Low-income status of economic family

Status: This standard was approved as a departmental standard on July 31, 2026.

Definition

Low-income status refers to the income situation of the statistical unit in relation to a specific low-income line in a reference year. Statistical units with income that is below the low-income line are considered to be in low income.

Economic family refers to a group of two or more persons who live in the same household and are related to each other through biological, couple, adoptive or foster relationships.

Examples of an economic family include two co-resident census families who are related to one another, co-resident siblings who are not members of a census family, or a niece or nephew living with their aunt or uncle.

All members of a given census family belong to the same economic family, as well as any other household members who are related to at least one member of the census family. In households with no census families present, all related persons in the household form an economic family.

Usage

The prevalence of low income is the number or percentage of economic families in low income.

Beyond the prevalence of low income, various low-income indicators can be derived and used to capture the depth of low income.

The low-income gap measures by how many dollars an income falls below a low-income line. The low-income gap ratio expresses the low-income gap as a proportion of the applicable low-income line.

Statistics such as average and median of the gap and gap ratio provide measures of depth of low income for the low-income population.

For those who are not in low income, the gap and gap ratio would have a value of zero. For those who are in low income with no or negative income, the gap is set to be the amount specified by the applicable low-income line. The gap ratio indicator would thus be equal to 1.

Low-income status for economic families is typically measured using three low-income concepts. For more information on these concepts, refer to the Measurements section.

Measurements

  • 'Market Basket Measure (MBM)' refers to Canada's official measure of poverty, which is based on the cost of a specific basket of goods and services representing a modest, basic standard of living. The MBM thresholds represent the cost of a basket of food, clothing and footwear, shelter, transportation, communication services, and other expenses for the MBM reference family in each MBM region. The square root of economic family size is the equivalence scale used to adjust the MBM thresholds for other family sizes. This adjustment for different family sizes reflects the fact that a family's needs increase, but at a decreasing rate, as the number of members increases. June 09, 2026 to current
  • 'Low-income cut-offs, after-tax (LICO-AT)' refers 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). March 21, 2016 to current
  • 'Low-income cut-offs, before-tax (LICO-BT)' refers 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 total 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 total income than average on food, shelter and clothing. These thresholds have been adjusted to current dollars using the all-items Consumer Price Index (CPI). March 21, 2016 to current

Additional information

As a statistical agency, Statistics Canada's role is to publish measures of poverty and 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 allow for the reporting of important trends in poverty, 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 poverty or any given low-income line over time. See "Low Income Lines: What they are and how they are created" and "Low Income in Canada - A Multi-line and Multi-index Perspective" from the Income Research Paper Series for detailed definitions and discussions of each line.

In 2018, the Government of Canada released "Opportunity for All - Canada's First Poverty Reduction Strategy". 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, and set poverty reduction targets for 2020 and 2030 that aligned with the United Nations Sustainable Development Goals to end poverty. Progress on meeting these targets is discussed in "We can do better: it is not a safety net if the holes are this big - the 2025 report of the National Advisory Council on Poverty".

The MBM was developed by Employment and Social Development Canada (ESDC) and Statistics Canada. Full details on the current MBM methodology adopted upon the completion of the third comprehensive review of the MBM can be found in the article 'The proposed methodology for the 2023-base Market Basket Measure of poverty' housed within the Dimensions of Poverty Hub.

Of the 3 measures, only the MBM is applicable in the territories. None of these measures are applied for on-reserve geographies. Statistics Canada defines income in the same way on and off reserve, which provides a common conceptual base upon which income comparisons can be made. However, income statistics explicitly exclude certain sources of income, such as the value of food produced for own consumption, and the value of subsidized housing. The importance of these exclusions can differ from region to region, and they may be more important to the on-reserve (and territorial) than the off-reserve populations. Likewise, although tax-exempt income earned on reserve is included in the income concept, and captured through the T1, T4 and other government-provided slips, Statistics Canada is unable to measure all tax-exempt income on reserve.
