  • Canadian Community Health Survey

    The CCHS is a cross-sectional survey that collects information related to health status, health care utilization and health determinants for the Canadian population aged 12 and over. It surveys a large sample of respondents and is designed to provide reliable estimates at the health region level.

    Statistics Canada implemented a major redesign to the 2015/16 CCHS cycle and onward. Caution should be taken when comparing data from previous cycles to data released for the 2015 cycle onwards. As a result, this data portal only presents data from 2015/16 CCHS cycle and onward.

  • Early Development Instrument (EDI)

    The Early Development Instrument, or the EDI for short, is a questionnaire developed by Dr. Dan Offord and Dr. Magdalena Janus at the Offord Centre for Child Studies at McMaster University.

    The EDI is a 103-item questionnaire completed by kindergarten teachers in the second half of the school year that measures children’s ability to meet age-appropriate developmental expectations in five general domains including physical health and well-being, social competence, emotional maturity, language and cognitive development and communication skills and general knowledge

    The EDI is a reliable and valid measurement tool of developmental status completed on individual children between 3.5 and 6.5 years of age. After teachers complete the EDI on each individual child in their class, the results are grouped together to give a snap shot of how children are doing across schools, neighbourhoods, cities, or even provinces and countries.
