Census source records

Each link states the assessment that connected the source row to this map. Name candidates remain candidates; no source statistic is silently assigned to the map.

Boundary intersections across censuses

These are computed polygon intersections in the equal-area CRS ESRI:102001. Fractions describe the area of the earlier and later polygons, respectively. They do not establish historical succession, and population has not been apportioned by area. All positive intersections are retained, including very small contributions.
