A survey suggests many people in Britain make major life changes during their thirties, including moving abroad, changing careers, starting businesses, and launching side hustles. The reporting ties different milestones to specific ages: moving abroad is reported at about 31, career changes at about 32, and starting a business at about 33.

The same survey also points to a later peak for starting a side hustle, reported at about 34. Across the outlets provided, the emphasis stays on timing rather than the reasons behind these decisions. Both accounts present the findings as survey-based averages and do not attribute the data to additional causes such as economic conditions, demographics, or regional differences. No other contrasting interpretation, methodology detail, or differing numbers are included in the sources supplied.

Overall, the coverage aligns on the central takeaway: early-to-mid 30s appear to be a common period for significant personal and professional shifts.
