Couple family - a family based on two persons who are in a registered or de facto marriage and who are usually resident in the same household.

Family - two or more persons, one of whom is at least 15 years of age, who are related by blood, marriage (registered or de facto), adoption, step or fostering; and who are usually resident in the same household.
