The Limitations of U.S. Statistics on Abortion

And a snippet from the article on why women have abortions:

What Are the Reasons Women Have an Abortion?
In 1987 and 1995, AGI collected information nationally on the socioeconomic characteristics of approximately 10,000 women obtaining abortions. The results of the 1995 survey show that the women who are most likely to obtain an abortion have an annual inco me of less than $15,000, are enrolled in Medicaid, are aged 18-24, are nonwhite or Hispanic, are separated or never-married, live with a partner outside marriage and have no religious affiliation. Catholics are as likely as the general population of women to terminate a pregnancy, Protestants are less likely to do so, and Evangelical Christians are the least likely to do so.
The only comprehensive source of information on the reasons women give for their abortion decision is from a 1987 AGI survey of 1,900 abortion patients nationwide. The survey deliberately oversampled women having abortions beyond 15 weeks of gestation, although the number was still relatively small (420).
The vast majority of respondents cited a variety of socioeconomic and family considerations as their main reasons for seeking an abortion. Most of the women reported that more than one factor contributed to their decision, with the average number of reaso ns being four. However, 3% of respondents said that the "most important reason" for their decision was concern for their own health, and another 3% cited concern that the fetus had a health problem.
The women having abortions after 15 weeks attributed their lateness in obtaining the procedure to not having realized earlier that they were pregnant (or how long they had been pregnant), having had difficulty in arranging the abortion and (in the case of teenagers) having been afraid to tell their parents they were pregnant.

are nonwhite or Hispanic, are separated or never-married, live with a partner outside marriage and have no religious affiliation.

Yeah, that's what I said. Unmarried women. Many of which would easily qualify for slut I'm sure.

Here's a telling bit though...

• Three out of four pregnancies among married women (75%) ended in a live birth in 2004, while 19% ended in fetal loss, and 6% ended in abortion.
• For unmarried women, slightly over half of pregnancies (51%) ended in live birth, an increase from 43% in 1990. 35% of these pregnancies ended in abortion and 13% ended in fetal loss.

I wonder how many of that 6% was due to adultery?

Unfortunately, there are all too many men like you out there, and none of them have a big tatooed sign on their foreheads to warn women. Until men take responsibility for controlling their sexuality, they have no business condeming women for sexual mistakes.

Or maybe women become sluts because so many men are scumbags. If you want to make abortion rare, force scumbags to get a tattooed forehead.

Are you going to be the first in line?

Since women have more to lose, it's up to them. They bear the brunt of pregnancy disease and social stigma. You wanna be a slut, fine, but that's just what people will think of you. Cept of course for other sluts, who will blame the men.
Or women could just make sure the man loves her for her and aren't just looking for a living penis pouch.

No need for now. 12 almost 13 years monogamy with my wife. But if something happened that made me single, I would need one. Cause the great thing about being older that I've found...is older sluts. Desperate Housewives is a lot more than the title to a show.

Too bad for women they created stuff like viagra. Now the ugly old coots still expect sex from their wives all the time. Yuck.

Or perhaps men just shouldn't be such weak and helpless little things.

You remind me of my father who had a moderate drinking problem until the medical community declared alcoholism a 'disease'. Then he declared that he had an 'illness', not a problem, that it wasn't his fault, and within a month had developed a severe drinking problem.

Blaming others for your weakness is cowardly.

Screw that, they are divorcing their wives and expecting sex from younger fresher women. Somebody grab the Grecian formula and the soloflex. I need a new piece o booty. Men are visual, the old wife just won't do any more.
