U.S. Household Incomes

Visualizing the median household income in all 3,000 + U.S. Counties

The 2012 - 2016 American Community Survey is a massive 5-year study conducted by the U.S. Census Bureau that provides estimates on different demographic and economic numbers across the U.S.

I'm always intrigued by the income data that comes from this survey because it's so granular. In particular, the survey shares income statistics for every single county in the U.S.
