This document discusses communicating population health data for impact. It notes that population health data from the Global Burden of Disease study can help answer questions about major health problems, diseases causing high mortality, diseases affecting older populations, prioritizing diseases for vaccine research, and the health burden of obesity. The data includes mortality and disability metrics for 301 diseases across 188 countries from 1990 to 2013. The goal is to share this data with global health organizations, governments, researchers, private sector groups, healthcare providers, investors, journalists, and the general public to help inform decision making. It emphasizes tailoring the sharing of data to the right audiences, formats, and timing.
