Corrado Gini (23 May 1884 – 13 March 1965) was an Italian statistician, demographer and sociologist who developed the Gini coefficient, a measure of the income inequality in a society. Gini was a proponent of organicism and applied it to nations. Gini was a eugenicist, and prior to and during World War II, he was an advocate of Italian Fascism. Following the war, he founded the Italian Unionist Movement, which advocated for the annexation of Italy by the United States.
