Employment income decile group

Release date: November 17, 2021Updated on: July 13, 2022

Definition

The employment income deciles divide the population aged 15 years and over with employment income (positive or negative) into 10 equal-sized groups according to the rank of the employment income. Those in the bottom decile group are the ones who fall in the lower 10 percent of the employment income distribution. Those in the top decile group are the ones who fall in the highest ten percent of the employment income distribution.

For the 2021 Census, the reference period for income data is the calendar year 2020, unless otherwise specified.

Remarks

Persons without employment income are excluded from the calculation of the deciles cut-points (i.e., the levels of employment 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%.
