Mean Family Income By Quintiles

See Historical Income Tables: Families from the Census Bureau. They also have a link for Gini coefficients for family income going back to 1947. See also Historical Income Tables: Households.

First I have the mean income, in 2015 dollars, for each quintile and the top 5%, averaged over 5 decades, with the first being 1966-1975. Then a timeline chart. The mean income for the bottom quintile jumped from 16,128 in 2014 to 17,367 in 2015, a gain of about 7.7%. For households it was 6.6%.
