What does it mean to be an adult? Science, the law and even song lyrics have plenty of answers.

So do people of different ages, who have quite different views, according to a survey that asked respondents to choose what activities best defined adulthood.

Older people named financial responsibilities like investing, filing taxes, buying a house and having a budget.

Millennials have more fun. They were more likely to name hosting parties with friends, drinking wine and eating snacks for dinner if they wanted.

The youngest respondents, members of Generation Z ages 18 to 22, showed a more domestic side.

They were more likely than their elders to name buying a dishwasher, owning a pet and having a matching set of Tupperware.

The survey of 2,000 U.S. adults was commissioned by Food Rich to look at the role food plays in adulthood like snacking, grocery shopping and entertaining, the Georgia-based frozen food company said.

Boomers said their favorite age had been 30 to 32, millennials chose 20 to 23, and Gen Z went for their teenage years of 17 to 19.

“The findings in this study are both funny and true,” said Shannon Gilreath, Farm Rich director of marketing.

People of all ages said what they enjoyed most about being an adult was their independence.

Asked what they most disliked, older people named aging, stress and financial responsibilities.

Gen Z was more apt to add having to get up early, working and not having enough time.

Boomers said their favorite age had been 30 to 32, millennials chose 20 to 23, and Gen Z went for their teenage years of 17 to 19.

All ages generally agreed that the adult activities they liked best were being productive and checking things off their to-do list.

But far more Gen Z than boomers chose date nights with partners, eating snacks for dinner and hosting parties as their favorite adult activities.
