BJJ Demographics

Last week I provided some general demographic data about who exactly completed the 2012 BJJ belt promotion survey. This week I’m starting to get into the real meat of the data by focusing on some of the specific ‘Brazilian Jiu Jitsu’ demographics. The results/trends reported are all based on averages (corrected for outliers), but even with that it’s important to bear the general demographics (see the previous week’s post) of the sample in mind, before drawing any broader conclusions.

Still, despite the typical survey limitations there are some nice trends which are likely to apply to their wider BJJ population (such as the time spent training by various belts, the proportion of roles for each belt, etc.). There are also some things that surprised me from the data, specifically:

1) The relatively high average age of people training in BJJ: I had kind of expected averages, at least for white and blue belts, to be in the low twenties, maybe teenagers and people in the early 20s aren’t taking online surveys?

2) Committed white belts: 6 hours would translate to roughly 3 x 2 hr classes a week or 4 x 1.5 hr classes. 3/4 sessions a week is certainly normal for lots of white belts but the average? It seems a bit higher than my personal experience suggests!

3) 6 hours being the mean/median average amount of hours trained: Again I had expected there would be more beginners training once a week that would pull down the average but while there are plenty of people who meet that profile they are offset by a large group training more frequently (typically 3-5 times a week). On a side note, the highest hours training a week reported was 40 and the lowest predictably was 0.

There’s plenty more data to come and I haven’t even touched the topic of gradings/belt promotions yet! So feel free to drop me a line if there is any specific data you are curious about. I’m also happy to share more detailed results with anyone interested in the statistical nitty gritty. Next week I’ll dig into some of the psychological data relating to motivations and personality types.
