The NY State Education Department just released its official public school enrollment numbers. In the 2021-22 school year - the third school year impacted by COVID - town of Greenburgh public school enrollment continued its decline since 2018-19, but the pace of decrease slowed, and some districts had small increases over last year. Yet the three year overall decline (2.8% or 437 K-12 students) townwide now suggests a trend, rather than a statistical irregularity. When NYSED releases the nonpublic and home school enrollment stats later this spring, we'll get a better sense whether students have left the public school system, or families with school-age children are decreasing in the town, consistent with historically low national fertility rates.
Note the above enrollments are for K-12 only. Greenburgh Central, Elmsford and Tarrytown include preK in their publicly announced enrollments numbers, but to compare the ten Town of Greenburgh school districts, I've excluded preK. Also, note that as the enrollment numbers are collected and reported by the school districts in October and November of each school year, 2019-2020 enrollment total precede the impact of COVID starting in March 2020.
