 The Upper West Side is a traditional landing zone for immigrant populations.Often associated with Sicilian immigrants who came to Buffalo in great numbers starting around the turn of the twentieth century, today the area has large Somali, Sudanese, Middle Eastern, Eastern European, Mexican and Central American, Puerto Rican, and Southeast Asian enclaves.While the district has experienced significant disinvestment and blight, it is experiencing revitalization, reflecting the area's new demographic and interest from "urban pioneers" and recent immigrants.
