Household incomes vary from state to state, but they also vary significantly within a state, from district to district. In the United States, the median household income has risen to $61,372 in 2017, a 1.8% increase from the year before.

About half of all 435 districts represented in the House of Representatives have median household incomes below the national median.

In Texas, which has 36 congressional districts, the difference between the richest and poorest district is more than $57,000 – median income in the richest district is $95,235, 2.5 times the 37,977 income in the poorest district. Such discrepancies are notable in states with few districts as well, even if the gap is smaller. The median household income in Arizona’s nine districts vary by $30,000.

Politics is intertwined with money, but whether a direct correlation between income and political party exists is questionable. Seven of the 10 richest districts are represented by a Democrat, but the ratio is similar with poor districts, too, as six of the 10 poorest districts also are represented by Democrats (two seats are vacant).

To determine the poorest and richest districts, 24/7 Wall St. reviewed the median household income for all 434 districts based on the 2017 Census.
