*The frequency of data collection varies across jurisdictions. Some jurisdictions have a 1-year data collection period, while others have a collection period of 2 or more years.

The proportion of children age 5 who are vulnerable on one or more of the domains on the Early Development Instrument (EDI)** score varies between provinces and territories.

38.1% were vulnerable in the Northwest Territories and 17.2% were vulnerable in Prince Edward Island.

There are differences between how the EDI is administered between provinces and territories, as well as differences in how often it is administered. Therefore, the time period is not uniform – this needs to be considered when looking at differences across province/territories.
