The number of made men in families, and their "power" vis-a-vis others, is guesswork at best. The FBI and local law enforcement base their estimates on informants and the seats of their pants, not on anything concrete, much less "published."
For a criminal organization that doesn't intentionally release press reports, it doesn't come much better than informants who are able to identify made guys. And the FBI, as a matter of practice, requires the independent verification of two members before they consider a particular guy to be made. Over time, the feds have been able to build up quite an index of past and current members. Even Capeci said that their figures have been considered very accurate, and consistent, since the early 1980's. But the further you go back beyond that, the more questionable the estimates become.
