A crosswalk between Georgia public school attendance zones (the school_attendance_zones geometry topic: the area whose residents a school serves for a run of grades) and 2020 census tracts. One row per school, grade and tract its zone covers at that grade. Population weights are 2020 Census P.L. 94-171 block populations: each 2020 block counts toward the zone holding its interior point; a block that a zone line crosses (two or more schools' zones, or a zone and an unzoned gap, each covering over 1% of it) is split by area, in whole persons; a block whose interior point lies just outside today's district line goes to the zone covering most of it; any other block outside every zone is a gap. Use pct_of_tract_population to answer 'which zones cover this tract at this grade, and how much of it', and pct_of_zone_population to roll tract data (the census topics) up to a zone. year is the school year the zones are in effect for (2027 = 2026-27); the population is the 2020 census. Zones are not official enrollment determinations; each zone's source, method, vintage and accuracy are on the zones topic.

Filterable categorical columns (comma-separated values union; multiple columns AND together):

• zone_level — one of: elementary, high, middle
• grade_level — one of: 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, k
• is_largest_zone_for_tract (free categorical)

Detail levels available: schools (default: schools)

Year coverage: 2027–2027 (1 years, no gaps)

NULL handling: zero is a real value.
