Final answer:
The majority of emerging adults in the United States and other Western countries do remain in their parents' home until marriage, which is true according to data from 2016 and the observed trends within many wealthy countries.
Step-by-step explanation:
In response to the question regarding whether in the United States and other Western countries, the majority of emerging adults remain in their parents' home until marriage, the accurate answer is A. True. As of 2016, a significant percentage of 18-to-29-year-olds in the US were living with their parents, the highest since 1900. This aligns with the broader trend in many wealthy countries, albeit with substantial variation. For instance, about 80 percent of 15-to-29-year-olds live with their parents in Italy, compared to 30 percent in Canada.
Changes in family structure and courtship mean that young women are increasingly leaving home for college before marriage, altering traditional patterns of adult independence. However, the majority still conform to living at home until later life stages. Additionally, there has been an evolution in the typical family setup, with increasing numbers of unmarried parents, same-sex couples, and multi-generational households.
With the rise of single parenting and cohabitation without marriage, societal attitudes towards marriage are changing. Many young adults are delaying or opting out of marriage altogether, contributing to the significant portion of young adults living with their parents until marriage or beyond.
