Adults are currently facing challenges in reaching these 4 key ‘milestones.’ Are you one of them?

Changing Milestones of Adulthood

Life was certainly different back in 1975. People commonly believed the American Dream was attainable, and achieving adulthood mapped out with just a few milestones seemed quite feasible.

A recent working paper from the US Census Bureau suggests that today’s young adults aren’t hitting the same milestones their parents or grandparents did half a century ago.

The paper delves into census data and looks at four key milestones for those in their 20s and early 30s: moving out of their parents’ home, securing a job, getting married, and starting a family.

In 1975, nearly half of Americans aged 25 to 34 checked off all four milestones. Fast forward to today, and it’s under 25% for the same age group.

Interestingly, around 22% of young adults today have moved out, married, and even started families—similar to their 1975 counterparts.

However, trends have shifted over the years. Researchers note that the combination of living independently, being married, and having children is much rarer now. In fact, the most common adult experience among young adults in 2025 still emphasizes employment. According to census figures, 28% of those aged 25 to 34 are working while living independently.

The next largest group, about 21%, has managed to fulfill all four primary criteria. This figure is less than half of what it was 50 years ago.

When comparing milestone combinations over five decades, the percentage of young adults who are married, living independently, and working has remained quite stable. Back in 1975, about 15% met these criteria independently, while today, it’s around 14%. Interestingly, participation in the workforce has increased, from 3% in 1975 to the current rate, but living apart with children has dropped from 22% to just 8% now.

The working paper highlights several factors that could influence today’s pathways to adulthood. Economic pressures and the need for financial security may push priorities into different areas. A recent study indicated families of four with incomes below $200,000 can comfortably live in just seven states. Additionally, with a mere 10% down payment, a limited number of metropolitan areas fit within budget constraints. Over 30% of American households struggle to earn enough to be categorized as middle class, and there’s an observable decline in the belief that parenthood is essential to adulthood.

The paper states, “Economic circumstances can impact decisions regarding marriage and parenthood, which in turn affect labor market participation.”

Another significant element is education. Programs requiring over four years of study, particularly at universities, have gained popularity. This educational commitment can inevitably delay reaching those four key adult markers.

Researchers have pointed out that “milestones of adulthood are often interrelated,” introducing complexities that previous generations may not have dealt with.

Ultimately, what defines adulthood today includes a variety of elements: reduced birth rates, soaring housing costs, a challenging job market, and evolving economic priorities.
