It very much depends on your location.
That said, teens today are less into shopping at brick & mortar stores, hanging out at the mall, going on romantic dates beyond "netflix and chill", and going to places like movie theaters, parks, arcades, etc. compared to teens in the past. Even teens who do value going to these places today can Lyft and Uber their way there instead of owning a car which they'll have to pay a lot of money to keep.
Another factor that gets overlooked is how loitering laws have become stricter when it comes to teens. Sometimes, I'll take a break from work to grab a coffee at McDonald's and I'll see some teens just hanging out there and one teen will buy a light food item to justify them hanging out there.
Today's malls, retail stores, parks, and other public places do NOT play when it comes to teens just "hanging out" without justifying themselves. There's places that will literally kick teens out just for hanging or loitering around without buying shyt. The security in these places has stepped up their game especially in response to a minority of teens who've engaged in fighting and property damage who've ruined it for the rest of teens.
Teens have to justify themselves in many of the places they used to regularly hang out in without adult supervision these days. Social media, gaming, and videochatting are easier ways for teens to connect with each other without being heavily supervised.
