Connecticut’s problem of income inequality is especially acute. In 1970, Connecticut was the 36th most unequal state, today it is second. The Gini coefficient is the most commonly used measure of income inequality. It ranges from 0, a condition of perfect equality where all members of a population receive identical amounts, to 1, a condition of perfect inequality, where one member of a population receives everything. Between 1970 and 2015, the Gini coefficient for Connecticut increased from .337 to .492. Income inequality increased in every state over this time, but Connecticut, by far, had the largest increase. The increase was more than 50% greater than the average for the other states.
