Forgotten NY profiles Kesington and kindly refers to our stretch of the woods as Brooklyn's Heartland.
Your webmaster must also admit that, prior to the 1980s or so, I never knew the area had a distinct name. I had always thought of it as an eastern extension of Borough Park or a northwestern arm of Flatbush. After a close look, though, Kensington has comparatively little in common with its neighbor to the west in demographics or in street layout; Borough Park, especially the area that borders Kensington, is mostly Hasidic and Orthodox Jewish, while Kensington, which certainly has a Jewish flavor, is incredibly polyglot with over fifty different foreign languages spoken. Perhaps it's that very diversity that prevented me from getting a fix on it.
