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.

Individual records from the 1881 census
The individual census transcription is a separate dataset. Existing person citation anchors and the published geographic grouping are preserved. These records are not population totals derived from the rebuilt aggregate tables.
