Ciao, Frank! Your English is a lot better than my Italian.

There are still some significantly Italian neighborhoods in the five boroughs of New York, like Bensonhurst and the others mentioned. But the important thing is that those neighborhoods are not almost exclusively Italian, as they were only a generation ago. What's happened is that Southern Italians used to be very insular in their neighborhoods, always suspicious of outsiders. In that environment, Mafia activity could flourish and be kept quiet. Now Italian Americans are fully assimilated. College, not the Mob, is the career of choice for smart young Italian Americans. The Mafia gets the John and Junior Gotti's, and the Gaspipe Casso's.
