The Census Dictionary is a reference document which contains detailed definitions of Census of Population concepts, universes, variables, and geographic terms, as well as historical information.

By referring to the Census Dictionary, both beginner and intermediate data users will gain a better understanding of the data and how to compare variables between census years.

The continued effort to include supplementary shorter definitions for certain variables, using plain language without census or Statistics Canada jargon, will further help users better understand the meaning of the definitions found within the Census Dictionary and elsewhere within the census module.
