Rounding

Totals may not equal the sum of their parts due to the use of conversion factors or rounding of fractions to whole numbers.

Headquarters rule

Many agricultural operations in Canada are composed of numerous parcels of land in a number of locations. These different locations are often situated in several geographic areas (such as townships or counties). In these situations, the "headquarters rule" assigns all data collected for the agricultural operation to the geographic area where the farm headquarters is located.

Incomplete enumeration of Indian reserves and Indian settlements

On some Indian reserves and Indian settlements in the 2001 Census, enumeration was not permitted or was interrupted before it could be completed. Moreover, for some Indian reserves and Indian settlements, the quality of the enumeration was considered inadequate. These geographic areas (a total of 30) are called incompletely enumerated Indian reserves and Indian settlements.

Data for census farms located on these incompletely enumerated reserves and settlements are therefore not available. The impact of the missing data is very small for higher-level geographic areas (Canada, provinces, and census agricultural regions). However, the impact is more significant for those smaller areas (census divisions and census consolidated subdivisions) in which the affected reserves and settlements are located.
