I just wanted to give everyone a glimpse of how dense some divisions are in comparison to others. These counts are for fighters above the starter rating and have had a pro fight in the last 450 days that we know about. The recorded count is what we currently have in the database, while the estimated count factors in data availability to give a more “true” count. Nevertheless, journeymen with records like 1-7 are likely not going to be included.
Using this info, it’s fair to say that the average fighter weighs in at about 169 pounds — and probably walks around at about 195 :).
It should be interesting to see how this changes with the UFC bringing in Flyweights and also after they have the Featherweight and Bantamweight divisions for another year or two.
