For decades, the cultural blueprint was quite straightforward: graduate from school, secure a steady job, get married, purchase a house, and have kids. Checking these boxes meant you had officially arrived in adulthood.
Over the past half-century, however, society has been rewriting this playbook.
At least 95% of Americans still agree that finishing an education and achieving financial independence are the defining markers of adulthood. But a US Census Bureau report revealed that more than half now view marriage and parenthood as largely optional.
This shifting landscape has given rise to what experts call “emerging adulthood” — a distinct developmental phase spanning from 18 to 29.
Coined by Dr. Jeffrey Jensen Arnett, a professor of psychology at Clark University, the term captures a prolonged period of exploration and uncertainty.
“This demographic space has opened up where people are less dependent on their parents but have not yet entered the settled roles of adult life, making the 20s different than they were before,” says Dr. Arnett.
While pop culture often glams up your twenties as the absolute peak of your life, the ground reality is quite different. Most people have to deal with sky-high rents, a savage job market, and systemic economic instability.
All these factors are forcing millions to delay major life milestones.
A study found that in 2005, only 11% of young adults in the US aged 24 to 35 lived with a parent. By 2023, that figure climbed to 18% as the rising cost of living altered household structures.
Financial independence has also become harder to achieve. In 1980, 42% of 21-year-olds could support themselves financially. By 2021, that number had fallen to just 25%.
It turns out that one of the hardest parts of adulthood is rarely a big or dramatic catastrophe. Instead, it’s daily tasks like paying bills, scheduling and keeping appointments, healthcare, cooking, and household chores.
A 2026 survey of 2,000 Americans found that 69% felt overwhelmed by household responsibilities. Nearly two-thirds said they found the need to clean before they could relax stressful.
Respondents reported spending an average of six hours every week cleaning and recovering from household chores alone.
The same survey found that many adults felt reality fell short of expectations —around 70% said adult life was less enjoyable than they had imagined.
Experts believe that the human brain has a limited amount of processing power, and it becomes overwhelmed when it has to make hundreds of minor choices every single day.
A study found that the average American adult makes 35,000 decisions every single day. Choosing what to wear or what to cook for dinner might seem minor, but experts note that our brains process information much like a physical muscle.
After a day full of decisions, the brain gets tired. And that’s when some people start procrastinating or making snap decisions.
That’s also why deciding what to stream on Netflix might somehow feel impossible after a day spent answering emails and dealing with household responsibilities.
Struggling with adulthood is not a personal failure, though.
Rising living costs, economic uncertainty, artificial intelligence overload, political instability, and the lingering effects of the pandemic all make life stressful.
The challenge is to learn how to manage the stress, instead of finding shortcuts to completely eliminate it.
“Emerging adults struggle with difficult identity questions, which can make this a lonely time of life. They may not necessarily be happy during this decade, but there’s a widespread sense that no matter how hard life is now, it will get better,” says Jeffrey Jensen Arnett, PhD, a professor of psychology at Clark University in Massachusetts.
