Total income decile group

Release date: May 3, 2017 Updated on: September 13, 2017


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.

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 2016 Census of Population short-form questionnaire, the percentage of the sampled population in each decile group may not correspond exactly to 10%.

See also total income.

For the 2016 Census, the reference period is the calendar year 2015 for all income variables.

For additional information about data collection method, coverage, reference period, concepts, data quality and intercensal comparability of the income data, refer to the Income Reference Guide, Census of Population, 2016.
