If you’ve ever driven up the I-87 toward Canada, you’ve probably seen the signs for Plattsburgh. It’s that curious lakefront city where the street signs are sometimes in French and the lake is so big it feels like an ocean. But lately, there’s been a lot of chatter about the population of Plattsburgh New York and whether this "Little Montreal" is actually growing or slowly shrinking into the Adirondack landscape.
Honestly, the numbers are a bit of a rollercoaster.
As of early 2026, the city proper is home to roughly 19,758 people. That might sound small if you’re coming from Albany or the City, but in the North Country, Plattsburgh is the big fish. What’s wild is that while the city itself has seen a tiny dip—down about 0.4% since the 2020 Census—the vibe on the ground feels completely different. You’ve got new luxury apartments popping up near the old Air Force base and a downtown that’s trying its hardest to become a walkable hub.
Is the Population of Plattsburgh New York Actually Shrinking?
It depends on who you ask. If you look strictly at the Census Bureau’s "city" data, you’ll see a slight downward trend. In 2020, the count was 19,839. Now, we’re looking at a 2026 estimate that’s shaved off about a hundred residents.
But here’s the kicker. The city is only five square miles.
Most people who say they live in Plattsburgh actually live in the Town of Plattsburgh, which wraps around the city like a donut. When you combine the city, the town, and the surrounding suburban sprawl, the "urban area" holds closer to 31,000 people.
Why the numbers feel "off"
- The College Factor: SUNY Plattsburgh is the heartbeat of the town. When 4,000+ students are in session, the city feels packed. When they leave for the summer? It’s a ghost town.
- The Canadian Connection: On any given Saturday, half the people in the Target parking lot have Quebec license plates. They don’t count toward the population of Plattsburgh New York, but they drive the economy.
- Migration Shifts: Since 2021, about 16% of residents are new to their homes. People are moving in from places like Burlington, Vermont, where the rent has become absolutely astronomical.
The Age Gap: A City of Young Adults and Retirees
If you walked down Margaret Street today, you’d notice something immediately. There are a lot of twenty-somethings.
The median age in Plattsburgh is surprisingly low—about 29.5 years old. Compare that to the rest of New York State, where the median is closer to 40, and you realize how much the university influences the local stats. Roughly 19% of the population falls into the 20-to-24 age bracket.
But it’s not all Gen Z and Millennials. There’s a growing "silver" population too. About 16% of residents are over the age of 65. This creates a weird demographic tension. You have a massive group of people who want craft breweries and bike paths, and another group that is more concerned with property taxes and hospital access at CVPH (Champlain Valley Physicians Hospital).
What’s Keeping People There (And What’s Pushing Them Out)
Let’s talk money. The median household income is hovering around $53,962. That’s not huge, especially when you consider that the cost of milk and gas in the North Country is often higher than in the suburbs of Syracuse.

Poverty is a real issue here. Roughly 24.2% of the population lives below the poverty line. That’s a heavy number for a city this size. It's often linked to the decline of old-school manufacturing, though the city is desperately trying to pivot into "transportation equipment manufacturing" with companies like Alstom and Nova Bus.
The Housing Crunch
You’d think in a small city, housing would be easy to find. Nope.
The median sale price for a home in Plattsburgh hit $302,000 in late 2025. That’s a 41% jump in just a few years. If you’re a local making $18 an hour at a retail spot, buying a house feels like a fever dream. This "Burlington-ification" of Plattsburgh is a double-edged sword. It brings in wealthier remote workers, but it’s squeezing out the people who have lived here for generations.
The 2026 Outlook: What Most People Get Wrong
People often think the population of Plattsburgh New York is destined to decline because it's "too far north."
That’s a mistake.

The city just got designated as a "Pro-Housing Community" by the state. This opens up millions in funding for new apartments and infrastructure. They aren't just waiting for people to show up; they’re building for them. There's also the massive "Empire AI" initiative and various North Country economic grants aimed at turning this area into a tech corridor between Montreal and Albany.
Basically, Plattsburgh is in a transition phase. It's moving away from being just a "college town" or a "border town" and trying to become a legitimate small-scale metro.
Real Steps for Moving or Investing in Plattsburgh
If you're looking at these population trends because you're considering a move or an investment, don't just look at the raw numbers.
Check the Town, not just the City. If you want more space and lower taxes, the Town of Plattsburgh (outside city limits) is where the growth is actually happening. The city is great for walkability, but the town is where the new construction is booming.
Watch the vacancy rates. Rentals are incredibly tight. If you’re moving for a job at the hospital or the university, start your search at least three months in advance. The student cycle means that most leases open up in June and August.

Look at the "Lake Effect." Property values near Lake Champlain are insulated from the broader market dips. Even if the general population of Plattsburgh New York stays flat, the waterfront is always going to be a premium asset.
Keep an eye on the 2026 mid-year census updates. While the city's official count might stay around 19,000, the diversity and economic output of the region are moving in a much more interesting direction than the flat numbers suggest.
