When working with Census geography, everywhere is somewhere. For Nova Scotia, the 2016 Census reference maps at the Aggregate Dissemination Area (ADA) and Dissemination Area (DA) geographic levels are now publicly available through the Dalhousie University Dataverse <https://dataverse.library.dal.ca>.
These are PDF files from Statistics Canada that define ADA and DA boundaries for all eighteen counties in Nova Scotia. DAs (formerly Enumeration Areas), have been used since the 2001 Census, but ADAs are new. They were created for the 2016 Census to encompass areas having a population ideally between 5,000 and 15,000, and cover an entire county (respecting its boundary).
The number of ADAs reflect the overall population of each county. Halifax County has 57 ADAs whereas Guysborough County has only one. Each county is a Dataverse dataset with its own Readme file, providing the coding correspondence between each ADAuid and DAuid. These identifiers are defined in the Readme file. In addition, there are CT maps that define the Census Tracts for the Halifax Census Metropolitan Area (CMA=205). Overall, this collection contains more than a thousand maps (PDF files). You can download one or more files.
Note: The DA reference maps are not available on the StatCan website but the Statistics Canada Open Licence enables us to distribute this collection of maps on an “as is” basis.
Special thanks to Sai Chua and Lachlan MacLeod for all of their work on this!
