Final answer:
The question relates to trends in Canadian household compositions according to the 2011 census, but most resources provided are about U.S. trends, where an increase in nontraditional households has been reported. The subject is Social Studies, and the level is high school.
Step-by-step explanation:
The question implies a discussion on trends in household composition based on census data, which falls under Social Studies, reflecting sociological aspects of demographics. Canadian census data from 2011 indeed showed interesting trends in household types, with shifts from traditional to more nontraditional households. However, most of the provided references and resources focus on United States census data and trends. For the Canadian context, specific references to the 2011 census would need to be consulted to answer the question accurately, which might show similar or different trends compared to the U.S.
According to the U.S. Census Bureau and sources such as the National Journal, there is evidence to support the statement that there has been a rise in nontraditional households in the United States, indicating greater diversity in family structures. This information illuminates the changes in modern families, reflecting variations in family life, the market revolution's impact on social and economic structures, and sociopolitical trends such as voting rates.
