A while back I asked myself: How many people actually dance the Tango? You won’t find an answer to this question. I couldn’t find any numbers, not even good guesses.
Part of the problem is, that there is no worldwide Tango association, backed by national associations like you would have in sports. Sure, there is the “official” Tango world championship. But its claim for being official comes from being organized by the city of Buenos Aires. This form of the organization won’t be able to help to find out how many people are actually dancing recreationally.
How could we get at least an idea regarding this question? A representative worldwide study is a bit beyond the resources of 030tango (but I would love to see this happening!) and being a huge fan of the XKCD
„What if?“ blog, I decided to treat it like a Fermi-Problem. True nerd style.
I don’t really care if there are 1.45 million or 1.78 million Tango dancers in the world. What I do care about, is if there are 1 million or 10 million Tango dancers in the world (or just 100,000… or maybe you are the only one?).
A general sense of curiosity is the main motivation to work on this. But yes, it’s also important for me to see, in what dimensions 030tango could grow, just by exclusively reaching the Tango community. 030tango takes up a lot of time and resources. If I want to be able to continue the project long-term, there has to be an audience for it and I have to know how big this audience is.
