intended and unintended births in the united states: 1982 2010 /

This report shows trends since 1982 in whether a woman wanted to secure pregnant just before the pregnancy occurred. This is the most direct measure available of the extent to which women are able (or unable) to choose to fill the number of births they want,when they want them. In this report, this is called the ''standard measure of unintended pregnancy.''
