How often do Dwellers appear in Fallout Shelter?
Dwellers show up randomly in Fallout Shelter, but the Radio Room can help attract them more frequently. Also, pregnant Dwellers increase your population, but that takes some time. There isn't a set schedule, so keep your eye out and your vault door open!

Honestly, it feels super random. Sometimes you get a bunch quickly if you use the Radio Room, or when you're just starting. But other times, it's like a wasteland out there with no one new showing up for days.
I've noticed more Dwellers come after big achievements or when expanding my vault. Keep your vault growing and they will come!
