According to a new study by Pew Research Center, 21.6 million adults between the ages of 18 and 31 are living in their parent's homes.
Experts say there are a lot of factors that play into the amount of people living with mom and dad, like changing attitudes toward adulthood and an unstable economy.
19-year-old Surfside Beach resident Samantha Langley is one of these people. After leaving home once before, hearing that statistic wasn't a shock.
"It's not surprising that there's that many people home," Langley said.
Langley moved out of her parent's home for about a month, but had to move back since she couldn't afford to live on her own.
"It doesn't even matter how much you work, because I was working 40 hours a week and only getting $400 paychecks and it made no sense to me," Langley said.
Splitting that $400 every two weeks between bills and taking care of her 6-month-old son, Luke, she just can't afford to survive on her own.
"You're trying to do your best, and it's like you're not getting anywhere," Langley said.
Even going back to work within the next few months will set her back financially.
"I have to go back to work soon, and it's like just thinking about having to go buy pants, it's like having to buy two pairs of pants will put you in the hole," Langley said.
Since 2007, the number of millennials living at home has risen by 3.1 million.
