Although teen pregnancy is a well-recognized problem, the larger challenge of unplanned, unintended pregnancy among non-teens is poorly understood. Among teens the primary question is what to do? Among non-teens, the question is, what is the problem and why should I care? At present, fully half of all pregnancies are described by women themselves as unplanned. Among unmarried women in their twenties, seven in 10 pregnancies are unplanned. As is true for teen pregnancy, unplanned pregnancy—especially among single young adults—carries with it a broad array of socio-economic and health risks to women and men, to children, and to the larger community.
