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

 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.

Frank-Sommeiller-Price Series - Annual top income share measures for each state, 1917-2012:

Top 10%, Top 5%, Top 1%, Top 0.5%, Top 0.1% and Top 0.01% income share measures prepared for the World Top Income Database (WTID)

a.    Excel File (.xls)

b.    Stata File (.dta)
