Not every statistic is collected every year — each row shows its most recent available school year (amber when older than 2024–25). Blank/absent means not collected or below reliability floors, never zero. Some universal-meals states no longer report free/reduced-price lunch — school poverty (MEPS) is the better lens there. A 0% charter share in a state without a charter-school law is a true zero.
