Median household income, explained

What it measures

Median household income is the income that exactly half of all households in a place earn more than, and the other half earn less than. It is the standard summary statistic for "what a typical household here earns", preferred over the mean because the mean is skewed upward by a small number of very high earners. The US Census Bureau publishes median household income for the United States, every state, every county, every incorporated city and town, and most ZIP codes through the American Community Survey (ACS).

A "household" is everyone living together in one housing unit, whether they are related or not. The income figure includes wages and salaries, self-employment income, Social Security and retirement, interest and dividends, public assistance, child support, alimony, and other recurring sources of cash income before taxes. It excludes capital gains, the value of food stamps or housing subsidies, and one-time payments like lottery winnings.

The ACS reports median household income in nominal dollars for the year the data was collected. When you compare two different years, for example 2010 versus 2024, the raw figures will overstate income growth because they have not been adjusted for inflation. CensusEasy stores both nominal and inflation-adjusted (2024 dollars) values, so the time-machine view on each place page shows the real change in purchasing power, not just the change in dollar amounts.

Why it matters

Median household income is the single most-requested number in local-area demographics. Lenders use it to size mortgages and credit lines. Retailers use it for site selection and assortment planning. School districts use it to project Title I eligibility. Cost-of-living calculators use it as the denominator for affordability ratios. Local news outlets use it as the easiest-to-cite measure of economic health. For an individual household, comparing your own income against the local median is the cleanest answer to the question "how am I doing relative to my neighbors?" It is also the foundation for derived statistics like the housing-cost burden rate, the poverty rate, and the income-to-rent ratio that landlords screen against.

How the Census measures it

The figure comes from ACS Table B19013, Median Household Income in the Past 12 Months. The Census Bureau computes it by ranking every responding household's annual income from lowest to highest and picking the middle value (using linear interpolation when the middle falls inside an income bracket). The 5-year ACS pools 60 months of responses, which produces stable estimates even for small places, but it also smooths over sharp year-over-year changes, so a recession or boom shows up in the data two or three years later than it happened in reality. The Census Bureau caps the top reportable median at around $250,000 for places where many households earn above that figure; values at the cap should be read as ">= $250K" rather than as a precise dollar figure.

How to read the numbers

As of the most recent ACS, the US median household income is roughly $80,000. State medians range from about $55,000 in Mississippi to about $105,000 in Maryland; metro medians range wider, from sub-$50,000 in Brownsville, Texas to above $150,000 in the Bay Area. Small wealthy suburbs (Atherton, California; Scarsdale, New York; Highland Park, Texas) routinely report medians above $250,000, the ACS top-code. When comparing two places, focus on the ratio rather than the absolute difference: a $90,000 median in a low-cost city often delivers more living standard than a $130,000 median in a high-cost coastal metro once housing and taxes are accounted for.

Caveats and limitations

Margins of error grow for smaller places. A median reported for a 2,000-household town may carry a ±$10,000 confidence interval, so adjacent ranks in a small-place ranking may not be statistically distinguishable. The figure measures households, not individuals, adding a working-age adult roommate can move a household above the median without anyone earning more. Single-person households drag the median down in cities with lots of young renters; multi-generational households push it up in immigrant-heavy areas. Finally, the income measured is pre-tax cash income, places with high state income taxes deliver less take-home pay than the headline number suggests.
