Linked to T1 Family File (T1FF)

This data release is part of a collaborative project titled Food Insecurity and Income, conducted by Statistics Canada, the Center for Income and Socio-economic Well-being Statistics, and the University of Toronto’s PROOF research program.

It combines key information from the Canadian Income Survey (CIS)—which tracks Canadian incomes, income sources, and household characteristics—with selected variables from the T1 Family File (T1FF)—which contains income and some demographic details drawn primarily from income tax returns.

Linkage overview

Two types of data linkages were performed:

Part 1 (single-year linkage)

• CIS 2018 linked to T1FF 2019
• CIS 2019 linked to T1FF 2020
• CIS 2020 linked to T1FF 2021
• CIS 2021 linked to T1FF 2022

Part 2 (five-year retrospective linkage)

• CIS 2018 linked to T1FF 2013–2017
• CIS 2019 linked to T1FF 2014–2018
• CIS 2020 linked to T1FF 2015–2019
• CIS 2021 linked to T1FF 2016–2020
• CIS 2022 linked to T1FF 2017–2021

These linkages allow researchers to explore household income patterns and food insecurity over multiple years, providing a more in-depth look at the economic well-being of Canadians.

Data contents

From CIS: Comprehensive information on Canadians’ income, sources of income, and various personal or household characteristics.

From T1FF: Details on income derived from tax returns (for both filers and non-filers) and limited demographic indicators.

Availability and future updates

The analytical files (with selected T1FF variables and an anonymized key to link with the CIS) are now available and are scheduled for an update by the end of 2025.

To apply for access to these microdata, see the Microdata Access Portal (MAP). Non-confidential documentation can be requested from your local RDC Analyst.

By combining survey information with administrative tax data, these linked files provide valuable insights into the financial well-being of Canadians and the factors that may influence food insecurity.

Data linked to T1FF

This custom microdata file was created by Statistics Canada, in partnership with Employment and Social Development Canada (ESDC).

It brings together selected income information from the T1 Family File (T1FF) from 2017 through 2022 and includes both individuals with disabilities and those without disabilities from the 2022 Canadian Survey on Disability (CSD).

By combining income data with disability status, the file supports a more detailed understanding of various social and economic factors affecting Canadians.

This linked dataset is intended to be used alongside the complete set of 2022 CSD Analytical Data Files, enhancing the overall depth and quality of analysis related to disability and income in Canada.

The Consumer Price Index (CPI) represents changes in prices as experienced by Canadian consumers. It measures price change by comparing, through time, the cost of a fixed basket of goods and services.

Since the basket contains goods and services of unchanging or equivalent quantity and quality, the index reflects only pure price change. The CPI is widely used as an indicator of the change in the general level of consumer prices or the rate of inflation.

Since the purchasing power of money is affected by changes in prices, the CPI is useful to all Canadians. Consumers can compare movements in the CPI to changes in their personal income to monitor and evaluate changes in their financial situation.

The survey asks parents and guardians about the arrangements they use for their child aged zero to five, including the associated costs, the difficulties they may have faced when looking for care, and what their preferences for child care are.

This survey also collects information on parents' and guardian's labour market participation to better understand the interaction between work and the use of early learning and child care arrangements.

Results from this survey will be used to help improve the Canada-wide early learning and child care system and provide Canadians with a strong baseline of data to measure progress and changes to the system.

The main objective of the CHIRP (Children with Incarcerated Parents) Study is to identify children who experience parental incarceration, using data from the Canadian Correctional Services Survey (CCSS) 2015-2022, the Canadian Vital Statistics database 1997-2022 and the Discharge Abstract Database 1997-2022.

Through this data linkage, an estimate of the actual number of children experiencing parental incarceration can be determined, as well as he health status and outcomes of this population relative to general population. This project will address data gaps regarding the lack of population-level data on the number of children who experience parental incarceration.

The findings of this project could be used to increase the visibility of this population in national and provincial policies, and ultimately to inform the design and delivery of initiatives to better support children who experience parental incarceration.
