Child-Raising Costs in Some Cities Becoming Too High for Many U.S. Families

According to a new Zillow report, New York City currently has the lowest number of families with young children in the past two decades. The reality is that raising a family in the most expensive cities in America has become financially unfeasible for numerous families. In cities like San Francisco, Boston, and San Jose, CA, the annual expense for a single child now exceeds $40,000, with the majority allocated to child care.

This is a concerning trend, not only because it highlights the growing divide between the wealthy and the rest of the population. Extensive research conducted by Harvard’s Opportunity Insights, under the direction of economist Raj Chetty, has identified the key factors that provide a child born into poverty with the best chances of upward mobility. Surprisingly, it is not merely the availability of jobs or a low local poverty rate that matters most.

The primary determinant is the child’s environment, specifically growing up among individuals who are more affluent than their own family. Chetty’s team refers to this phenomenon as “economic connectedness,” which they have found to be the most significant predictor of mobility.

A low-income child raised in a diverse community tends to earn approximately 20% more as an adult compared to one raised in a segregated environment. Urban areas, with their shared educational institutions, transportation systems, and public spaces, are particularly effective at facilitating interactions among various economic classes.

However, this diversity is the first aspect a city sacrifices when it becomes unaffordable for the middle class. As families situated between the wealthy and the impoverished vanish, the daily interactions across different income levels diminish, along with the very elements that made urban living a pathway to success. Children who remain in such environments face diminished prospects for upward mobility, and the schools, local employment opportunities, and community engagement that families foster begin to decline. The result is a city that becomes wealthier, older, and less capable of rejuvenating itself.

Families Priced Out, Americans Seeking Affordable Areas

New York City serves as a prominent illustration of this trend. The proportion of households with children under 18 in New York decreased to 35.5% in 2024 from 46.3% in 2005, as per a StreetEasy analysis of Census Bureau data, indicating that families departed New York at a faster rate than any other city in the United States.

Two primary expenses are driving families away: housing costs and child care. Both of these factors disproportionately affect parents of young children, and they have escalated simultaneously. According to the StreetEasy Rent Index, asking rents throughout the city have increased by over 20% since 2019. Child care costs have surged even more dramatically.

In 2024, the average cost of home-based care for an infant or toddler reached $18,200 annually, marking a 79% increase over five years, while center-based care reached $26,000. During the same timeframe, local inflation was recorded at 20%, while wages only rose by 13%.

In numerous neighborhoods, the combined cost of a year’s rent and a year’s child care, excluding food and utilities, already matches the entire median income of a local family with children. Federal guidelines suggest that child care expenses should not exceed 7% of a family’s income. However, a New York family would need to earn approximately $334,000 to afford center-based care for one toddler, which is four times the median family income in the city.

Many families that remain are those who can manage these costs. According to the city’s comptroller’s office, middle-income families are disproportionately represented among those who have left New York, as they earn too much to qualify for subsidized care yet too little to comfortably handle an $18,000 expense per child. Consequently, the social fabric that connects various societal classes is deteriorating.

Zillow’s research indicates that by mid-2025, only 11 major U.S. markets remained affordable for a median-income buyer, a significant decrease from 39 five years prior. When a child care expense is added to a mortgage that is already unaffordable, the additional cost effectively renders the first one unattainable.

Zillow has consistently maintained that cities must focus on providing affordable housing for families. Current construction trends favor studios and one-bedroom apartments, while the two- and three-bedroom units that families require are the most challenging to build due to outdated zoning laws. San Francisco has begun to tackle this issue by enacting a Family Zoning Plan in December, which permits the development of more mid-sized buildings in its western and northern neighborhoods—homes that families can grow into rather than out of.

Whether other cities will emulate San Francisco’s approach will determine a question that transcends any individual housing market. A city that accommodates only those with financial means may still function well as a tourist destination, an investment hub, or a temporary residence. However, what remains uncertain is whether America’s premier cities intend to remain places where an average family can establish roots. If this changes, it could jeopardize the opportunity for countless children to surpass their parents’ achievements.
