Do a lot of Italians live in PA, especially in Philly and Pittsburg, and do a lot live in Chicago, IL?

South Philadelphia used to be predominantly Italian. But many have moved over to Gloucester County, NJ. Even the Italian Market area has a lot of Mexican and Asian shops now. Pittsburgh has a small Italian neighborhood, Bloomfield. A few old industrial towns upstate have Italian neighborhoods because in the early 20th century, factory owners would literally wait at the dock for boats coming in from Italy and gove newly arrived Italian immigrants jobs as soon as they cleared Ellis Island. And I'm sure Chicago has a high Italian population too, as its known for its pizza.

Well i'm obviously not Italian but I do know if you go to South Philly that area is predominantly Italian. I know this because my mother used to work in that area.

Philadelphia still has many people of Italian descent. A good number are concentrated in "deep South Philadelphia". But, like other immigrant groups as people became more successful they moved to South Jersey, Montgomery and Delaware Counties. Pittsburgh's Bloomfield neighborhood still has a decent sized Italian community. As with Phila, people moved to the suburbs. Towns like Aliquippa (north of Pittsburgh) and Monessen (south of Pittsburgh) had large numbers of Italians who worked in the mills. Since the great migration from Italy to the US occurred from the late 1880's until about 1920, there are at least three generations since people were picked up on arrival and sent to the mills and mines for work.
