Acknowledgments.

This report builds on over a decade of research by The Alan Guttmacher Institute (AGI) and many others. It represents two years of direct research, analysis and thought by AGI staff members Patricia Donovan, senior associate for law and public policy; Jacqueline Darroch Forrest, vice president for research; Jennifer Frost, senior research associate; David J.
