GAW, New York is by far the biggest with mekomos Torah and Chesed as well as Gedolim and Rabbonim. You can hardly walk a block in Flatbush, Boro Park, Williamsburg, Crown Heights, etc. without at least one Bais Medrash, Yeshiva, Beis Hakenesses, shteeble, Chesed organization, etc. Lakewood is next.
In-Town refers to New York City. All of Brooklyn is a vadai. The other boroughs its possible for someone to argue against, but its a shvach case.
