Unfortunately, Lemmy users are probably from all over the world and while there might be a handful of big cities that are relatively represented by a bunch of users, even that probably maxes out at like, say, 50 people from New York City or maybe L.A.
And that tiny sliver of citizens from each city is as big as you’ll find because those cities are over-represented in all things. If you live in bumfuck nowhwere? Rest assured, you’re probably the only person from your local area on Lemmy. I’ve seen numbers as low as 70,000 active users on Lemmy.
70,000, stretched all over the whole planet because there’s actually a lot of European Lemmy users as well as other countries, even though like usual, Americans are over-represented.
Like, that’s the population of the city I live in, and I don’t expect to run into any locals here. It’s just incredibly unlikely with so few active users.
