Chronic Disease Indicators (CDI)

The Chronic Disease Indicators (CDI) is a cross-cutting set of 98 indicators that were developed by consensus and that allows states, territories and large metropolitan areas to uniformly define, collect, and report chronic disease data that are—

  • Important to public health practice
  • Available for states, territories and large metropolitan areas

In addition to providing access to indicator data, the CDI Web site serves as a gateway to additional information and data resources.


CDI are divided into eight categories that represent a wide spectrum of conditions and risk factors as well as social context:

  • Physical activity and nutrition
  • Tobacco and alcohol use
  • Cancer
  • Cardiovascular disease
  • Diabetes
  • Arthritis
  • Overarching conditions
  • Other diseases and risk factors


The Council of State and Territorial Epidemiologists (CSTE) originally worked with epidemiologists and chronic disease program directors at the state and federal level to select, prioritize, and define 73 chronic disease indicators. The first set of indicators was published in 1999, with state-specific data published the following year. In 2001 the content of both reports became available online. In 2002, CSTE adopted a revised and expanded set of indicators—Council of State and Territorial Epidemiologists Position Statement: Revise Chronic Disease Indicators (CDI)—to reflect expert and stakeholder recommendations.*PDF Icon (PDF–111KB)

This site presents the most up-to-date CDI definitions. The Chronic Disease Indicators are a collaborative effort of the following organizations:


For each indicator

  • Consistent methods for conducting analyses were established to provide data that can be compared across geographic areas.
  • Surveillance data are available for the majority of states and large metropolitan areas.
  • A comprehensive definition was established, comprising the following elements:
    • Demographic group
    • Numerator
    • Denominator
    • Measures of frequency
    • Time period for case definition
    • Background
    • Significance
    • Limitations of indicator
    • Data resources
    • Limitations of data resources
    • Healthy People 2010 objectives


  • Indicators are related to diseases/conditions with substantial public health burden.
  • Indicators are consistent with Healthy People 2010 measures where possible.
