Average family size by family structure

The average family size among all Census families—with or without children—has declined over the last generation. In 1971, the average family in Canada had 3.7 people; by 2006, that number had dropped to 3.0. Similar decreases have been observed among husband–wife families (from 3.8 to 3.0) and among lone-parent families (3.1 to 2.5).
