A recent study published in the journal Developmental Psychology on May 15, 2026, indicates that the age at which young people consider themselves adults has shifted to approximately 27 years old. Researchers from the University of Cambridge surveyed 2,000 individuals aged 18 to 35 across the United Kingdom, finding that financial independence, stable employment, and moving out of the parental home were key markers of adulthood.
The study, led by Dr. Emily Carter, found that only 23% of respondents aged 18-25 felt they had reached adulthood, compared to 78% of those aged 30-35. Economic factors, including rising housing costs and student debt, were cited as primary reasons for the delay. The average age of first-time homebuyers in the UK is now 34, according to data from the Office for National Statistics.
Dr. Carter noted, 'The traditional milestones of adulthood—marriage, homeownership, parenthood—are being postponed or redefined. Young people today prioritize emotional maturity and self-sufficiency over external markers.' The study also highlighted that 65% of participants considered 'taking responsibility for one's actions' as the most important indicator of adulthood.
