Students enrolled in each grade each fall, stacked to the total — so the top edge is total enrollment. Bands run from the lowest grade (light) to the highest (dark); a band that appears or disappears is a grade the school added or dropped. “Other” is students with no grade level (mostly special education), so the bands always sum to total.

How much the mix changed

Between 2014-15 and 2018-19 the makeup of this school shifted noticeably.

That’s the ninth-largest shift among the district’s 13 elementary schools — smaller than 70% of Mercer County elementary schools. That roughly tracks the district overall (9.6) — a district-wide change more than a school-specific one. The biggest moves, in percentage points:
Black −5.8·Hispanic +4.9·Two or more +0.7

Not reported by the state in some years (shaded). Since 2014, some districts provide free meals to all students regardless of household income, which can lift the eligible share.
