According to Gallup 48% of Americans describe themselves as "pro-choice," compared to 44% who describe themselves as "pro-life." Yet only last year
Gallup reported a record low number of self-described pro-choicers (41%, compared to 50% "pro-life"). That's a lot of fluctuation, and (again according to Gallup's trends) the labels have been fluctuating for several years now.
Depending on which way the percentages move, one side of the other will emphasize the poll and talk about long-term, big-picture changes in the never-ending national abortion debate. Maybe they're right, but I don't think we can really see that from these polls.
Labels like "pro-life" and "pro-choice" are not as well-defined as abortion activists like to suggest. I suspect people's reasons for choosing one label or another have to do with a lot of factors beyond their perspective on abortion specifically. For example,
some pollsters suggest recent changes may be due to ignorant Republican comments about
rape and pregnancy, or due to last year's contraception debates. I also suspect adherence to pro-choice and pro-life labels have a lot to do with how people feel about the Democrat and Republican parties at a given time, even if their feelings about the parties change due to topics other than abortion.
And of course there's a lot of ambiguity about what the terms "pro-choice" and "pro-life" imply. To my mind, a pro-choice person is someone who believes, at minimum, that women should be able to get abortions for any reason during the first trimester, and for severe reasons (rape, life/health of the mother, fatal fetal abnormalities) in the second two trimesters. A "pro-life" person is someone who believes, at minimum, that abortion should be illegal throughout all stages of the pregnancy except for those severe reasons. There are more "pure" pro-choicers and pro-lifers who may argue that the above definitions compromise too much, but my point here is not ideological purity. I'm trying to summarize what I think the majority of people in the abortion debate would consider "pro-choice" or "pro-life."
Yet I've met people who think that they are technically pro-choice because they believe in exceptions for rape and life of the mother. And I've met plenty of "personally pro-life" people who think abortion is a necessary evil that should be legal. How do people like these respond to polls?
Meanwhile, as
Secular Pro-Life has pointed out, a recent
Pew Research Poll found only 62% of adults knew Roe v. Wade was about affirming a woman's right to an abortion. In fact, 17% of adults thought the case had to do with school desegregation, the death penalty, or environmental problems. I don't really blame them--if you're not passionate about abortion I can understand not knowing anything about Roe v. Wade. I'd be hard-pressed to name a landmark SCOTUS decision about the environment.
Still, I wonder how much national ignorance plays a roll when
Gallup asks people whether they thought Roe v. Wade should be overturned (53% said no, 29% said yes, and 18% said they don't care).
It's also interesting how the "pro-choice" and "pro-life" demographics break down:
Religion.
Having no religion is
the biggest predictor for being pro-choice--bigger, even, than being liberal. Note, though, that the intense correlation doesn't cut both ways: 80% of the nonreligious are pro-choice, yet only 50% of non-Catholic Christians and 45% of Catholics are pro-life. In fact, more Catholics called themselves pro-choice than pro-life! And yet we're allegedly a Catholic movement?
Politics.
73% of liberals and 63% of Democrats call themselves pro-choice. 63% of conservatives and 67% of republicans call themselves pro-life. I never have been that clear on the distinctions between liberal/Democrat and conservative/Republican. They seem to generally follow the same polling trends. In any case this still leaves roughly 1/3 of Democrats who don't consider themselves "pro-choice" and 1/3 of Republicans who don't consider themselves "pro-life." If the labels weren't so strongly associated with specific political parties, how might that change peoples' self-descriptions?
Education.
The more college education a person has, the more likely they are to say they're pro-choice. Other polls have shown the more college education a person has, the
less religious that person tends to be. And it's no surprise that education is positively correlated
with income. In other words, while it's clear that education and the "pro-choice" label are correlated, it's not clear whether (a) increased education causes people to be pro-choice, (b) being pro-choice makes it easier for people to increase their education (how many women cite
disruption to their education as a reason to get an abortion?), or (c) being pro-choice and being well-educated are both correlated with some third causal factor, like being non-religious.
Income.
I think this factor surprised me the most.
According to Guttmacher, 73% of women who get abortions cite financial problems as a major reason. Yet the less income a person has, the less likely they are to say they're "pro-choice." I'm not sure what to make of that.
I would love to see a poll that asks more about the legality of abortion, and less about labels. It should also ask not just whether abortion is moral or immoral, but
why respondents think it's moral or immoral. Maybe that would shed more light on the national perception of the abortion debate.
