Can some longtime New Yorkers (and particularly Harlemites) help me out with this one? I've been in Harlem for about six years, and New York almost ten. I know that the boundaries of neighborhoods tend to fluctuate. Still, thinking more on the geography the Times calls "Harlem" raises some questions for me:

But the neighborhood is in the midst of a profound and accelerating shift. In greater Harlem, which runs river to river, and from East 96th Street and West 106th Street to West 155th Street, blacks are no longer a majority of the population -- a shift that actually occurred a decade ago, but was largely overlooked.

By my estimate this basically places Morningside Heights (amongst other things) inside of Harlem. I imagine that might have been true at some point. But those borders sound really permissive to me. Am I off?
