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.

 

Download Data yearly measures for each state, 1917-2012:

(1)  Top 10% and 1% Income Share Measures

a.    Top 10% and Top 1% - adjusted for compatibility with Piketty and Saez, WTID

                                          i.    Excel File (.xls)

                                         ii.    Stata File (.dta)

b.    Original Data (unadjusted) - includes the threshold values for the Top 10% and Top 1%

                                          i.    Excel File (.xls)

                                         ii.    Stata File (.dta)

(2)  Six Measures of Income Inequality (Atkinson Index, Gini Coefficient, Relative Mean Deviation, Theil Index, Top 10%, and Top 1%)

a.    Excel File (.xls)

b.    Stata File (.dta)

For an explanation of the construction of these measures see the note for WTID: PDF.
