Americans are closely divided between those calling themselves “pro-choice” and those who are “pro-life,” now 49% and 45%, respectively, in Gallup’s 2011 update on U.S. abortion attitudes. This is similar to a year ago, when 45% were “pro-choice” and 47% “pro-life.” However, it is the first time since 2008 that the “pro-choice” position has had the numerical advantage on this Gallup trend…

Since 1994, Gallup has also asked those who think abortion should be legal under certain circumstances to say whether it should be legal in “most” or “only a few” circumstances. On this basis, Americans are rather conservative in their stance on abortion, with 61% now preferring that abortion be legal in only a few circumstances or no circumstances. By contrast, 37% want abortion legal in all or most circumstances.
