1 Beginning in 1994, preprimary enrollment data were collected using new procedures. Data may not be comparable to figures for earlier years.

2 Beginning in 2010, standard errors were computed using replicate weights, which produced more precise values than the generalized variance function methodology used in prior years.

3 Enrollment data for 5-year-olds include only those students in preprimary programs and do not include those enrolled in primary programs.

NOTE: Preprimary programs include kindergarten and preschool (or nursery school) programs. “Preschool,” which was referred to as “nursery school” in previous versions of this table, is defined as a group or class that is organized to provide educational experiences for children during the year or years preceding kindergarten. Data are based on sample surveys of the civilian noninstitutionalized population, which excludes persons in the military and persons living in institutions (e.g., prisons or nursing facilities). Detail may not sum to totals because of rounding.
