What Qualifies as Middle-Income in Each State

By Nathan Yau

What qualifies as lower, middle, and upper income? There are various definitions, but the Pew Research Center defined middle-income as two-thirds to double the median. Upper is then everything that is greater than double the median, and lower is everything that is less than two-thirds the median.

Here’s what you get when you apply this definition to each state and adjust for household size.

Household Middle-Income

Bars represent a range for each state, sorted by median and adjusted for household size.

 

This is based on data from the 2017 five-year American Community Survey. I was surprised to see so much variation in rankings when you move between household sizes.

For example, California is towards the top for smaller households, but then shifts towards the middle once you get to five-person households. Montana, on the other hand, shifts in the opposite direction. Makes me wonder how these differences relate to family types.

Percentage of Households in Each Income Level

With the thresholds, we can estimate the overall breakdowns.

Notes

  • The data comes from the 2017 5-year American Community Survey. I downloaded the data via IPUMS.
  • I used R to analyze and process the data. I used D3.js to make the chart.
