Census of Agriculture Missing Data at CCS Level

Question

One of our biology researchers is using the DLI Census of Agriculture 2001 B2020 tables for a GIS research project and has reported that the tables are consistently missing Consolidated Census Subdivisions (CCS).

Specifically, a total of 138 Consolidated Census Subdivisions are missing from the b2020 tables across Atl, Que, Ont, MSk, & ABC, e.g., TABLE3Atl, TABLE3Que, TABLE3Ont, TABLE3MSk, TABLE3ABC and are not accounted for by the documented CCS amalgamations. The researcher has tested and found this consistently for tables 3, 28 and 32 and wishes to know:

Have the 138 attached CCS’s been amalgamated, but not documented? If so, what are the correct CCS’s to use? If the 138 attached CCS’s have not been amalgamated, have they been suppressed, or can they be obtained through means other than the DLI B2020 files? Please provide some detail for methodology documentation / follow-up purposes.

Answer

Some of the CCS's in the list were checked and found to have zero farms.

If you have the reference maps from 2001 at bottom of the list of CCS within Census Divisions (after the maps) you will find the note "all Census Consolidated Subdivisions in italics had no farms in 2001". If you don't have the reference maps they are found at www.statcan.ca under census, under 2001 census, under census of agriculture, under farm data, and under reference maps.
