Fortunes can vary widely from one neighborhood to the next and also from one state to the next. The map above, which looks at U.S. states, shows median household income. This measure of income is basically a line through the middle: Half the households within that state receive more income and half receive less income. The map shows some regional correlations, but it is quite interesting to see how median income in one state can be almost twice as high (or low) as it is in a neighboring state. Use the “View on GeoFRED” link above to visit the site. There you can interact with each state on the map and gather more details about it. You can also change the applicable date to see how the distribution of the median income has changed over the years.
How this map was created: Go to GeoFRED and click on “Build New Map.” Open the tool bar in the top left corner: Under “Region Type,” select “State.” Under “Data,” search for and select “Estimate of Median Household Income.”
