Fewer young adults in the U.S. are reaching traditional adulthood milestones such as marriage, parenthood, full-time work, and living independently, according to new U.S. Census Bureau data. Nearly half of 25- to 34-year-olds met those benchmarks 50 years ago, compared with less than a quarter today, according to CNBC. Analysts say rising student debt, housing costs, and inflation are pushing milestones later, despite more young adults earning college degrees. The median age of first-time homeowners has climbed to a record 38 from the late 20s in the 1980s, National Association of Realtors data shows. Financial advisors note that many now delay marriage and children until achieving financial stability.
