Population of each Georgia public school's attendance zone, all ages and ages 5-17: estimated residents (the key metric) and residents per square mile of land, each with a 90 percent margin of error, and the zone's land area, from the American Community Survey 2020-2024 5-year estimates (table B01001, sex by age). A zone that is its whole school district carries the Census's own figures for that district, and one that is its whole county the county's (estimate_source). Every other zone is built from block-group estimates placed in the zone by the school_attendance_zone_block_groups crosswalk's 2020 population shares. Land area is the zone's 2020 census land, built the same way for every zone. Two rows per school and zone level, one per age_bracket. year is the school year the zones are in effect for (2027 = 2026-27).

**Filterable categorical columns** (comma-separated values union; multiple columns AND together):
- `zone_level` — one of: `elementary`, `middle`, `high`
- `age_bracket` — one of: `all`, `5_17`
- `estimate_source` — one of: `school_district`, `county`, `block_groups`
- `zone_differs_by_grade` (free categorical)

**Detail levels available:** schools (default: `schools`)

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

**NULL handling:** suppressed cells are NULL (not zero); zero is a real value.

**Source:** U.S. Census Bureau, American Community Survey table B01001 (sex by age) for school districts, counties and block groups (the 2020-2024 five-year release) and 2020 census land areas; school attendance zones and their 2020 census block group crosswalk (this platform's school_attendance_zones and school_attendance_zone_block_groups topics, weighted by 2020 Census P.L. 94-171 population).
