How does census geography fit with health geography in BC, and in Canada?
Census geographies and health regions do not nest hierarchically. In BC, best fit linkages can be created between dissemination areas or census subdivisions and local health areas (LHA)s or health service delivery areas. Whether the fit is close enough depends on your research project. Generally, rural areas with low populations are problematic. In urban areas, dissemination areas, census subdivisions, and LHAs generally nest relatively cleanly.
