Population trajectory across census years
| Year | Population |
|---|---|
| 1881 | 537 |
| 1891 | 632 |
| 1901 | 675 |
Cross-year identity established by spatial polygon overlap (SAME_AS chains across the Canadian Census Subdivision boundary files).
Boundary continuity (non-identical overlaps)
Spatial polygon overlaps with adjacent census years where the boundary shifted enough that the SAME_AS chain didn't merge them. These show where the territory came from and went to even when it isn't tracked as the same persistent place.

- In a later year, this CSD contained Derry, 1911 (42.3% of this CSD's polygon).
- In a later year, this CSD contained Mulgrave, 1911 (57.7% of this CSD's polygon).
