Common questions
What is the richest state in the U.S.?
By median household income, Massachusetts, at $104,828 in 2024. Its lead over the next states may not be statistically significant; the findings below list any state tied with it at 90% confidence.
What is the poorest state in the U.S.?
By median household income, the poorest state is Mississippi, at $59,127 in 2024.
Are these incomes adjusted for the cost of living?
No. These are dollar incomes. The price-adjusted household income ranking divides each median by the state’s price level, and the cost of living ranking shows the price levels themselves.
What this ranking measures
The midpoint of household income over the past 12 months, expressed in 2024 dollars. Half of households have more income and half have less.
Household income is not individual pay or wealth. It is not adjusted for differences in prices between states.
The size of the gap
The difference between the highest and lowest state estimates is $45,701. The U.S. benchmark is $81,604. It is not a simple average of the states.
19 states have point estimates above the U.S. benchmark and 31 below it. These counts do not establish statistical significance.
How much should you read into a rank?
Each estimate has a 90% margin of error published by the Census Bureau. For two different states, we flag a difference only when its absolute size exceeds the square root of the sum of their squared margins of error. The comparison tool applies this check to every selected pair.
Non-significance is not proof of equality. These pairwise tests are not adjusted for multiple comparisons and do not form ranking confidence intervals. Statistical method and limitations.
Ranks use the full precision of the source file, so only truly equal values share a rank (1, 2, 2, 4).
