Michigan led the way by establishing a prototype of the women's reformatory in the late 1860s.as a movement to reform the conditions under which women were incarcerated.

The state of Illinois has a flat income tax, which means that everyone, regardless of income, is taxed at the same rate. That makes it relatively easy to predict the income tax you will have to pay. As of the 2015 tax year, the income tax rate in Illinois was reduced from 5% to 3.75%. Illinois also has higher-than-average sales taxes (11th highest in the country when including local rates) and property taxes (2nd highest in the country).
