**Families are comprised of: 1) couples (married or common-law, including same-sex couples) living in the same dwelling with or without children, and 2) single parents (male or female) living with one or more children. Persons who are not matched to a family become persons not in census families. They may be living alone, with a family to whom they are related, with a family to whom they are unrelated or with other persons not in census families. Beginning in 2001, same-sex couples reporting as couples are counted as couple families. Characteristics such as age are as of December 31 of the reference year. A couple family consists of a couple living together (married or common-law, including same-sex couples) living at the same address with or without children. Beginning in 2001, same-sex couples reporting as couples are counted as couple families. A lone-parent family is a family with only one parent, male or female, and with at least one child.
