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

2020 Behavioral Risk Factor Surveillance System (BRFSS) Data
The BRFSS 2020 colorectal cancer screening questions changed to include five test types (FIT, sigmoidoscopy, colonoscopy, FIT-DNA, and CT colonography) compared to three types (FIT, sigmoidoscopy, and colonoscopy) included previously. Estimates of people getting colorectal cancer screening are higher than in previous years. For more information, visit: Use of Colorectal Cancer Screening Tests | CDC.
Please consider differences in data collection [PDF – 168KB] and potential impacts of the COVID-19 pandemic when comparing 2020 BRFSS estimates with other years.
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.
