NJ’s population story is more complicated than the headlines suggest

Everyone assumes New Jersey is bleeding residents everywhere, all at once. The real picture is more complicated, and more specific, than that.

Start with the number most people get wrong: New Jersey's total population is not shrinking. It has grown for four straight years running, reaching an estimated 9.55 million people by July 2025 — up 41,861 residents in that single year alone, one of the ten largest numeric gains of any state in the country. That is real growth, not a rounding error.

What is true, and what drives every conversation about people leaving, is that New Jersey continues to lose more residents to other states than it gains from them — domestic migration, specifically. That loss just happens to be more than covered by two other forces: births outpacing deaths by about 26,000 in the most recent year, and international migration bringing new residents in from outside the country. Overall population growth and out-migration are both real. They are just two different numbers, and it matters which one you are talking about.

Ocean County's growth has a specific explanation

Ocean County had the largest population gain of any county in New Jersey last year, adding 5,351 residents. But before reading that as "people are choosing to stay," it is worth understanding where that growth is actually coming from.

The overwhelming majority of it traces back to Lakewood Township and its Orthodox Jewish community. Lakewood's population exploded roughly 45 percent between 2010 and 2020 alone, driven by one of the highest birth rates in the world — more than 5,000 babies born there in a single recent year, more than double the number in Newark, a city with twice Lakewood's population. As housing filled up in Lakewood itself, families began moving into neighboring Jackson, Toms River, Brick, and Howell, pushing Ocean County's growth numbers up across the board.

This is a genuine, remarkable demographic story. It is not, however, evidence that New Jersey's affordability problem is reversing itself, or that longtime residents are suddenly deciding to stay put. It is one specific, fast-growing community whose math simply works differently than most.

Cape May County stood alone

Here is the number that actually surprised me. Cape May County was not just the county that lost the most residents last year. It was the only county in all of New Jersey to lose population at all. Every other county in the state grew between 2024 and 2025. Cape May, alone, shrank — down 704 residents, a 0.7 percent decline.

That tracks with what those of us who love the Shore already understand instinctively. Cape May's economy runs on tourism and seasonal housing. A huge share of its housing stock is second homes and short-term rentals rather than year-round, affordable family housing. A county built that way can be packed all summer and still lose full-time residents every single year, because there is nowhere reasonably priced for a young family to actually live there full time.

What this actually tells us

New Jersey is not one uniform story right now. It is a state gaining population overall, losing residents specifically to other states, growing explosively in one demographic community that has almost nothing to do with the broader affordability conversation, and shrinking in exactly one county built entirely around seasonal tourism.

The frustration behind the "New Jersey is losing people" headlines is still real and still worth taking seriously — high property taxes and housing costs really are pushing longtime residents, especially retirees, toward other states. That story has not gone away. It is just one thread in a much more complicated fabric than a single headline number can capture.
