These numbers are for the entire city, not just Manhattan. The bad old days of the late 70s-early 90s are over, just accept it. It's weird how hard some people fight good news.
Btw, the 'mourning old New York' thing pisses me off as well, as things have moved on and it's a welcome change that crime is down in Manhattan. I'm observing, not judging, when I say that the the city is playground for the rich.
