Data from the 2011 census released today portrays changes in the makeup of Canadian families and living arrangements over the past 50 years.

   It's no surprise that it reveals Canadian households are now a complex system of family ties involving living alone, re-marriage, stepchildren, empty-nesters and multiple generations sharing a home.

   Married couples are in a long-term decline, single parenting continues to rise and for the first time, Statistics Canada says there are more people living alone than there are couples with children.
