(November 2017) Since the early 1960s, many countries have instituted large-scale programs to provide contraceptive protection to their populations. Since that time, hundreds of national surveys have been conducted and statistics have been collected from clinics and health centers at local levels. The rich data sets that have appeared over the years permit insights into the dynamics of how large-scale family planning programs do and do not work well.

This report by John Ross, an eminent demographer, includes selected topics that portray various relationships among contraceptive elements and among certain demographic outcomes. This publication is useful for those who seek a deeper understanding of the dynamics that surround contraceptive use. The format for each topic states first the key relationship, then discusses it briefly, usually with references for further reading, and with an accompanying figure that illustrates the dynamics involved.
