A childcare desert is a place where there are more than three young children for every licensed childcare slot. The Center for American Progress created that definition, and it is a supply measure, not a price measure. A neighborhood can sit comfortably outside desert territory and still price every local family out of the care that exists. The metric answers one question only: are there enough licensed places for the children who live here.

Where the term came from

The Center for American Progress borrowed the framing from food deserts and published the first quantitative version in a report called Mapping America’s Child Care Deserts on August 30, 2017. That original definition described neighborhoods or communities either lacking any childcare options or having so few providers that more than three children exist for every licensed slot, applied at the census tract level.

The threshold has stayed at three to one across every version since. The geography has not.

The current measure, published in 2026 using 2025 data, drops census tracts entirely. It defines a family as living in a childcare desert if they reside in a location with more than three local young children under age six per local licensed slot, calculated using continuous distances between families and providers rather than tract, ZIP code, or county boundaries.

That change matters more than it sounds. Tract boundaries are arbitrary lines that can put a family two blocks from a provider on the wrong side of a statistic, or credit them with a center they would need a car and forty minutes to reach.

How many people live in one

The Center for American Progress reported in April 2026 that 46 percent of U.S. children under age six lived in a licensed childcare desert in 2025, down from 51 percent in 2018. The analysis covers all states and the District of Columbia, with population figures drawn from the Census Bureau’s American Community Survey five-year estimates for 2019 through 2023.

Nearly half the country’s youngest children, and an improvement over seven years earlier. Both things are true.

State variation is extreme. Alaska stood at 96 percent, Hawaii at 95 percent, and Idaho at 83 percent. At the other end, the District of Columbia came in around 5 percent, Massachusetts around 21 percent, and New Jersey and Nebraska just above 25 percent.

A family in Anchorage and a family in Boston are living in different countries as far as this measure is concerned.

The one category that got worse

Remote rural areas moved from roughly two-thirds in 2018 to 70 percent in 2025. Every other grouping improved or held. Distance is the binding constraint in places where a licensed center needs enough enrolled children within driving range to cover its staffing costs, and rural population density does not supply them.

Who else is disproportionately affected

The same Center for American Progress analysis found that among children under six living in poverty, 43.5 percent were in a desert. In majority-Hispanic and Latino communities the figure was 52.2 percent. In majority-Black non-Hispanic communities it was about 35 percent.

Head Start supply is scarce almost everywhere by this standard. Measured against the same three to one benchmark, the Center for American Progress found 99.7 percent of urban areas and 96.7 percent of rural areas qualified as Head Start deserts.

The same analysis notes that nearly 70 percent of children under six live in households where all parents are employed. The demand is not hypothetical.

What the metric deliberately excludes

Understanding the limits is the difference between using this number and misusing it.

It counts licensed slots. License-exempt providers, relatives, nannies, and informal arrangements are invisible to it, and those arrangements cover a large share of American childcare. A community with thin licensed supply and a dense network of family care is not experiencing what the label suggests.

It says nothing about price. A slot you cannot afford counts identically to one you can. Child Care Aware of America put the national average annual price of care at $13,184 in 2025, with center-based infant care in the range of $15,015 to $15,728 depending on method. A neighborhood well supplied at those prices is not a solved problem for a household earning the median.

It says nothing about hours. Most licensed centers operate on a standard weekday schedule. Parents working nights, weekends, or rotating shifts face a supply problem the ratio does not detect.

It says nothing about quality, age fit, or vacancy. A slot in an infant room does not help a family needing toddler care, and a slot that exists on paper may have a nine-month waiting list.

Read strictly, the measure tells you whether licensed capacity has kept pace with the child population in a given place. That is genuinely useful and it is all it is.

Why supply thins out

Licensing rules set staff-to-child ratios, which fixes the minimum number of adults a program must employ and puts a floor under its costs. Infant ratios are the tightest, which is why infant rooms are the first thing a struggling center closes and the last thing a new one opens.

The workforce those rules require is paid near the bottom of the wage scale. The Bureau of Labor Statistics reported a median wage of $16.82 an hour for childcare workers in May 2025, or $34,980 a year, against $24.51 an hour and $50,980 across all occupations. BLS projects childcare employment will decline about 2 percent between 2025 and 2035, against 3 percent growth across all occupations.

A sector cannot expand capacity while shedding workers. The desert map is downstream of a labor market that does not pay enough to staff the rooms.

How to use the number

Treat a desert designation as a signal about capacity and then ask the three questions it cannot answer. What does care cost here relative to local incomes. Does supply match the hours people actually work. Is there licensed capacity for the specific age that needs care.

A place can fail on all three while sitting outside the desert threshold. That is not a flaw in the metric so much as a reason not to let one metric carry an argument by itself.

Fight For A Living Wage, a nonpartisan grassroots 501(c)(3), argues that affordability is the accurate frame for problems like this one, spanning housing, healthcare, childcare, food, transport, education, and retirement together rather than any single category alone. Childcare deserts illustrate why the distinction is not academic. Building more slots addresses the supply half. It does nothing about a price that already exceeds college tuition in most states, or a wage that keeps the rooms understaffed.
