In Britain, only 8 percent of the population is Catholic (compared with 25 percent in the United States). Abortion there is legal. Abortion is free. And yet British women have fewer abortions than Americans do. I asked Cardinal Hume why that is.

The cardinal said that there were several reasons but that one important explanation was Britain’s universal health-care system. “If that frightened, unemployed 19-year-old knows that she and her child will have access to medical care whenever it’s needed,” Hume explained, “she’s more likely to carry the baby to term. Isn’t it obvious?”

A young woman I knew in Britain added another explanation. “If you’re [sexually] active,” she said, “the way to avoid abortion is to avoid pregnancy. Most of us do that with an IUD or a diaphragm. It means going to the doctor. But that’s easy here, because anybody can go to the doctor free.”
