In-depth EDI by category


This map shows EDI results by category: experiencing great difficulty in one or more areas of development (EGD1+), experiencing great difficulty in two or more (EGD2+) and developing appropriately in all five (DA5). Results are shown for communities and subcommunities. EDI summary results are also provided, along with the percentage of children experiencing great difficulty in each of the five areas of development in the categories EGD1+ and EGD2+. Pie charts report results for each area of development. The five areas are: physical health and well-being, social competence, emotional maturity, language and thinking skills, and communication skills and general knowledge. An overview is also provided for the areas of development in which children are doing the best and in which they are struggling the most. For more information about the EDI, click here.
