U.S. State-Level Income Inequality Data - Mark W. Frank

 

Videos - Evolution of the Top Income Shares by State: 1916-2011

The above are short videos I put together showing the state-level evolution in the top income shares over the past century. They play via YouTube.

 

 

 

My current research offers a comprehensive panel of annual state-level income inequality measures that I have constructed from individual tax filing data available from the Internal Revenue Service.

* See my working paper (listed below) for important caveats and limitations of IRS-based measures of income inequality. This update also fixes several data errors in prior versions. The “raw” version omits the small-sample adjustment for relevant years (1974, 1982-88, 2002-09).

Next update expected (2012 data): May/June 2014.
