Student enrollment has declined in three out of four Long Island school districts over the past decade, as much as 25% in some, as schools grapple with families having fewer children, an aging population and people leaving who can't afford to live here, according to state figures and a Newsday analysis.

Of Long Island's 124 school districts, 94, or 76%, saw their student population drop from the 2012-13 school year to the 2022-23 school year, with some districts seeing substantial decreases, including Kings Park (-29%), Port Jefferson (-26%), West Hempstead (-23%), Smithtown (-22%) and Commack (-21%), according to the most recent figures from the state Department of Education.

In total, the Island's student population dropped by 33,394, or 7.35%, in the decade, from 455,384 to 421,990, the figures show.
