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.
