Target group profiles (TGP) provide Census Profile variables for a subset, or target group, of the population. This TGP provides the Census Profile for the population with income below the after-tax Low Income Measure (LIM-AT) threshold.
'Low-income measure, after-tax (LIM-AT)' refers to a fixed percentage (50%) of median adjusted after-tax income of private households. The household after-tax income is adjusted by an equivalence scale to take economies of scale into account. This adjustment for different household sizes reflects the fact that a household's needs increase, but at a decreasing rate, as the number of members increases.
Target group profiles (TGPs) provide data for a specific group of persons (a "target group"). All variables in the Target Group Profile are ‘person-level’ variables: their age, their gender, their family status (e.g., are they in a census family), the languages they speak, and so on. Because TGPs deal with the universe of persons, they do not contain any family- or household-specific variables. For example, the average family size, household income or renter/owner status are variables that do not relate to a person, but to a family or household, and so they are not included in TGPs.
25% vs 100% samples – Comparing values with publicly accessible data
The 2021 short form Census questionnaire was sent out to 100% of all households. The 2021 long form Census questionnaire was sent out to 25% of all households. Target Group Profiles are produced using the 25% sample. Variables that are available in both the 25% sample and the 100% sample will have different values depending on the source of the data. For example, the total population of a city taken from the 25% sample (a Target Group Profile) will differ from that taken from the 100% sample (the online Census Profile).
