According to U.S. Census Bureau demographer George M. Hayward, when international arrivals to a large county slow down, "population growth diminish[ed] or even turn[ed] into loss." He was describing a national pattern. He could have been describing Dallas County specifically.
On March 26, 2026, the Census Bureau released its newest county-level population estimates, covering the twelve months from July 2024 to July 2025. The headline for North Texas looked great: the Dallas-Fort Worth metro added more than 120,000 people, the second-largest numeric gain of any metro area in the country, trailing only greater Houston. If you've been reading real estate coverage of this region for the past few years, that's the number you'd expect.
Buried in the same report was a second number that got a lot less attention. Dallas County, the largest county in the region and home to the city of Dallas itself, didn't grow at all. It shrank, falling from 2,664,013 residents to 2,661,397, a loss of 2,616 people. That's enough to rank Dallas County ninth among all population-losing counties in the United States for the year.
So the region grew by six figures. Its anchor county lost people. Both of those things are true at the same time, and understanding why matters if you're currently comparing a home search inside Dallas against one out in Kaufman County.
How a Growing Region Produced a Shrinking County
The short version is that Dallas County's population math has depended on immigration more than most people realized, and that input just got cut sharply.
For years, net international migration into Dallas County offset a steady stream of people moving out to other parts of the country, mostly to the suburbs ringing the city. When immigration slowed, that offset disappeared. According to reporting from the Dallas Observer, net international migration into Dallas County fell 52% between July 2024 and June 2025 compared to the year before, a drop tied to reduced border crossings and stricter enforcement during that period.
Take away the immigration cushion and what's left is the underlying domestic trend, which was never flattering for the county. A Dallas Morning News opinion analysis found that net domestic out-migration subtracted 1.7% from Dallas County's population between 2024 and 2025 alone, and that a net 197,000 residents, roughly 7.5% of the county, moved away between 2020 and 2025. That out-migration rate was the second-worst of any of the 100 largest counties in the country over the 2024-2025 period, behind only Miami-Dade.
This isn't a Dallas-only story. The same Census release showed that counties with a million or more residents lost a combined 637,634 people to domestic migration nationwide in 2024-2025, while mid-size and smaller counties gained. Big urban counties import residents from abroad and export them to smaller counties nearby. When the import side slows, the export side is what's left standing.
What the Numbers Look Like Side by Side
| County | 1-Year Change (Jul 2024–Jul 2025) | Direction | National Standing |
|---|---|---|---|
| Dallas County | −2,616 residents | Lost population | 9th-largest numeric loss in the U.S. |
| Collin County | +42,966 residents | Gained population | 2nd-largest numeric gain in the U.S. |
| Kaufman County | +11,000+ residents (nearly 6% growth) | Gained population | 3rd-highest growth rate in the U.S. |
Collin County, home to Plano and Frisco, grew by 3.4% in a single year and now sits close to 1.3 million residents, according to Census figures reported by CultureMap Dallas. Kaufman County's growth rate outpaced that on a percentage basis, adding more than 11,000 people for a growth rate near 6%, the third-highest of any county in the country for that period.
Put plainly: the people leaving Dallas County aren't disappearing. A meaningful share of them are landing in the two counties on either side of it.
The City Inside the County Isn't Rebounding Either
It's worth separating the city of Dallas from Dallas County, since they're not the same thing and the city's own trajectory has been flat for longer than the county's recent dip. The city's population began sliding in 2018 and, even with a slight recovery between 2020 and 2024, still hasn't returned to that 2018 peak. Dallas is more dependent on immigration than the rest of the region for its growth, since new immigrants disproportionately settle inside core cities rather than the suburbs around them. That dependency is exactly what makes the city vulnerable when immigration levels shift the way they did in 2025.
None of this means every part of Dallas is losing appeal at the same rate. Analysts have pointed out that the city contains both large stretches of modest, older housing stock in its southern and eastern sectors and considerably higher-priced neighborhoods in the north, and that closer-in neighborhoods with tighter supply have generally held their value better than the citywide numbers suggest. The population trend is regional and structural. It doesn't erase block-by-block differences.
What Softer Growth Looks Like on a Listing Sheet
Population data eventually shows up in showing traffic and offer counts, and the current numbers for Dallas are consistent with a county that's cooling relative to its own suburbs rather than one in crisis. Over the three months ending June 2026, homes in Dallas received an average of two offers and sold in around 41 days, a pace real estate data providers describe as "somewhat competitive" rather than red-hot. That's a meaningfully slower, calmer pace than the multiple-offer scrambles Dallas buyers dealt with a few years ago.
There's also a search-behavior signal worth noting. In the first quarter of 2026, roughly 17% of homebuyers searching within Dallas were looking to move out of the metro entirely, while the other 83% stayed within the broader DFW area, meaning most people leaving Dallas proper are relocating somewhere else in North Texas, not leaving the region altogether. That lines up with what the county-level migration data shows: the exits are largely internal, redistributing residents rather than sending them out of state.
Where the Movers Actually Landed
Kaufman County's growth isn't happening in a vacuum. It's connected to the exact dynamic playing out in Dallas County. As buyers get priced out of, or simply choose to leave, the urban core, they're finding more house for the money 30 to 40 minutes east, in communities like Terrell, Forney, and the smaller towns along US 175 and I-20. A Lowe's opening in Kaufman this past August, reported by the Dallas Business Journal, is itself a marker of that shift, since national retailers generally follow rooftops, not the other way around.
For someone actively comparing a Dallas listing against a Kaufman County listing, the population data changes the framing of that comparison. It's not simply "the suburbs are cheaper." It's that the demographic tide inside Dallas County has turned, at least for now, while Kaufman County is absorbing a share of that redirected growth at one of the fastest rates in the country. That's a different market to buy into than a county that's still gaining residents in the way the metro headlines imply.
A Few Questions Worth Asking Before You Assume Anything
Does a shrinking county mean Dallas home values are falling apart? No. A population dip of roughly a tenth of a percent isn't a collapse, and the data shows real neighborhood-by-neighborhood variation within the city. It does mean the demand pressure that used to support rapid price growth citywide has eased, which shows up as more moderate competition on individual listings.
Is this specific to Dallas, or is it happening everywhere? It's part of a national pattern. Census data shows large urban counties across the country losing residents to domestic migration in 2024-2025 while mid-size and smaller counties gained. Dallas County's experience is a local version of a trend playing out in big counties nationwide.
What does this mean if I'm choosing between Dallas and somewhere in Kaufman County right now? It means the population momentum currently favors Kaufman County, not Dallas proper. That doesn't make one choice objectively right, but it does mean a buyer should weigh commute reality, budget, and lot size against a growth trend that's actively running in Kaufman's favor rather than assuming Dallas's growth reputation still applies evenly across the whole metro.
