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.

**Source:** School attendance zones (this platform's school_attendance_zones topic, built from district and vendor sources); U.S. Census Bureau 2020 Census P.L. 94-171 block populations, TIGER/Line 2020 blocks and tracts, and TIGER/Line school district outlines.

## Query parameters

- `year` integer, nullable: Exact year
- `year_min` integer, nullable: Inclusive lower bound
- `year_max` integer, nullable: Inclusive upper bound
- `district_code` string, nullable: Comma-separated list of GOSA district codes (e.g. `601,602`)
- `school_code` string, nullable: Comma-separated list of GOSA school codes. Combine with `district_code` for unique school keys.
- `county_fips` string, nullable: Comma-separated list of 5-digit county FIPS codes (e.g. `13121,13067`)
- `tract_geoid` string, nullable: Comma-separated list of 11-digit census tract GEOIDs (e.g. `13121011100`)
- `block_group_geoid` string, nullable: Comma-separated list of 12-digit census block group GEOIDs (e.g. `131210111001`)
- `demographic` string, nullable: Comma-separated demographic codes (e.g. `all,black,hispanic`)
- `detail` string, nullable: Detail level (whatever the topic publishes — e.g. schools, districts, counties, or states).
- `limit` integer, nullable: Page size
- `offset` integer: Page offset
- `columns` string, nullable: Comma-separated output columns to return (fact columns plus joined dimension attributes). Defaults to all.
- `format` 'json' | 'csv' | 'parquet': Response format: json | csv | parquet

## Response `200`

Paginated rows. JSON returns an envelope with `data` and `pagination`; CSV/Parquet return raw bytes with `X-Total-Count` header.

- unknown

## Other responses

- `422`: Validation Error
