Final answer:
The main reason for young adults returning home to live with their parents is the lack of job opportunities post-graduation, due in part to an economic stall affecting the Boomerang Generation. This, coupled with societal changes and the high cost of living, leads many to seek the financial and emotional support of living with parents.
Step-by-step explanation:
The main reason for young adults returning home to live with their parents is often the lack of job opportunities. Economic challenges faced by the Boomerang Generation, a term coined to describe recent college graduates, often compel them to move back in with their parents after failing to find adequate employment post-graduation. This trend is highly influenced by an economic stall that has led many Millennials to postpone traditional adult responsibilities and roles. Today, obtaining a bachelor's or even a graduate degree is becoming increasingly necessary even for entry-level jobs, further exacerbating the issue.
Moreover, some societal shifts have contributed to this phenomenon, such as longer life expectancies in wealthier, more industrialized nations allowing more time to establish a career and family. The shift has resulted in many young adults taking extra time to explore their options, change majors, and job hunt, thereby delaying marriage and career start times compared to previous generations. These factors also contribute to the high cost of living, which can make it difficult for young adult graduates to afford their own place, often leading to the necessity of parental support.
