Dmitriy T.M. and Jeff H. sent in a link to Mapping the Measure of America, a website by the Social Science Research Council that provides an amazing amount of information about various measures of economic/human development in the U.S. Here’s a map showing median personal (not household) earnings in 2009:
The District of Columbia has the highest, at $40,342; the lowest is Arkansas, at $23,470 (if you go to their website, you can scroll over the bars on the left and it will list each state and its median income, or you can hover over a state).
You can break the data down by race and sex as well. Here’s median personal income for Native American women, specifically (apparently there is only sufficient data to report for a few states):
Native American women’s highest median income, in Washington ($22,181), is lower than the overall median income in Arkansas, which is the lowest in the U.S. as we saw above.
Here is the percent of children under age 6 who live below the poverty line (for all races):
Life expectancy at birth differs by nearly 7 years between the lowest — 74.81 years in Mississippi — to the highest — 81.48 years in Hawaii:
It’s significantly lower for African American men, however, with a life expectancy of only 66.22 years in D.C. (again, several states had insufficient data):
The site has more information than I could ever fully discuss here (including crime rates, various health indicators, all types of educational attainment measures, commuting time, political participation, sex of elected officials, environmental pollutants, and on and on), and it’s fairly addictive searching different topics, looking data up by zip code to get an overview of a particular area, and so on. Have fun!
