Overview

Postsecondary enrollment outcomes (GOSA C11 report) for Georgia public high school graduating cohorts: the number of high school graduates and the number of those graduates who enrolled in any postsecondary institution (in-state or out-of-state, 2-year or 4-year, tracked roughly one year after graduation), by demographic subgroup, for every Georgia public high school plus official district and state rollups. Covers HS graduating cohorts 2010-2022 (published 2012-2024). No rates are published — consumers derive the enrollment rate as num_enrolled_in_college / num_graduates.

Row grain: One row per year, district_code, school_code, demographic.

Key metric

num_enrolled_in_college — Number Enrolled in College (count)

Variables

Every column in the fact table. The code is the exact field name the API returns.

Column	Type	Unit	Range	Null?	Description
`year`Year	integer	—	—	no	High school graduating-cohort year (spring calendar year of graduation, e.g. 2022 for the class of 2021-22) — NOT the publication year, which is consistently cohort + 2. Read from the source's School Year / SCHOOL_YEAR column and cross-checked against the filename offset.

Read from the source's School Year / SCHOOL_YEAR column and cross-checked against the filename offset.
`district_code`District Code	string	—	—	yes	GOSA district code (FK to districts dimension): 3-digit zero-padded county/city codes or 7-digit state-charter codes. NULL on state-level rows. Full description▾ GOSA district code (FK to districts dimension): 3-digit zero-padded county/city codes or 7-digit state-charter codes. NULL on state-level rows. Joins districts; adds its label columns.
`school_code`School Code	string	—	—	yes	GOSA school code, zero-padded to 4 characters (composite FK to schools dimension with district_code; not globally unique on its own). NULL on district- and state-level rows. Full description▾ GOSA school code, zero-padded to 4 characters (composite FK to schools dimension with district_code; not globally unique on its own). NULL on district- and state-level rows. Joins schools; adds its label columns.
`demographic`Demographic	string	—	—	no	Student subgroup the row covers (race, gender, economic, or special-population); 'all' is the cohort total. Race uses the split asian / pacific_islander convention. Full description▾ Demographic subgroup (FK to the global demographics dimension). Race buckets use the post-1997 OMB SPLIT convention — asian and pacific_islander are separate, mutually exclusive groups (the seven race buckets sum to the 'all' total at the state level within a residue of at most 8 graduates in every year from 2011). The 2010 cohort (published 2012) has no pacific_islander rows — the source did not publish the group that year — and its six race buckets undercount the total by ~1.1% (race-reporting transition year). 'all' is the unfiltered total and overlaps every other value; subgroups are mutually exclusive only within their own category (race, gender, economic, special population). 14 allowed values▾ `all` `asian` `black` `economically_disadvantaged` `english_learners` `female` `hispanic` `male` `migrant` `multiracial` `native_american` `pacific_islander` `students_with_disabilities` `white` Joins demographics; adds its label columns.
`num_graduates`Number Graduates	integer	count	—	yes	Number of students in the demographic subgroup who graduated high school in the cohort year. Published values are always >= 10 because GOSA suppresses smaller cells per metric (TFS); ~51-53% of metric cells are suppressed in every file, concentrated in small subgroups (Migrant, Pacific Islander, American Indian/Alaskan Native, LEP) at school level. If num_graduates is suppressed, num_enrolled_in_college is always suppressed too (enrolled <= graduates).

`num_enrolled_in_college`Number Enrolled in College	integer	count	—	yes	Count of the cohort's graduates who enrolled in any US college within about a year; divide by num_graduates for the college-going rate. Full description▾ Of the subgroup's high school graduates, the number who enrolled in any postsecondary institution (in-state or out-of-state, 2-year or 4-year), tracked roughly one year after graduation. Never exceeds num_graduates where both are published (enforced by a quality check). Named to match the postsecondary_c12 sibling for cross-topic comparability. Published values are always >= 10 (GOSA's per-cell suppression threshold).

Notes & limitations

NULL handling

Suppressed cells (too few students to report) are NULL, never zero.
Zero is a real, reported value.

Limitations

Suppressed cells are NULL (not zero): GOSA suppresses any metric cell below the n=10 reporting threshold (TFS), which blanks ~51-53% of metric cells in every file — small subgroups (Migrant, Pacific Islander, American Indian/Alaskan Native, LEP) are almost entirely suppressed at school level, and summing only published subgroup counts undercounts true totals (use district or state rows for official aggregates). Suppression is per metric cell, so num_enrolled_in_college can be NULL while num_graduates is published. year is the HS graduating-cohort year, not the publication year (cohort + 2). The 2010 cohort has no pacific_islander rows and its race buckets undercount the total by ~1.1%. State rows have NULL district_code and school_code; district rows have NULL school_code. The race axis uses the split asian / pacific_islander convention — not comparable row-for-row with combined-convention topics without aggregating these rows at query time.
