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.
