Faster New Jersey cost growth shrinks the $12,000 suburban discount for NYC families
Living Wage Institute data show New Jersey family budgets up about $40,800 since 2021, rising 6.7% a year against Manhattan's 4.6%. At that pace the roughly $12,000 a family of four still saves across the Hudson is gone within five years.

What happened
- Hudson County, which includes Hoboken and Jersey City, has seen family budgets rise 9.1% a year since 2021, the fastest of any US county with at least 100,000 residents.
- New Jersey suburbs make up eight of the 20 large US counties where family budgets have grown fastest since 2021.
- Kristyna Frantz moved from Washington Heights to Fanwood in 2024 after having twins and now pays $5,000 for child care for three children; her eldest had a free city place.

Why it matters
- decision For NYC-paid parents weighing the move, the comparison now turns on how many years of paid child care lie ahead, because one family's child-care penalty can equal the whole average saving.
- constraint A family that buys in New Jersey to save money is buying into costs growing about two points a year faster than Manhattan's, so if those rates hold the saving is largest on the day of purchase.
- cost Each free program New York adds, with 2-K now being rolled out, raises New Jersey's relative cost on the line where it already loses most.
On the Living Wage Institute's numbers, Manhattan is still dearer: a two-earner family with two children needed $135,538 of after-tax income there in 2026, against $123,676 on the New Jersey side [1]. The difference is $11,862, about 8.8% of the Manhattan figure [21][22]. Bloomberg's report gives the $123,676 number in a passage about Hudson County and does not say whether it is the county or the state.
The gap narrows because New Jersey budgets have grown 2.1 percentage points a year faster than Manhattan's, 6.7% against 4.6% [24]. Compound both 2026 figures at those rates and they meet in about 4.6 years, in 2030 or 2031 [25]. At Hudson County's 9.1% they meet in a little over two [26]. Both projections extend five years that began with a pandemic jump in housing prices [19], and every county in the state has outrun the 4.5% national median over that stretch [3].
Child care is where the average misleads. Hudson County's care runs about $5,200 a year above the city's [8], where free pre-K and 3-K are open to every income level [9]. Frantz figures the city would cost her $1,000 a month less for child care alone [11]. Over a year that is $12,000, roughly LWI's whole Manhattan gap, before her commute or her mortgage [23].
"At this phase, it's more expensive for us to raise kids in New Jersey than New York," she said. "We're paying more in child care, commuting costs and our mortgage is more than our rent in the city." [12] "For many young families living in New Jersey today, child care is their biggest expense," said Sharon Levine, campaign director at the advocacy group Start Strong NJ [18].
Some of the pressure comes from people making the same move. Misael Galdámez, a researcher at LWI, said an influx of new residents has added to costs [13]. Almost 57,000 people moved to New Jersey from New York state between 2023 and 2024, according to Census data compiled by USA Facts [14]. "Places that were more affordable have started to see their costs increase," Galdámez said [15]. Since 2023, growth in the state's child-care and healthcare costs has more than tripled [6].
The projection can fail in two ways. Home-price increases across New Jersey have slowed since the pandemic [16], and if state budget growth falls back to Manhattan's 4.6%, the 8.8% gap stops narrowing. The child-care penalty also depends on children's ages. Frantz wished for universal care for all three children so the family could "just pay for after-school care" [20].
I think the discount survives in 2026 for the average two-earner family, at about $12,000 a year, and is already gone for a household paying for young children's care. If LWI's next figures show New Jersey growing at Manhattan's rate, the first half of that view holds and the five-year projection is wrong.
What to watch
- Whether New Jersey widens eligibility for child-care tuition assistance to more working parents and students, as Start Strong NJ is pushing.
- Home prices in New Jersey towns with quick train access to Manhattan, which kept rising after statewide gains slowed.
- How fast New York's 2-K rollout reaches families, since it extends free care on the line where New Jersey is already dearer.
