The typical U.S. household earned $55,322 in 2016, an increase of $1,433 from the year prior. While income in the United States is increasing overall, so is income inequality. The typical household in the wealthiest county earned $2,219 more in 2016 than in 2015, and the typical household in the poorest county earned $356 less.
Incomes vary across counties within a state, and even the wealthier states have relatively poor counties. Factors such as educational attainment, unemployment, and industrial composition affect income differences between counties. Often, the poorest counties tend to have a population with lower educational attainment, higher unemployment, or job opportunities in mostly lower-paying industries.
To determine the poorest county in every state, 24/7 Wall St. reviewed data on median household income for every U.S. county with at least 10,000 residents with data from the U.S. Census Bureau’s American Community Survey
