text: Furthermore, emerging adulthood occurs only within societies that allow for occupational shifts, with emerging adults often experiencing frequent job changes before settling on a particular job by the age of 30. Arnett also argues that emerging adulthood happens in cultures that allow for a period of time between adolescence and marriage, the marker of adulthood. Such marital and occupational instability found among emerging adults can be attributed to the strong sense of individualization found in cultures that allow for this stage of development; in individualized cultures, traditional familial and institutional constraints have become less pronounced than in previous times or in non-industrialized or developing cultures, allowing for more personal freedom in life decisions. However, emerging adulthood even occurs in industrialized nations that do not value individualization, as is the case in some Asian countries discussed below.
  Up until the latter portion of the 20th century in OECD countries, and contemporarily in developing countries around the world, young people made the transition from adolescence to young adulthood around or by the age of 22, when they settled into long-lasting, obligation-filled familial and occupational roles. Therefore, in societies where this trend still prevails, emerging adulthood does not exist as a widespread stage of development.
