The table illustrates the changes in household composition in a North American country between 1970 and 2003, showing the percentage of different types of family and non-family households.
Overall, the most notable trend is a significant decline in the proportion of married couple households, accompanied by an increase in other household types.
When it comes to family households, married couples represented the largest category in both years, though their share dropped considerably, falling from 61% in 1970 to 41% in 2003. Father-and-child households experienced a minor increase, rising by 1 percentage point from 9% to 10%. Mother-and-child households also grew slightly, accounting for 10% in 1970 and climbing to 11% in 2003. Meanwhile, households with other members sharing edged up from 13% to 14%.
In terms of non-family households, there was a striking surge in single-person households, which expanded more than threefold between the two years, starting at 4% and reaching 13%. Similarly, room-sharing households saw a significant rise, advancing from 3% in 1970 to 11% by 2003.
