Since 2020, nearly three-quarters of the population lost across every shrinking city in metro Atlanta has come from just three suburbs, and none of them are struggling markets. If you’re weighing where to buy among Atlanta’s neighborhoods and suburbs, the fastest growing Atlanta suburbs right now are not the ones you’d expect, and the reason the popular ones are shrinking has nothing to do with home values or school quality.
When I filmed this in September 2026, I pulled Census Bureau numbers to find out what’s actually going on, because on the surface it doesn’t add up. Metro Atlanta has added over 361,000 people since 2020. So why would three of its most popular suburbs be losing population at the same time?
I’ll walk through which suburbs are shrinking, which ones are exploding, and what the shift actually means if you’re relocating to Atlanta and trying to figure out where to buy.
The Three Suburbs Losing People
Out of the 151 cities that make up metro Atlanta, 24 have lost population since 2020. Nearly three-quarters of that total loss has come from three cities: Sandy Springs, Johns Creek, and Roswell.
- Sandy Springs is down roughly 3%, a loss of just over 3,200 people.
- Johns Creek is down 2,178 people, about 2.6%.
- Roswell is down 1,444 people, about 1.6%.
Here’s what makes that strange: these are three of the most expensive suburbs in the metro, and home values in each one rose between 46% and 53% over the same period. They are not distressed markets by any definition.
I went in assuming one of two things: either these areas weren’t building enough new homes to keep up with demand, or they’d simply priced themselves out of reach. Neither one held up. Building had nothing to do with it, and as you’ll see below, the areas absorbing the growth aren’t cheaper either. Schools are highly rated in both the shrinking suburbs and the growing ones, and there’s no meaningful difference in median lot size between them.
Why They’re Actually Emptying Out
These suburbs didn’t really empty out. They aged in place.
The families who bought in Sandy Springs, Roswell, and Johns Creek in the ’90s and 2000s are, for the most part, still there. Their kids just grew up and left, and the households behind them got smaller instead of turning over to new buyers.
- Sandy Springs has gone from 2.29 people per household to 2.05.
- Johns Creek and Roswell both saw similar reductions in people per household.
- Johns Creek’s median age has risen three years over the same window.
To put a number on how sharp that shift is: around 2018, Sandy Springs and Cumming had nearly identical average household sizes. Five years later, Sandy Springs sits at 2.05 people per household while Cumming is at 2.77. Same houses, fewer people in each one. Vacancy rates in Sandy Springs have actually gone down over that time, so the homes aren’t sitting empty. They just hold smaller families than they used to.
The Three Suburbs Exploding in Growth
While Sandy Springs, Roswell, and Johns Creek were shrinking, the families who would have replaced their kids’ generation went north instead. The three fastest-growing cities in metro Atlanta are:
- Cumming, in Forsyth County, up a staggering 69% since 2020, including 23.6% in the last year alone. Nearly one in five people living in Cumming today did not live there twelve months ago.
- Braselton, up nearly 36%.
- Dacula, in Gwinnett County, up 35.2%.
Canton deserves an honorable mention too. It only grew about 22% since 2020, a smaller percentage than the three above, but because it started from a larger base, it actually added more people in raw numbers than Cumming did: nearly 7,400 new residents.
These aren’t cheaper alternatives, either. Forsyth County is the most expensive county in metro Atlanta, so nobody moving to Cumming is running from cost. And these exploding suburbs didn’t just grow, they got younger. Cumming’s median age was 42.6 in 2018. Today it’s 37.8, nearly five years younger than it was.
The Real Reason: Nobody’s Commuting Five Days a Week Anymore
Newer homes have always been available further north, so the age of the housing stock alone doesn’t explain why buyers only recently started choosing it. What changed is remote work.
Canton’s typical home is 15 years newer than Roswell’s. Homes in Braselton run about 21 years newer than those in Sandy Springs. Two-thirds of Canton’s housing supply was built this century, compared to less than a quarter of Roswell’s.
That age gap has always existed. What’s different is that 263,000 metro Atlanta workers worked from home in 2019, and by 2024 that number had grown to 614,000. That increase alone is bigger than the combined population of the three shrinking suburbs. Forsyth County had the highest work-from-home rate in the metro in 2024, at 28.2%.
Sandy Springs, Roswell, and Johns Creek have historically commanded a premium because they sit roughly 25 minutes or less from the perimeter or Midtown. That premium made sense when someone was making that commute ten times a week. It makes a lot less sense when they’re only making it twice a week, and an extra 30 minutes on the two days that matter buys them a home built in 2005 instead of 1989.
None of this means North Fulton got worse. If anything, it’s gotten better in plenty of ways. It’s that the thing it was charging a premium for, proximity to the office, stopped being worth as much to as many buyers.
What This Means If You’re Choosing a Suburb
If you’re weighing Roswell against a suburb further north, or working through the wider buying process, a few things from this data are worth knowing going in.
Roswell, Sandy Springs, and Johns Creek are still outstanding places to live. But you’re buying into a market with limited inventory and an older housing stock, so budget for updates and be comfortable with an older home. Older doesn’t automatically mean worse. I’ve seen plenty of these homes thoroughly renovated and well maintained enough to rival new construction in quality and reliability. Don’t cross a home off your list over its age alone until you know the actual condition of its major systems.
If you look further north instead, in Forsyth, Gwinnett, or Cherokee County, you’ll likely land a newer home, but don’t expect to save much money doing it. Resale homes in these northern suburbs are also taking nearly twice as long to sell, because they’re competing against builders offering incentives on brand-new construction that a resale can’t match. That should only really factor into your decision if you’re planning to be there for less than three years.
Commute is the first thing I tell every relocating client to figure out, and it’s still the right starting point. From there it comes down to schools, budget, and the kind of home and lifestyle you actually want, weighted however matters most to your situation. If you don’t have a commute to plan around, the home’s own characteristics carry more of the weight.
The Bottom Line
Sandy Springs, Roswell, and Johns Creek didn’t get worse. They aged in place while the families who would have replaced them found more house for the money a little further north, and remote work made that trade easier to make. Metro Atlanta is likely to keep growing steadily over the next decade or two, and which suburbs keep exploding and which start to empty out will keep coming down to whether their value proposition still matches what people are willing to pay for.
