"Indeed, most young people today no longer go on 'dates' to get to know a potential partner. Instead, they meet each other at a social event, 'hook up', and then go on dates (if the hookup went well).4"

Can you provide more back up on the "most" here? I tried to find more information, and while I could only locate reviews of the Bogle book online, none of them even mentioned any numbers. However they did make it sound like Bogle did not get a representative sample of "young people today." If there is not sufficient empirical back up to say " most," you might instead say "many" or "a growing portion."
