Through Countdown to 2015, FCI works with scientists, governments, UN agencies, nongovernmental organizations, and fellow advocates to publish robust, objective data and analysis of the state of reproductive, maternal, newborn and child health (RMNCH) in the 75 highest-burden countries. With this data in hand, advocates can track how women and children are faring in their countries and push for interventions that are proven to work. Countdown’s recently published Country Case Study Briefs on Malawi, Ethiopia, and Tanzania, created by FCI with our Countdown partners, use data to explain those countries’ successes and highlight their remaining challenges in improving women’s and children’s health. These briefs also offer important lessons for other countries facing similar health challenges.
