I think FB has scooped up the older half of millennials. FB was the hot thing as they were just getting to college, when it was still limited to college kids. We can't discount outside of US/Europe though — they're big over there too. As for Snap, they definitely have Gen Z or whatever it's called, but I don't think the data on Snap is as strong. And Instagram has a strong hold on them too. Most teenagers I know keep Snap/Insta, and if they had to pick between the two, it'd be Insta.
