High school attainment: definition and scope
Residents age 25 and older with at least a high school diploma or equivalent. The headline is the latest value approved within this website’s frozen release. It is not a promise that no newer upstream product exists. The accessible table retains more precision than the rounded headline.
Limitations and comparability
Includes equivalency credentials. Adult attainment differs from student enrollment and cohort completion.
The estimate describes the full 2020–2024 ACS period. Compare it with the same five-year product and universe. One-year ACS, model-based products and administrative counts cannot be joined into an unlabeled series.
Source count margins of error are retained in the raw download, but a margin of error for this calculated percentage is not supplied. We do not infer significance from point estimates, claim statistically settled ranks, or silently convert missing cells to zero. Cross-area associations do not establish individual circumstances or explain what caused a difference.
Source data, calculation and CSV downloads
Use the original selected cells, schema and formula with the immutable release. Summary-file columns use E001/M001; formulas use the corresponding ACS codes ending in E. Percentage numerators and denominators are supplied in the export.
