Adjusted market income

Definition

'Adjusted market income' refers to market income of the statistical unit that is adjusted for economies of scale. The adjustment factor, also known as the equivalence scale, is the square root of the number of persons in the statistical unit. The adjusted market income is calculated by dividing the market income by this adjustment factor. The adjustment made to income addresses the fact that individuals living together can share resources and the marginal increase in need decreases as the number of individuals sharing resources increases.

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