Lists of the wealthiest communities in the United States often feature places with just a few thousand residents. But in looking at a list of the fastest-growing suburbs in the United States, I noticed that some of these fast-growing and large suburbs have high median household incomes. Here are 3 suburbs in the top 5 fastest-growing:

Suburb	Population	Median Household Income
Frisco, TX	210,238	$146,158
McKinney, TX	202,314	$120,273
Santa Clarita, CA	229,021	$119,926

For 2023 (the same year at the end of the data used for this list), the Census Bureau reported that the median household income in the United States was $80,610. The median income means that half of households are above this mark, half are below. These suburbs are way over this mark and they have a lot of residents.

I have wondered about this given my research over the years on Naperville, Illinois. It is a larger suburb – around 150,000 residents – and it is wealthy. In 2023, its median household income is $150,937.

Knowing what I know about Naperville, my guess is that the three communities above are home to thousands of white-collar professional jobs. They have lots of office space. They are home to national and/or regional headquarters for sizable corporations. They have a particular quality of life residents expect.

At the same time, people living in these large and wealthy suburbs might have different experiences from those living in small and wealthy communities in the United States. What does this wealth and access to resources look like on a daily basis? What kind of community engagement and spirit is there? What separates these bigger and smaller wealthy suburbs from the communities around them that are not the same?
