The data for this variable are reported using the following classification(s) and/or list(s):

'Adjusted after-tax income' refers to after-tax income adjusted by a factor that accounts for family size. The adjustment factor takes into account the lower relative needs of additional family members, as compared to a single person living alone.

Note: In the context of economic families, adjusted after-tax income is computed as the economic family after-tax income divided by the square root of family size.

In the context of persons not in economic families, adjusted after-tax income is equal to after-tax income. This is equivalent to dividing by the square root of 1.0 for a person not in an economic family.

'Economic family' refers to a group of two or more persons who live in the same dwelling and are related to each other by blood, marriage, common-law or adoption. A couple may be of opposite or same sex. Foster children are included.

By definition, all persons who are members of a census family are also members of an economic family. Examples of the broader concept of economic family include the following: two co-resident census families who are related to one another are considered one economic family; co-resident siblings who are not members of a census family are considered as one economic family; and, nieces or nephews living with aunts or uncles are considered one economic family.
