Gen Z and Baby Boomers are slightly more likely to say they have lots of indoor plants, while Millennials are the most likely to say they don’t own any. Men and women report nearly identical levels of indoor plant ownership. Those earning over $100K annually are the most likely to say they have lots of houseplants, as are city residents and those living in the Northeast and West.

But demographics aren’t the only thing separating plant owners from non-owners. CivicScience data reveal several lifestyle and personality differences between those with many houseplants and those with none:

• Phone cleaning: Those with lots of indoor plants are more than 10 points more likely to say they regularly clean the outside of their phone or phone case (46% vs. 35%).
• Learning for fun: Those with lots of houseplants are more than twice as likely to say they’ve taken several educational classes purely for fun outside of school or college (31% vs. 14%).
• Movie theater habits: They’re also nearly three times as likely to say they often bring outside food into a movie theater (23% vs. 8%).
• Dining outdoors: Plant owners are far more likely to prefer eating dinner outdoors, while those without houseplants tend to prefer dining indoors.
• Open-face sandwiches: Houseplant enthusiasts are twice as likely to say they’re fans of open-face sandwiches (31% vs. 15%).
