According to confidential documents from overseas - which the AGI has been able to view - the Genovese family can now count on 175 members, that of the Gambinos on 165, the Bonanno on 132, the Lucchese on 121 and the Colombo on 90. Hundreds of other affiliated people must be added to these numbers. Each member, in fact, has the possibility to affiliate between 5 and 10 people.
In all, therefore, there are between 3400 and 6800 affiliated to "La Cosa Nostra" only in the state of New York.

There are not only the "five families" in the USA.

In Buffalo there is the Todaro family, whose head is Joseph Todaro Jr. and the sub-chief is Domenico Violi. According to what was learned by the AGI, the "family" controls the business of Niagara Falls and Hamilton in Ontario.

In Philadelphia there is the Merlino family, with at least thirty members and constantly growing. Here, the recent release of the boss Joseph Merlino is increasing the mafia caliber of the family in the so-called "Tri State Area" (New York, New Jersey and Connecticut) and has a strong relationship with the Genovese.

Another important area for the Cosa Nostra is that in Elizabeth, the county seat of Union County in New Jersey. Here we find the “strong family” of the De Cavalcante, with a hundred affiliates and an important contiguity with the Gambinos.

In Boston is the Patriarca family that controls drugs, gambling, usury and illegal labor racketeering.

In Los Angeles we find some members of the Gambino family.

Finally, Miami: here the situation is very varied, a sort of "open city" with all the aforementioned families present and a "new entry", the Caruana-Cuntrera, historic mafia family from Agrigento (known as the Rothschilds of the mafia or the bankers di Cosa Nostra) which has tentacles in the Miami economy, in absolute connection with the other "families".

The Camorra does not have an autonomous structure in the US, but has historical ties with the Genovese family, some Italian affiliates have properties in Florida (particularly nightclubs).
