According to Fred Barnes’ article:
“Three pro-life trends have spiked in 2011. The first is the rise in opposition to abortion among young people. The under-30 cohort was the most pro-choice in the 1970s, second most in the 1980s and 1990s. Now they’re “markedly less pro-choice” than any other age group, scholars Clyde Wilcox and Patrick Carr have written. “Clearly, something is distinctive about the abortion attitudes of the Millennial Generation of Americans. Indeed there is. Millennials haven’t grown more religious, politically conservative, or queasy about gay rights. Nor do they go out of their way to vote for pro-life candidates. But they tend to see abortion as a human rights violation. Thus their resistance to abortion is gradually increasing…”
This is an important and hopeful trend. See more helpful analysis at the STR blog, here.
