For years, the move was obvious: keep the New York City paycheck and hop over to New Jersey to lower your bills. That math is getting messy. The Living Wage Institute says the annual budget needed for two working adults and two kids in New Jersey is up about $40,800 between 2021 and 2026, a 6.7% yearly increase.
The institute - organized as a nonpartisan public benefit corporation that monitors expenses such as housing, child care, food, transportation, and healthcare - reports that every New Jersey county is beating the 4.5% national median growth. And looking at U.S. counties that each have 100,000 or more residents, the places with the fastest-rising family budgets since 2021 include 20 such counties, eight of which are in New Jersey's suburbs.
Home prices that took off during the pandemic lit the fuse. While statewide price gains have cooled, towns with quick train rides to Midtown kept climbing as more employers called people back. That has tightened the gap between city and suburb. Over the past five years, family expenses in Manhattan rose 4.6% a year, and many New Jersey suburbs are now accelerating past that.
Since 2023, increases in child care and healthcare costs in New Jersey have more than tripled, which has pushed family budgets higher. In Hudson County, child care averages $37,242 a year, about $5,200 more than in New York City. NYC's free pre-K and 3-K programs, open to all income levels, help blunt the hit, and the city is adding a 2-K program.
"Places that were more affordable have started to see their costs increase," Misael Galdámez, a researcher at the Living Wage Institute, said. He also points to more people moving in. New Jersey's population has been edging up since 2023; nearly 57,000 moved from New York State during 2023 to 2024, per Census data that USA Facts compiled.
"For many young families living in New Jersey today, child care is their biggest expense," sometimes topping the mortgage or rent, said Sharon Levine, who leads the campaign for Start Strong NJ, a child care advocacy organization. The advocacy group is pressing the state to expand tuition-assistance eligibility to additional working parents and students.

Ask Kristyna Frantz. She and her husband lived for ten years in a three-bedroom in Washington Heights, then moved to Fanwood, New Jersey, in 2024, soon after she gave birth to twins. The help from nearby in-laws is real, but so is the bill: $5,000 a month for child care for their three children.
In the city, their oldest had a free spot in a public program. By her tally, child care alone would be $1,000 less each month if they had stayed in NYC, and that does not include the lunches she now packs.
"At this phase, it's more expensive for us to raise kids in New Jersey than New York," she said.
Hudson County shows how fast things are moving. Family-sustaining budgets there have risen 9.1% per year since 2021, the quickest pace among U.S. counties with at least 100,000 residents. Even with that, the overall cost to support two working adults and two children in New Jersey in 2026 is still lower than Manhattan: $123,676 after tax versus $135,538.
Scott Paer and his wife left a two-bedroom in Manhattan for Westfield, New Jersey, in 2025 to get more room for their toddler. They were outbid on 11 homes in commuter towns before finally purchasing in Union County, roughly 25 miles outside the city. "We certainly didn't save any money," he said. "We spent more," largely because of the mortgage and other ownership costs.
Or as real estate economist Jeffrey Otteau puts it: it used to be that families could put down roots anywhere in New Jersey and make the numbers work. Today, for households earning $150,000 or less, it is not the affordability refuge it once was. If you are weighing a move or child care changes, the takeaway is simple: map your actual line items.
Child care can outrank housing, commuting is back in play, and healthcare is not standing still. The better you know your real costs, the fewer surprises hit your monthly cash flow.
