What is the IPD?

The Incidence & Prevalence Database (IPD) is the most efficient way to look at the world’s epidemiology data. The IPD covers over 4,500 diseases, procedures, symptoms and other health issues for incidence, prevalence, morbidity, mortality, comorbidity, treated or diagnosed rates, cost and much more.

Some of the main features of the Incidence & Prevalence Database include:

Efficient & Accurate

TDR’s research team is comprised of senior analysts with over 10 years' experience with epidemiological data and training in evidence-based medicine. Our analysts appraise the text, tables, figures, and references of hundreds of full-text medical journals, government audits, and other industry sources on an ongoing basis. This full-text appraisal ensures that every source in the IPD is timely and relevant.

After a source has been accepted into production, our analysts write a customized IPD Article Review that includes epidemiological data, methodology details, and other useful content. In addition, top-line IPD Summary reports are compiled from Article Reviews to provide a comprehensive look at selected diseases or procedures in a single report. All data contained in the IPD is fully cited and is linked to the Article Review and from there to the original full-text of the document.


Our analysts track and report the epidemiological content for hundreds of medical journals and dozens of government and industry agencies. For a complete list of our resources, see the IPD source information page. The global reach of the IPD includes all countries and regions where data is available. For more information about the IPD, including a full description of the database's features, read the FAQ.
