Total income decile group
Total income decile group
Definition
The total income deciles divide the population aged 15 years and over into 10 equal-sized groups according to the rank of the total income. Those in the bottom decile group are the ones who fall in the lower 10 percent of the total income distribution. Those in the top decile group are the ones who fall in the highest ten percent of the total income distribution.
For the 2021 Census, the reference period for income data is the calendar year 2020, unless otherwise specified.

Remarks
Persons without total income are included in the calculation of the deciles cut-points (i.e., the levels of total income that define the decile groups).
Since the deciles cut-points are derived based on data from the 2021 Census of Population short-form questionnaire, the percentage of the sampled population in each decile group may not correspond exactly to 10%.
