Agricultural Ecumene Census Division Boundary File 2001 Census of Agriculture
_____________________________________________________________________________

The agricultural ecumene for the 2001 Census of Agriculture was derived using 
agricultural data at the dissemination area level rather than the enumeration 
area level used in 1996. The dissemination area was introduced for 2001 as a 
new standard geographic area. It replaces the enumeration area as the basic 
building block for disseminating Census of Agriculture data. 

The agricultural ecumene product has three separate layers:
* the 2001 agricultural ecumene with integrated census division boundaries
* the 2001 census division boundaries
* the 2001 provincial/territorial boundaries.
In 1996, these three layers were combined into a single layer.

* For the first time the agricultural ecumene product is free on the Internet 
and includes a reference guide.
