This shows county median home values divided by county median household income, both for 2023.
For example a score of “5” means the median home price in that county is 5 times the median household income in that county.
Generally, a score under 4 is considered affordable, 4-6 is pushing it, and over 6 is unaffordable for the median income.
There are of course other factors to consider such as property tax, down payment amount, assistance programs, etc. Property tax often varies at the city/township level so is impossible to accurately show.
Median Household Income Data is from US Census Bureau.
Median Home Value from National Association of Realtors, and Zillow/Redfin .

Important to note this is based on “median home values,” not “housing affordability.”
This map does not take into consideration many directly-related-to-housing costs such as: utilities cost, natural disaster-related costs, insurance rates, property tax rates, etc. It also does not take into consideration other cost-of-living factors such as: transportation costs (how much are you spending on gas every month if you live 50 miles from anything?), necessities costs (e.g. food and other essentials), and opportunity costs (for everything else).
