In each state, there was at least one county with a median annual household income more than $7,000 lower than the state’s median income. Virginia and Maryland had counties with median incomes over $35,000 lower than that of the state. 24/7 Wall St. reviewed the poorest county in each state based on data from the Census Bureau’s American Community Survey.
The population of 24 of these poorest counties was predominantly rural. Eight had 100% rural populations. However, in some states, the poorest counties were largely urban. For example, the poorest counties in New York and Pennsylvania had 100% urban populations as of 2010.
