Mobility
Mobility refers to the movement of individuals on a geographic basis, whether it’s international migration between B.C. and the rest of the world or inter-provincial migration between B.C. and other Canadian jurisdictions. The term mobility encompasses those statistics that show the number of migrants, where they’re going to and where they’re coming from.
