The data for this visualization comes from the American Community Survey which is conducted by the U.S. Census Bureau. I used the Census Bureau API to pull the 2015 5 year estimate for the median household income in each U.S. county. Once I had gathered the data, I used Tableau to create this visualization.
I have included the API code I used to pull the data below. Median household income is represented by DP03_0025E. You will may a free API key to access the data. You can find out more at the Census Bureau’s Developer Page.
