Moving out of your childhood home is often seen as a major step toward independence. It’s a mix of excitement, nerves, and new beginnings. But while many people pack up and start fresh, it turns out they’re not taking everything with them.

According to a new survey, most Americans continue to rely on their parents’ homes as long-term storage even after they’ve moved out.

Moving Out Doesn’t Mean Taking Everything

On average, people leave home for the first time around age 23, often feeling a mix of excitement (58%), nervousness (47%), and happiness (44%). But alongside those emotions comes a practical challenge: figuring out what to take and what to leave behind.

The survey found that Americans typically only take about 58% of their belongings when they move out. The rest? About 28% is left behind at their parents’ home, and another 14% is simply thrown away.

In total, that means roughly 42% of belongings don’t make the move, a reminder of just how much people accumulate before that first big transition.

Most People Still Have Things Sitting at Home

Even years after moving out, many people still have items sitting in their old rooms, closets, or storage spaces. In fact, 92% of respondents admitted they’ve left at least one belonging behind with their parents.

On average, that comes to about 9 boxes or large items per person. And for some, those items aren’t going anywhere anytime soon 27% said they have no plans to ever return to collect what they left behind.

Others say they’ll deal with it eventually, but not right away. While 30% plan to clear things out within the next year, 44% admit they’ve been putting it off without a clear timeline.

Why People Leave So Much Behind

There are a few reasons why so many belongings end up staying put. For some, it’s simply about space. About 31% said their new home didn’t have enough room, while others were limited by how much they could physically transport during the move.

But for many, the decision is more intentional. Some leave items behind for safekeeping (41%) or in case they might need them later (25%). Others hold onto the possibility of returning someday (25%), while some admit they’ve simply forgotten what they left behind altogether (23%).

In other words, those boxes in the garage or basement often represent a mix of practicality, uncertainty, and a little bit of procrastination.

Parents Are Still Holding Onto It All

From the parents’ perspective, the situation looks a little different but is just as common.

Among parents with adult children who have moved out, 38% said their kids still keep belongings at home. And while some have gently—or not so gently—encouraged their children to come pick them up (21%), most don’t seem to mind.

In fact, 58% said they’re okay with holding onto the items, often because they have the space. Some even prefer it that way, 30% said having their children’s belongings around gives them a reason to come back and visit.

There’s also a sentimental side to it. For many parents, those stored items aren’t just clutter; they’re reminders of a different stage of life.

The Stuff That Follows You—Even When You Move Again

Interestingly, the story doesn’t always end there. Half of the parents surveyed said they’ve moved homes themselves since their children moved out, and 83% brought those left-behind belongings with them.

That means some of these items are traveling from house to house, even if their original owners aren’t.

The Bottom Line

Moving out is often seen as a clean break, but for many Americans, it’s more of a gradual transition.

While people may leave home physically, a significant portion of their belongings stays behind sometimes for years. Whether it’s due to space, convenience, or sentiment, those boxes and stored items remain part of the story long after the move is over.

And for many families, that quiet arrangement where parents hold onto what didn’t make the cut has simply become part of the process.
