No source, naturally.
As Murdock acknowledges, the number of abortions was declining nationwide during this period -- obviously for demographic reasons -- and New York City merely reflected that trend.

You're resorting to trolling mentality - demand a source, provide your own, but only partially quote it so as to make it fit your opinion. I can quote the same editorial you do and have it say exactly the opposite. Your so-called quote wasn't in context - and neglected this statement, also from your article: "But he points out that during Giuliani's tenure as mayor, the number of abortions fell in New York City by more than the national average, and Giuliani did not actively promote policies that would have led to an increase in the number of abortions."
