I want to echo ATF's thanks, Neko.  It's always good to have statistics.  
As many have stated repeatedly, the best way to reduce the number of abortions is to make birth control more available.  The insistence of the Catholic Church that contraception is wrong is driving up the number of abortions.  So, we can say that the hierarchy is directly complicit in abortions -- it is causing an increase by its obstinate stand on contraception.
