How to Read a Median Household Income Figure

Median household income is the most quoted demographic statistic in America, and one of the most misread. It shows up in city-council debates, real-estate listings, “best places to live” rankings, and just about every profile on this site. Across the country the figure sits at $78,538. That single number carries a lot of freight, and most of the ways people use it are slightly wrong.

Here is what the figure is actually measuring, and how to read one without drawing the wrong conclusion.

A median is a middle, not an average

Line up every household in a place from lowest income to highest and walk to the exact center of the line. The income of the household standing there is the median. Half of all households earn less; half earn more.

That is different from an average (the mean), which adds up all the income and divides by the number of households. The distinction matters more than it sounds. Averages are dragged upward by a handful of very high earners. If a small town of a thousand modest households happens to include one hedge-fund founder, the average income lurches upward while the median barely moves. The median is the town most residents would recognize; the average is a number no one actually earns.

This is exactly why the Census Bureau leads with the median. It answers the question people really mean when they ask what a place earns: what does a typical household here bring in?

Household, family, or per person — three different numbers

“Income” is not one measurement. The Census publishes several, and they are not interchangeable:

• Median household income counts everyone living together in a housing unit, related or not — a married couple, a group of roommates, a single retiree living alone. It’s the broadest and most commonly cited figure, and the one we use throughout this site.
• Median family income counts only households of two or more related people. It runs higher than household income, because it excludes people living alone (who tend to be younger or older, and earn less).
• Per capita income divides all income by every person, including children and non-earners. It’s always the lowest of the three and can’t be compared to the household figure at all.

A place can look richer or poorer depending on which one gets quoted. When you see an income figure with no label, it is usually household income — but it’s worth confirming before you compare two sources, because mixing family income from one and household income from another produces a gap that’s pure artifact.

The dollars are inflation-adjusted, but only to one year

The estimates here come from the Census Bureau’s American Community Survey, pooled over five years of responses. To keep a 2019 paycheck comparable to a 2023 one, the Bureau adjusts every dollar to the final year of the period using the national price index. So the figures are inflation-adjusted, which is good.

What that adjustment does not do is account for where you live. A dollar of income is counted the same in rural Mississippi and in San Jose, even though it buys very different amounts of housing, childcare, and groceries. Income data alone will tell you a coastal metro earns far more than a Plains town; it won’t tell you which household has more left over at the end of the month. For that you have to set income next to the local cost of living — which is the whole point of pairing an income figure with a home-affordability estimate.

One number hides the whole spread

Two places can share an identical median and be built completely differently underneath. Median income tells you where the middle sits, not how far apart the top and bottom are.

Picture a college town where nearly everyone clusters near the middle, and a coastal city split between a large low-wage service class and a thick band of six-figure professionals. Both can land on the same median while feeling like different economies — one flat, one stretched. The middle household is the same; almost nothing else is. Every city profile on this site pairs the median with an income-bracket breakdown precisely because the shape of the distribution is where the real story usually hides.

If you want to see where your own household lands in that spread, the income percentile calculator puts any figure in national and state context.

When a place has no income figure at all

Look up a very small town and you may find the income field blank. That is not an error, and it is not the Bureau hiding something. The American Community Survey is a sample, not a full count. In a place of a few hundred people, too few households land in the sample to produce a reliable estimate, so the Bureau declines to publish one rather than print a number it can’t stand behind.

The same logic explains the ceiling at the top. The survey stops recording household income above $250,001 — a practice called top-coding, meant to protect the privacy of the highest earners. A wealthy enclave shown at exactly that figure isn’t earning precisely a quarter-million dollars; it means the true median is at least that high and the survey stops counting there. You’ll see this most in the very richest cities and suburbs.

Reading one in practice

When you come across a median household income, a few quick questions keep you honest. Is it household, family, or per capita income? What year’s dollars is it in, and does the comparison you’re making hold the cost of living constant? And is the middle really the story here, or is the spread around it doing the work?

Ask those, and a number that looked like a verdict turns back into what it actually is: one useful landmark in a much larger picture. The rest of that picture — housing, education, age, poverty, and the distribution behind the median — is what the full profile for any place is there to fill in.
