Census source records

No source row has a supported or candidate endpoint here in the current assessment. This does not mean the population was zero.

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.
