Notes

1. Polls show that about a quarter of the population is "pro-life," and another quarter is "pro-choice." The fifty percent in the middle hold compromise positions, and sometimes inconsistent and contradictory views. (See

Most people simply do not want to think about abortion, so they don't.

2. After reaching a high of over 1.6 million in 1990, the numbers of abortions performed annually in the U.S. have dropped to around 1.06 million a year (http://www.nrlc.org/uploads/factsheets/FS01AbortionintheUS.pdf).
