The Tracking Program provides information communities can use to improve their health. This information comes from a nationwide network that integrates health data and environmental data. CDC's Tracking Program has laid the foundation of this national system by providing grants to state and local health departments.

CDC funds health departments in 23 states and 1 city to build and implement local tracking networks. These state and local data systems feed into the national Tracking Network. Previous projects by these grantees have improved information technology through better infrastructure, expanded environmental public health tracking capacity, and trained public health workers. Most importantly, grantees have developed better ways to make information accessible on the Tracking Network to those who need it to take action, such as policy makers and public health officials.
