This website contains definitions (but not data) for over 120 public health indicators. Public health epidemiologists in Ontario collaborated with various partners to collate extensive information on each indicator. The result is a resource that enhances accurate and standardized reporting of information across public health units in Ontario.
The Core Indicators were originally created to link to objectives outlined in the Ontario Ministry of Health and Long-Term Care’s Mandatory Health Programs and Services Guidelines. They are now being revised to reflect the Ontario Public Health Standards released in November 2008. The Core Indicators form the foundation for community health status reporting in public health in Ontario.

It is our goal to keep the information on this web site as current and relevant as possible. Please contact the webmaster if you notice any outdated information, incorrect information or inactive links.



"I just wanted to say (Though you've heard a million times) - how great the revisions of the indicators are - we have been using them a lot & they have helped point out some fixes that need to be made to our RRFSS data dictionary pages."
APHEO member, July 2009 

"I was on the site yesterday and am very impressed. People who worked on these did a tremendous job. This is a wonderful resource, particularly the table at the bottom that reflected the changes and the link to the standards makes it easier for us to apply the data."

"What an incredible project you and your colleagues continue to develop. The APHEO indicators site is a veritable gold mine of information, guide and HELP for those of us who are particularly scientifically challenged. My thanks to you and all your colleagues for this most useful web-site!"
District Health Council Planner, November 2004

"I must say congratulations on an informative and useful web site for the population health indicators. I have just started searching for others that are working in the area of performance measures for public health and I received wonderful information at this site!"
