Population in Anchorage Mat-Su Economic Region

About this data

The official state population numbers from Alaska's state demographer: statewide, 6 economic regions, and all 30 boroughs/census areas, annually (July 1 reference). Alaska ~738.7k and roughly flat; the internal story — Mat-Su growing, Anchorage shrinking, rural areas mixed — is the interesting part, and this dataset is the dashboard's "sort population by region" backbone.

Known issues & gotchas

• Verified layout (2026-08-06, Vintage 2025): single sheet, 43 rows × 15 cols. Rows 1–3 = title/header padding; row 4 = column labels (Area Name, April 2020 census, July 2021…July 2025 estimates, then components-of-change columns); rows 5–41 = data; last 2 rows = vintage + source footnotes.
• Hierarchy by indentation: region rows unindented (Gulf Coast Region), borough rows indented three spaces. Strip and classify by indent.
• Name forms differ from the LAUS CSV: Anchorage, Municipality of vs LAUS's Municipality of Anchorage; Skagway Borough, Municipality of vs Municipality of Skagway; regions drop "Economic" (Gulf Coast Region). The connector normalizes to the canonical LAUS-aligned slugs — geography must join across datasets.
• Whole file is one vintage: each new vintage restates all estimate years. Load with vintage awareness; the April 2020 census column is fixed.
• The file only covers 2020+ — deep history (1960+) lives in other files on the pop index page; add a backfill file if the dashboard wants the long arc (worth it: statehood-era growth chart).
