It’s not your imagination: Millennials really are glued to their smartphones.

Nearly four in 10 millennials (39%) say they interact more with their smartphones than they do with their significant others, parents, friends, children or co-workers, according to a survey of more than 1,000 people released Wednesday by Bank of America. That’s compared with fewer than one in three people of all ages who say they engage with their smartphones more.

This means that, on an average day, millennials — defined here as being ages 18 to 34 — “interact with their smartphone more than anything or anyone else,” the survey concluded.

This may not surprise anyone who has looked at millennial smartphone usage. More millennials (77%) own smartphones — and spend more time on them (over two hours a day) — than any other age group, according to a 2014 report that examined the behavior of more than 23,000 adults, and was released by Experian.“In fact, millennials spend so much time on their smartphones that they account for 41% of the total time that Americans spend using smartphones, despite making up just 29% of the population,” the report concluded.

Furthermore, nearly half of millennials — significantly more than any older age group — say they “couldn’t live without” their smartphone, according to data released in 2015 by the Pew Research Center, a nonprofit and nonpartisan think tank in Washington, D.C.

Millions of millennials couldn’t bear to part with their smartphones

Millennials are also far more likely to use their smartphone as a social escape: More than seven in 10 millennials say they have used their smartphone to avoid a social interaction, compared with fewer than half (44%) of others, according to the Bank of America data.

To be fair, millennials have many compelling reasons for using their smartphones: Experian data show that roughly one in five millennials (again, more than other age groups) use their phones to read the news during a typical week, and millennials are more likely than other cohort to use their phones to stay in touch with friends. What’s more, Pew data shows that millennials are more likely than other groups to use their phones to look at educational content, find and apply for jobs and learn more about a health condition.
