which suggests that there are many other reasons for leaving a state besides the ruling political party. The low R-Squared is a weakness in this regression.
