Context: These datasets include the following census geographic units: enumeration areas (EA), census tracts (CT), and census subdivisions (CSD). EA geography contains population and dwelling unit counts. CT geography contains population, household, dwelling count and a number of housing variables. The CSD geography does not contain population or dwelling data but can be linked to lower and upper level geography.
Process: Tabular information has been added to each data set so that one geographic unit can be linked to another by name and numeric ID. For example, with these data a user can identify all dissemination areas that reside in a lower or upper-tier municipality (CSD or CD) simply with the name of the relevant municipality. Furthermore a variable attached to that lower level of geography can be summed for a higher level of geography. This is particularly useful for calculating a ratio where the denominator may be an entire lower or upper-tier municipality.
