Slightly off topic but, i think, at some point, the most mobbed up city in Italy was the town of Filadelfia (Calabria) where it was estimated that about 10% of the overall population was inducted members of the N'drangheta locale. Considering the ratio between men and women + the children's population, it would mean that 2 out of 3 adult men living in the town were actual made members of the N'Drangheta.
