U.S. Neighborhood Income and Inequality in the 2005-2009 Period

What is the income inequality index for your state? See the Tableau chart below.
The following data announcement was released 10/26 by the U.S. Census Bureau.
"WASHINGTON, Oct. 26, 2011 /PRNewswire-USNewswire/ -- Presents analysis of household income inequality using statistics from the 2005-2009 American Community Survey for the nation, states, metropolitan areas, places and census tracts. The Gini index is used for analysis of all these areas. Included is an analysis of the characteristics of census tracts associated with higher or lower inequality. (Census tracts and places with fewer than 50 interviews in the five-year period under study are excluded from the analysis.) Internet address: http://www.census.gov/prod/2011pubs/acs-16.pdf."
I have converted the state-level data. Three measures are used: the Gini index, P90/10, and P95/20. Google "Gini index" here. I have noted the P9*/* index definition in the chart.
