Among the 40 largest metros in the country, every single one grew last year—except Pittsburgh, almost. What held us on the right side of zero was the Haitian immigrant community settling in Charleroi and the Mon Valley.

Chris Briem, a regional economist who follows Pittsburgh closely, published a chart showing this data. Among the top 40 metros by population, every one added people last year. Pittsburgh was the near-exception. The metro gained population—modestly, barely measurably—because of immigration. Without the influx of Haitian families settling in towns like Charleroi, Monessen, and other Mon Valley boroughs, Pittsburgh would have shrunk.

What's Happening in Charleroi

In Charleroi specifically, you can see it. More bicycles outside apartment buildings. The public library busier than it's been in years. Classrooms filling up. A community that had been hollowed out is getting energy back. Families are moving in. Kids are being born. People are starting small businesses. A deli that had minimal foot traffic is suddenly serving the community. Storefronts that were empty now have faces in them.

This isn't abstract economic data. This is people choosing to build lives in a place. They're not moving to Pittsburgh proper. They're moving to Charleroi because the housing is affordable and the community is real. They're choosing the Mon Valley deliberately, even though it's not a trendy destination. They're choosing it because it makes sense—because they can buy a home, because there's community there, because it's a place where you can actually live, not just exist as a renter.

The National Pattern

The U.S. grew 0.5 percent last year. Without immigration, that number would have been flat or negative. The entire growth story for American metros is immigration. People moving from other countries, seeking opportunity, choosing to build lives here. That's driving everything. Without it, most of the country would be stagnant or contracting.

Pittsburgh is no exception. The growth line that kept us from shrinking is immigration. The source just happens to be concentrated in the Mon Valley. Haitian families, primarily. People with skills, work ethic, and the determination to build something in a place that had been written off.

The Sunbelt Boom—and Its Costs

Meanwhile, the Sunbelt metros are booming. Orlando grew 2.5 percent. Houston, Dallas, Charlotte, Miami—all adding people at rates that dwarf Pittsburgh's. Sun, jobs, lower taxes, remote workers migrating south. The narrative around regional growth has been tilted toward that story for years. Move to a growing metro, we're told. The future is there.

But growth has costs. Rents in Orlando, Austin, Miami are skyrocketing. Traffic is becoming unbearable. Infrastructure is being overwhelmed. Schools are overcrowded. The growth is real, but it's creating chaos and pricing out the people who are already there. You can't afford to live in a place that's booming because the boom itself drives costs up.

Pittsburgh isn't booming. But that's actually an advantage. We're not buckling under growth pressure. Our bones are old and strong. Housing is still within reach. There's room to do things differently. The Haitian families moving to Charleroi aren't being priced out. They're building real equity. They're not renting—they're buying homes, starting businesses, planting roots.

The Significance

The fact that Pittsburgh didn't shrink matters more than the numbers suggest. A region that stops losing people has stopped the death spiral. It means the market is stabilizing. It means there's enough economic activity and livability to attract people from outside, even without the marketing hype of a booming destination.

And the source of that stability—Haitian immigrants in the Mon Valley—is exactly the kind of grounded, practical population growth that builds real community. These are people with nowhere else to go but forward. They're not speculating. They're not looking for the next trend. They're making a commitment to a place and doing the work.

Pittsburgh stayed on the growth side of zero because people believe Pittsburgh is worth building a future in. Not because we're trendy. Not because of venture capital or tech hype. Because we're affordable, because we're real, and because there's work to do and community to be part of.

That's stability. That's worth paying attention to.
