Why does it take so long to grow up today? | Jeffrey Jensen Arnett | TEDxPSU

Main ideas & concepts

• Growing up takes longer today than in the past

  • The speaker argues this is supported by measurable social trends over roughly the last 50 years.

• A “new life stage” has emerged: emerging adulthood

  • Positioned between adolescence and young adulthood.
  • A key shorthand claim: “30 is the new 20.”
  • In this model, many transitions that used to happen around age ~20 now happen closer to age ~30.

• Four major societal “revolutions” (starting in the 1960s–1970s) created the conditions for emerging adulthood

  1. Technology revolution

     • Society shifted from a manufacturing economy to a knowledge economy.
     • Manufacturing productivity increased, but it required fewer workers.
     • New, better-paying jobs increasingly require education beyond high school, delaying stable work.
     • Because stable employment often comes later, marriage and parenthood are also delayed.

  2. Sexual revolution

     • The birth control pill (1964) and other contraception methods broke the traditional link between sex and reproduction.
     • This also weakened the link between sex and marriage.
     • People begin sexual relationships in the late teens, while marriage typically comes much later.
     • Result: the late teens and 20s become a period for relationship change and exploration rather than immediate family formation.

  3. Women’s movement

     • Massive change in education and career access for women.
     • Example statistics:
       • 1960: far fewer women were in college compared with men.
       • Today: 58% of undergraduates are female; 42% male (and women are also prominent in professional schools like med/law/business).
     • This reshaped what young women expect to do with their 20s—more focus on education/career progress before settling into traditional life paths.
     • The speaker frames this as an overall positive expansion of opportunity.

  4. Youth movement

     • Adulthood lost some of its former status/authority, while youth became more idealized.
     • Cultural sayings like “I hope I die before I get old” and “Never trust anyone over 30” reflect this shift.
     • Young people increasingly prolong youth and delay entry into adult roles.

• Reframing criticism

  • The speaker notes many people see later adulthood timelines as evidence young people are “not doing it right.”
  • He challenges this view: later timelines reflect structural changes in the economy and social life, not personal failure.

• Why emerging adulthood can be beneficial

  • Better preparation for the knowledge economy.
  • More educational/career skill-building opportunities for both men and women.
  • Improved timing for relationships and parenting (the speaker suggests people may choose better partners later and be better parents at later ages).
  • Freedom is uniquely available:
    • Less immediate dependency on others (few responsibilities tied to family/long-term commitment yet).
    • People can try activities that may be harder later (travel, service projects, experimental career paths in the arts, etc.).
    • The freedom is temporary and should be used intentionally.

• Closing advice to emerging adults

  • Don’t let others pressure you into adulthood before you’re ready.
  • Adult life will eventually arrive, but entering it is hard to reverse—so use emerging adulthood well.

Implied “methodology” / guidance in instruction-like form

• For young people (emerging adults):

  • Don’t let “well-meaning people” push you into adulthood prematurely.
  • Remember: “It’s your life,” not someone else’s schedule.
  • Use the freedom of emerging adulthood strategically:
    • Explore other places/contexts (e.g., different regions or countries).
    • Consider service projects.
    • Try long-shot or creative career interests (e.g., arts).
  • Take advantage of the period when “nobody else really depends on you,” understanding this window narrows after commitments form.

• For people judging young adults’ progress:

  • Don’t assume later adulthood milestones mean something is wrong.
  • Interpret delays as responses to:
    • Requirements of the knowledge economy
    • Broader changes to gender roles/opportunities
    • Shifts in sexuality, marriage, and cultural expectations about age
