Transnational Metropolitan Areas

[Hatman 🍁]

The US Census bureau uses counties/county equivalents when they define metro areas, whereas Statistics Canada uses municipalities. Canadian municipal boundaries make more sense than US municipal borders, while most provinces don't have counties (there are equivalent 'census divisions', but they don't usually make for nice metro areas when lumped together). The result is comparing Canadian and US metro areas is like comparing apples and oranges. Under the US definition, a Detroit-Windsor MSA would include all of Essex County, whereas in reality the Windsor CMA (Census Metropolitan Area) only includes 5 of Essex's 9 municipalities.
