IN SEPTEMBER I linked to a post at the Political Calculations website showing the 2010 cumulative distribution of income for individuals in America. In that post, I suggested that it might serve as a proxy for household income as well. That suggestion was wrong, and Ironman from Political Calculations kindly provided a link to their 2010 cumulative distribution of household income in America.

Here are the income distributions from those calculators.



I would have been roughly correct if I had also suggested that most American households are dual-income households.

The interactive calculators can be found at the links above.
