US Mean Income

There is a growing income disparity in the United States, which I find very worrisome. It doesn't seem sustainable and creates a nation of haves and have-nots.

The graph below shows US mean household income, in 2017 CPI adjusted dollars, from 1967 to 2017. It is broken into quintiles and includes the top five percent of earners for comparison. I’ve also added the percentage growth for each line during the 50-year timespan.

I also calculated the ratio of “top five percent”-to-“lowest quintile” for 1967 and 2017.

  • 1967: 17.5/1
  • 2017: 29.0/1
