About this ranking

Children aged 3 and 4 enrolled in public or private school, including nursery school and preschool, at any time in the three months before the interview, as a percentage of all children aged 3 and 4. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.

Reported by households, so it includes private nursery schools. Small counties have only a few dozen children in the sample, and their rates can swing widely between periods.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
