Some interesting articles I found from two different sites.

http://www.nytimes.com/2007/10/12/world/12 abortion.html?_r=1
http://www.foxnews.com/story/0,2933,301359 ,00.html

Both are pretty much the samething but studies done by different groups, basically legal and illegal abortions compare in numbers, although there is more deaths noted on illegal abortions.

Specifically 70, 000 woman dies worldwide from illegal(back alley) abortions this amount does not include the woman who have suffered minor, temporary of premanent damage to their health.

42 millions are performed each year ( back alley and legal)
26 Millions womam die every year
500 000 Woman die from child birth and pregnancy!
