The table illustrates the percentage of family and non-family households in a North American nation between 1970 and 2003.
Overall, most of the listed categories witnessed an upward trend, with the exception of married couples. Additionally, married couples remained the largest share of the total household composition throughout the surveyed period.
Looking closely at family households, in 1970, it can be seen that married couples accounted for the majority (61%) of all households. In 2003, despite a significant plummet by 20%, they still maintained their leading position in the proportion of household composition. By contrast, single-father families recorded an 1% increase in the 13-years timeline, reaching 10% in the end of the period. Single-mom and unidentified households experienced similar growth, beginning at 9% and 10% before rising to 10% and 11%, respectively.
Regarding non-family households, the proportion of people living independently tripled from 4% in 1970 to 13% in 2003. Similarly, the share of room sharing households started at a modest beginning (3%), before surging to 11% in 2003.
