"In my orbit" there 100% of the people play racquetball which means there are roughly 350 million players in the USA - hence it is the most popular sport on the planet and owner of my local team is richer than all NFL owners combined /s :)
Also see https://www.statista.com/statistics/408971/number-of-us-face... just for kicks :)
ok well at least that's the number that was being discussed.
maybe i sound like i'm wearing a tin hat but i don't totally trust their active user numbers or believe that facebook is growing active users in the US. like am i in there bc i have a facebook acct from years ago to run ads and accidentally clicked a fb link once last year? what if i viewed a facebook ad. at some point somebody is deciding what counts as active and i'd bet a dollar that person is incentivized for numbers to be big and monotonic.
in my experience it's good to poke at numbers that don't match your intuition. that's how you get to reality.
i know your example was farcical, but if you know a lot of people and 100% of them play racquetball, you should seriously question someone who is telling you that football is actually the most popular sport, especially if they have economic incentives for you thinking that's the truth. it's just math.
