I recently found a list of wealthy American with the most population growth. But I noticed that the list ends with two suburbs that lost population during the time period of interest (2018-2023). I suspect this might be because how they selected the communities on the list.

Methodology: For this study, GOBankingRates analyzed suburbs to find the fastest-growing wealthy suburbs in America. First GOBankingRates found the places with a population between 25,000 and 100,000 according to the U.S. Census American Community Survey. The metro area for each location was found and only the metro areas with a population of 1 million or more were kept. With these suburbs isolated, the numerical and percentage change in population from 2018 to 2023 were found for each city using data from the American Community Survey Census from 2018 and 2023. For each location, GOBankingRates found total population, population ages 65 and over, total households, and household median income all sourced from the American Community Survey. Only places with a median household income of $150,000 or more were kept for this study. Using this data the percentage of the population ages 65 and over were calculated. The cost-of-living indexes were sourced from Sperling’s BestPlaces and include the grocery, healthcare, housing, utilities, transportation, and miscellaneous cost of living indexes. Using the cost-of-living indexes and the national average expenditure costs, as sourced from the Bureau of Labor Statistics Consumer Expenditure Survey, the average expenditure cost for each location were calculated. The livability index was sourced from AreaVibes for each location and included as supplemental information. The average single-family home value was sourced from Zillow Home Value Index for November 2024. Using the average single-family home value, assuming a 10% down payment, and using the most recent national average 30-year fixed mortgage rate, as sourced from the Federal Reserve Economic Data, the average mortgage can be calculated. Using the average mortgage and average expenditure costs, the average total monthly and annual cost of living were calculated. The cities were sorted to show the highest percentage population increase first to show the places with the fastest-growing wealthy suburbs in America. All data was collected on and is up to date as of Jan. 6, 2025.
The bigger question is this: how many suburbs in the United States of population 25,000 to 100,000 have median household incomes over $150,000? I suspect this is not a huge list. Hence, there are only 28 suburbs who meet this criteria and grew between 2018 and 2023.
But it may not take much to change the parameters to include more suburban communities on the list. For example:
- What if the median household income was $140,000? Is there a strong reason for leaving the cutoff at $150,000?
- Why limit the population to communities between 25,000 and 100,000? If the list could includ communities between 10,000 and 100,000, are there now more growing wealthy suburbs?
- Limiting the analysis to metropolitan areas with 1 million people reduces the number of possible regions and suburbs. If the cutoff is 1 million people in an MSA, this means a little over 50 regions are included. Lower the region’s population and you would have more suburbs that might meet the criteria.
- Change the list from 30 suburbs to 20 and then the last one on the list would have 5% population growth.
