The Annie E. Casey Foundation released its 2026 KIDS COUNT Data Book this week — the 37th edition of the country's most-watched annual snapshot of child well-being. As an organization built around the earliest years, we read straight to the early-childhood numbers, and they are worth sharing with families plainly.
The headline that matters most for little ones
The number that stopped us: according to the 2026 KIDS COUNT Data Book, 54 percent of 3- and 4-year-olds are not enrolled in school — that is, not in preschool or pre-K. More than half of the children in the age range where early learning does its most important work are not in a formal early-learning setting. And the trend is the wrong direction: that figure has worsened from 52 percent in the 2015–19 period.
The report's broader education picture is sobering in the same way. It finds that 70 percent of fourth graders are not proficient in reading and 73 percent of eighth graders are not proficient in math, and that overall child well-being sits lower than it did in 2019, with education the domain dragging the index down.
What the number does and doesn't mean
A couple of honest caveats, because numbers like these can land harder than they should. First, "not enrolled in preschool" is not the same as "not learning." Plenty of three- and four-year-olds are home with a parent or relative who is reading, talking, and playing with them all day, and that is real early education. The data flags a gap in access to formal programs; it does not measure the love and learning happening in living rooms.
Second, this is national data describing a years-long trend, not a verdict on any one child or family. The Data Book is a tool for spotting where the system is falling short — and on early learning, it is falling short for a lot of children.
Why these years carry so much weight
The reason a preschool-enrollment number rates as front-page news is that the early years are not a warm-up. By kindergarten, the gaps that show up in later reading and math scores are often already present. Brain development, vocabulary, the back-and-forth of conversation, the social skills of sharing and waiting and trying again — these are built most rapidly before age five. A child who arrives at kindergarten having had rich early experiences starts on different footing than one who has not.
That is exactly why a 54 percent figure is worth a family's attention. It is not about pressure or flashcards. It is about making sure the youngest children get the interaction and stimulation that the science says matters most.
What families can do, starting today
The encouraging half of this report is that the most powerful early-learning interventions are not expensive programs — they are everyday moments, and any caregiver can offer them:
- Talk and narrate, constantly. Describe what you are doing, name things, ask questions. The number of words a young child hears is one of the strongest predictors of later language. Your running commentary at the grocery store is a literacy lesson.
- Read aloud every day. Even a few minutes. With babies it is about the rhythm and closeness; with toddlers it is vocabulary and attention. It is the single highest-return habit a family can build.
- Look into a program if you want one. If formal preschool is the right fit for your family, options exist — public pre-K, Head Start and Early Head Start for income-eligible families, and community programs like ours. Your local child care resource and referral agency can help you find a seat.
- Protect playtime. Unstructured, hands-on play is how young children build problem-solving, creativity, and self-regulation. It is not a break from learning; it is the learning.
The bottom line
The 2026 KIDS COUNT Data Book is a useful, uncomfortable mirror. It tells us that, as a country, we are not yet giving enough of our youngest children the early start they deserve. The fix is partly systemic — access, funding, quality — and we will keep pushing on that. But the part within reach of every family tonight is the oldest one in the book: talk to your child, read to your child, play with your child. The data is daunting. The response, at home, is beautifully simple.
