More information on the data in the DS NMDS are contained in the associated DS NMDS collection materials, or METEOR and the associated DS NMDS report.

Note that, as part of the DS NMDS process, from 2007–08 jurisdictions can revise their data for the previous year at the time of submitting their current year. Reasons for resubmission include data updates or subsequent discovery of data errors. For this reason, data presented here may not match that presented in published reports for those years in which data has been revised.
