Prognosis

Advances in medical care have made it possible for many premature infants to survive and develop normally. However, whether or not a premature infant will survive is still intimately tied to his or her gestational age:


* 21 weeks or less: 0% survival rate

* 22 weeks: 0-10% survival rate

* 23 weeks: 10-35% survival rate

* 24 weeks: 40-70% survival rate

* 25 weeks: 50-80% survival rate

* 26 weeks: 80-90% survival rate

* 27 weeks: greater than 90% survival rate


Physicians cannot predict long-term complications of prematurity and some consequences may not become evident until the child is school--aged. Minor disabilities like learning problems, poor coordination, or short attention span may be the result of premature birth, but can be overcome with early intervention. The risks of serious long term complications depend on many factors including how premature the infant was at birth, weight at birth, and the presence or absence of breathing problems. The development of infection or the presence of a birth defect can also effect long term prognosis. Severe disabilities like brain damage, blindness, and chronic lung problems are possible and may require ongoing care.

It looks like 23-25 weeks has had a lot of increases in survival rate, yet have a very broad range for chances of survival which suggests to me that this age is probably where a lot of the serious complications occur.

Facts about Induced Abortion
This site cites its sources well and appears to be relatively unbiased to me. They appear to be a legitimate site. It is dated Jan. 2011.

When women have abortions (In weeks from the last menstrual period)
Eighty-eight percent of abortions occur in the first 12 weeks of pregnancy, 2006.

So when we talk about late term abortions, we're talking about less than 2% of all abortions.

WHO HAS ABORTIONS?

Eighteen percent of U.S. women obtaining abortions are teenagers; those aged 15-17 obtain 6% of all abortions, teens aged 18-19 obtain 11%, and teens under age 15 obtain 0.4%. [6]

Women in their twenties account for more than half of all abortions; women aged 20–24 obtain 33% of all abortions, and women aged 25-29 obtain 24%. [6]

Thirty percent of abortions occur to non-Hispanic black women, 36% to non-Hispanic white women, 25% to Hispanic women and 9% to women of other races. [6]

Thirty-seven percent of women obtaining abortions identify as Protestant and 28% as Catholic.[6]

Women who have never married and are not cohabiting account for 45% of all abortions.[6]

About 61% of abortions are obtained by women who have one or more children.[6]

Forty-two percent of women obtaining abortions have incomes below 100% of the federal poverty level ($10,830 for a single woman with no children).

Twenty-seven percent of women obtaining abortions have incomes between 100-199% of the federal poverty level.* [6]

The reasons women give for having an abortion underscore their understanding of the responsibilities of parenthood and family life. Three-fourths of women cite concern for or responsibility to other individuals; three-fourths say they cannot afford a child; three-fourths say that having a baby would interfere with work, school or the ability to care for dependents; and half say they do not want to be a single parent or are having problems with their husband or partner.[7]

So, in short, poorer women, women in their twenties, and women who have had at least one child represent the majority of women who have an abortion. The statistics about race are a bit confusing since there are likely more white women than there are black or hispanic women the numbers there are not proportional.

The risk of death associated with abortion increases with the length of pregnancy, from one death for every one million abortions at or before eight weeks to one per 29,000 at 16–20 weeks—and one per 11,000 at 21 or more weeks.[13]

Fifty-eight percent of abortion patients say they would have liked to have had their abortion earlier. Nearly 60% of women who experienced a delay in obtaining an abortion cite the time it took to make arrangements and raise money.[14]

Teens are more likely than older women to delay having an abortion until after 15 weeks of pregnancy, when the medical risks associated with abortion are significantly higher.[14]

So, it is riskier to have a later term abortion, and even more so for a 'late-term' abortion. But money and the amount of time it takes to get an abortion are the primary reasons people had a "delay" in getting an abortion. That's across the board remember, not just for late-term abortions as that is only 2% of all abortions.
