The Boomer Belt: Which US Metro Areas Have the Oldest Adult Populations in 2024?

The Boomer Belt: Where Older Adults Are Concentrating

By 2024, the US median age surpassed 39, and the 65+ population grew to nearly 59.2 million—a 9.4% increase since 2020. But where are older adults clustering? Let’s talk about the Boomer Belt, a swath of Southern metro areas that are rapidly aging due to baby boomer retirements and migration patterns. I’ve dug into the Census Bureau data, and the trends are clear: places like Myrtle Beach, SC, and Lakeland-Winter Haven, FL, are becoming hubs for retirees.

First, let’s quantify the stakes. Take Myrtle Beach-Conway-North Myrtle Beach, SC, which saw a staggering 23.1% increase in its 65+ population from 2020 to 2023. Wilmington, NC, and Raleigh-Cary, NC, aren’t far behind, with 18.4% and 18.3% growth, respectively. Even Florida’s Orlando metro area, known for its tourism, is attracting older adults at an unprecedented rate. This isn’t just anecdotal; it’s a structural shift driven by demographics and migration. Census data confirms that nearly every metro area saw an increase in its older adult population, with Eagle Pass, TX, being a rare exception.

Why the Southeast?

So, why are older adults flocking to the Southeast? It’s not rocket science. Warm weather, lower taxes, and affordable housing are big draws. But there’s more to it. Many retirees are moving closer to family or seeking communities with established amenities for older adults. Florida metros like Lakeland-Winter Haven have seen total population growth of over 20.65%, driven largely by retirees. Recent analysis shows that this trend is reshaping local economies, with increased demand for healthcare services and housing.

But it’s not just Florida. North Carolina’s metros are also seeing significant growth in their 65+ populations. Raleigh-Cary, for example, has become a magnet for retirees who want access to urban amenities without the high costs of traditional retirement destinations like New York or San Francisco. As the nation ages, these metros are becoming key players in the demographic landscape. This shift has implications for everything from healthcare funding to labor markets.

What’s Next for These Metros?

Looking ahead, the Boomer Belt will continue to grow. But what does that mean for these metros? For one, local governments will need to invest in healthcare infrastructure. Retirees also tend to vote at higher rates, which could shift local politics. And let’s not forget the economic impact. Older adults spend differently, prioritizing healthcare and leisure over housing and education. This creates opportunities for businesses that cater to retirees.

The Bigger Picture

What’s happening in the Boomer Belt is part of a larger trend. The US is aging, and metro areas are bearing the brunt of this demographic shift. This isn’t just a Southern phenomenon; it’s a national one. Updated Census data shows that older adults are moving to metros across the country, reshaping local economies and politics in the process.

So, what does this mean for the future? For one, policymakers need to take these trends seriously. Aging populations require targeted investments in healthcare, transportation, and housing. And businesses need to adapt to changing consumer needs. Whether you’re a policymaker or a business leader, understanding these demographic shifts is key to staying ahead of the curve.
