Devon Avenue is an East-West street on the north side, but it also refers to the part of Devon in West Rogers Park that is primarily a South Asian neighborhood along with a Russian/Jewish neighborhood.

While much of Devon was historically a Jewish neighborhood, the majority of the Jewish community (including the Russian Jewish community) is mostly now located west of California Ave. East of California, the neighborhood is primarily South Asian.
