Science is a public good and knowledge is a source of power.

The Society of Family Planning compiles summaries of research — what the science says — on key topics to serve as a resource to members and advocates and to contribute to the goal of ensuring that the evidence base informs advocacy and decision-making. Often, but not always, Society members have conducted the research. We update these documents as new research is published.
