Don't think the Mexican cartels are the biggest OC groups in terms of membership. Asian criminal organizations tend to have a ton of members. The Yamaguchi-gumi for instance, even at its all time low, has a whopping 9.500 members.
yes, in terms of membership yamaguchi-gumi is probably the biggest worldwide, i don't know how many associates but the full-time members/made members are currently 10.000 and in the past they reached 50.000
