Canada has a wealth of population-based administrative data on health, but with a dearth of information explicitly concerning race, ethnicity or SES. While area-based methods have been widely used with respect to neighborhood SES, such methods can also be used for routine surveillance of health data for areas with a relatively high proportion of aboriginal residents. Canadian postal codes are first converted to census dissemination area codes (US block groups), then health outcomes for dissemination areas with a high proportion of aboriginal residents are compared to otherwise similar dissemination areas with a low proportion of aboriginal residents. Because of its high concentration in isolated northern settlements, Canada's Inuit population is well identified using area-based methods. In rural and northern areas, First Nations communities are also fairly well-identified using such methods, but in urban areas they are much less highly concentrated, as are Métis people in both urban and rural areas.
