Low-income cut-offs, after tax (LICO-AT)

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


The Low‑income cut‑offs, after tax refer to income thresholds, defined using 1992 expenditure data, below which economic families or persons not in economic families would likely have devoted a larger share of their after‑tax income than average to the necessities of food, shelter and clothing. More specifically, the thresholds represented income levels at which these families or persons were expected to spend 20 percentage points or more of their after‑tax income than average on food, shelter and clothing. These thresholds have been adjusted to current dollars using the all‑items Consumer Price Index (CPI).

The LICO‑AT has 35 cut-offs varying by seven family sizes to account for economies of scale and five different sizes of area of residence to account for potential differences in cost of living in communities of different sizes. These thresholds are presented in Table 2.5 Low‑income cut‑offs, after tax (LICO‑AT ‒ 1992 base) for economic families and persons not in economic families, 2020, Dictionary, Census of Population, 2021.

When the after‑tax income of an economic family or a person not in an economic family falls below the threshold applicable to the person, the person, or every member in the case of an economic family is considered to be in low income according to LICO‑AT. Low‑income status is typically presented for persons but, since the LICO‑AT threshold and family income are unique within each economic family, low‑income status based on LICO‑AT can also be reported for economic families.

For the 2021 Census, the reference period for low‑income data is the calendar year 2020.

The first set of Low‑income cut‑offs, after tax was based on income data and family expenditure patterns in 1986. The most recent Low‑income cut‑offs, after tax are based on the 1992 Family Expenditure Survey, which estimated that families spent on average 43% of their after‑tax income on necessities of food, clothing and shelter. The LICO‑AT thresholds were thus set to income levels where 63% of after‑tax income would likely be spent on these necessities. Cut‑offs for any given reference year are indexed by applying the corresponding annual all‑items Consumer Price Index (CPI) to the cut‑offs from the 1992 base year.

Low‑income cut‑offs, after tax is one of a series of low‑income lines used in the Census.

See also low‑income status; prevalence of low income; low‑income gap; low‑income gap ratio and after‑tax income.

Note that persons living in collective households are considered out of scope, as in the past Censuses, for all of the low‑income concepts because their living arrangements and expenditure patterns can be quite different from those of persons living in private households.

The LICO low‑income concept is also not applied in the territories and on reserve because the original evaluation of income and expenditure patterns was not conducted in those areas.

Since the initial publication of the low‑income lines, Statistics Canada has clearly and consistently emphasized that poverty is not something that can be defined by a National Statistical Organization. Instead, defining poverty is the responsibility of the policy departments of the government. In 2018, the Government of Canada released Opportunity for All – Canada's First Poverty Reduction Strategy. In this report, it was recognized that poverty is a multifaceted problem that goes beyond not having enough income. Based on the recommendation of this strategy, the government designated, the Market Basket Measure of low income as Canada's official poverty line under the Poverty Reduction Act in 2019. For more information about the official poverty line, see Market Basket Measure (MBM).

As a statistical agency, Statistics Canada's role is to publish measures of low income based on consistent and well‑defined methodology and to update these measures to reflect the current state of the Canadian society and economy. These measures would allow for the reporting of important trends in low income and economic well‑being, such as identifying those who are substantially worse off than average and tracking the changes in composition of those below any given low‑income or poverty line over time.

For additional information on various low‑income concepts, see 'Low Income Lines: What they are and how they are created' and 'Low Income in Canada - A Multi‑line and Multi‑index Perspective' in the Income Research Paper Series (Catalogue no. 75F0002M).
