Which also means that the number people where >1k people know them also increases. The question is about proportions and locality. I feel pretty confident in saying that the rate of non-local celebrities has dramatically increased faster than population. I would also wager that the number of total celebrities (as defined above) has also increased faster than population and accelerated through the instagram and even more through the tiktok age. We have far more ways to communicate than previously, especially non-local. I can talk to someone in Japan without a HAM radio nor an expensive long distance phone call. Hell, I wouldn't be surprised if someone living in Japan reads this comment.

You cant actually be confident until you run a statistical test
