Global family planning stakeholders convened on July 11, 2012 for the London Summit on Family Planning Summit to mobilize commitments to support access to family planning information, services, and supplies by an additional 120 million women and girls in the world's poorest countries. The Measurement, Learning & Evaluation (MLE) Project seeks to remind world leaders that half of the world's population now live in urban areas and almost all global population growth will occur in towns and cities in developing countries over the coming decades. A commitment to securing access to family planning products and services in poor urban areas is a critical component to this summit's success.
