Per capita personal income and Median household income (model-based)
Across 3,069 counties, Per capita personal income and Median household income (model-based) have a link of +0.63, on a scale from −1 (opposite) to +1 (in step). But compare places with the same population density, income and education, and a weak link of +0.22 remains. Most of the first figure came from both measures following how urban, rich and educated a place is, not from a link with each other.

Every place, plotted
One dot for each place reporting both measures. Hover over or tap a dot to see its name and values. The thin line is the straight line that best fits the dots. The bold line, shown for counties, is the link after adjusting for density, income and education. A dot far from the lines is a place that does not follow the pattern.

Per capita personal income
Personal income divided by the number of residents, children included.

Median household income (model-based)
The income of the middle household. It is an estimate from a statistical model that combines survey answers with tax and government-program records.

Highest and lowest
Where each measure is highest and lowest among the places reporting both (2023), with the other measure beside it. This is shown for every size of place where both are published. Metro-area values are added up from their counties. A measure that cannot be added up across counties, such as a middle value (median), has no metro figure. Counts are shown per 1,000 residents, since raw totals would only list the largest places. Cities and towns and ZIP codes are shown where the Census survey or the CDC publishes them; most other sources stop at the county. They are shown for places of 5,000 residents or more, and only where the survey’s margin of error is small enough for the figure to be usable. The CDC publishes its health estimates for cities in a version adjusted for age, so places with older or younger people can be compared fairly, but not for ZIP codes.

Counties furthest from the pattern
Compared with the straight line that best fits all 3,091 counties: the five with far more median household income (model-based) than their per capita personal income would suggest, and the five with far less.

Two series, one county
Both measures over time for a county you pick. The two charts are stacked, so they share only the years along the bottom. You can pick from the thirty largest counties reporting both. This panel covers 2010–2024, and a measure published only once shows as a single dot.

Every version of the link
Each row measures the same link, from −1 to +1, in a different way. If the rows mostly agree, the link does not depend on one choice of method.
| Before adjusting for anything | +0.629 | 3,069 counties reporting both |
| After adjusting for density, income and education | +0.218 | the part of the link that is not just how urban, rich and educated a place is |
| Also adjusting for population size | +0.225 | size taken out as well as density |
| Also comparing only within each state | +0.239 | each county is compared only with others in its own state, so this is no longer a comparison between states |
| Giving bigger counties more weight | +0.041 | the adjusted link for the average resident rather than the average county. With this weighting, the data counts for about 282 equally weighted counties |
| Middle value inside single states | +0.689 | the link worked out inside each of 40 states with at least 20 counties reporting |
| Using ranks, after adjusting | +0.221 | uses each county’s rank, not its value, so a few extreme counties cannot create the link |
How much to believe it
Could it be chance?
The p-value is the chance of seeing a link this strong if there were really none. A value of 0.05 or less means the link is unlikely to be chance. Very small values are written in short form: 3.1e-16 means 0.00000000000000031, and the bigger the number after “e-”, the smaller the value. Treating every county as a separate case gives p = 1.9e-34. But counties in the same state tend to resemble each other, so the better figure allows for that: p = 1.5e-10. The site tested 20,910 pairs, and testing so many turns up some flukes. The q-value allows for that too. For this pair it is 8.2e-34.
Do nearby places look alike?
Moran’s I measures how much nearby places look alike: 0 means no map pattern, and higher means neighbours are more similar. For the part of each county that the adjustment leaves unexplained, it is +0.09 (p = 0.001). Once the adjustment is made, little map pattern is left.
Did they change together?
The figures above compare counties at one moment. This asks a different question: where per capita personal income rose most, did median household income (model-based)move too? Each county’s change is compared with the average change in its own state. That takes out ups and downs that hit a whole region at once. Each change is the gap between two estimates that both contain some error. That error pulls these links towards zero, so a weak one is weak partly for that reason. The q column shows whether a link could be a fluke, allowing for the many pairs tested: 0.05 or less means it is unlikely to be chance.
| Period | Counties | Change together | Within states | q |
|---|---|---|---|---|
| 2014–2019 the main test: each Census survey figure averages five years, and these two do not overlap; before the pandemic | 3,080 | +0.38 | +0.27 | 2.3e-12 |
| 2019–2023 a repeat check: its two five-year survey figures both include 2019, and it covers the COVID years | 3,080 | +0.12 | +0.11 | 0.000 |
In counties where one changed more, the other tended to move the same way, compared with other counties in the same state (r = +0.27). The same holds in the second period. How change is measured.
