Chronic Disease Indicators
The chronic disease indicators (CDI) are a set of surveillance indicators developed by consensus among CDC, the Council of State and Territorial Epidemiologists (CSTE), and the National Association of Chronic Disease Directors (NACDD). CDI enables public health professionals and policymakers to retrieve uniformly defined state-level data for chronic diseases and risk factors that have a substantial impact on public health. These indicators are essential for surveillance, prioritization, and evaluation of public health interventions. More

National Survey of Children’s Health (NSCH) Data
Beginning with the 2016 survey year, the NSCH was redesigned. Because this redesign included changes in how the survey was administered and in what questions were asked, from 2016 on, NSCH estimates of dental visits and preventive dental visits for children and adolescents aged 1–17 years are not comparable to estimates from prior years.
