Updates to the Canadian Income Survey (CIS) linked to T1FF are now available in Research Data Centres across Canada.

Statistics Canada announces the release of updated analytical files for the project Food insecurity and income using the Canadian Income Survey (CIS) and T1 Family Files (T1FF).  For this project, a linkage was conducted between the Canadian Income Survey (CIS) and selected variables from the T1 Family File (T1FF) was performed. The project is the result of a collaboration between the Centre for Housing and Income Statistics and the University of Toronto’s PROOF research program.

A linkage between the CIS and selected variables from the T1FF has been performed in two parts.

Part 1 linkage uses a single year of data from the CIS and the T1FF. The linkage structure is as follows:

-CIS 2018 linked to T1FF 2019

-CIS 2019 linked to T1FF 2020

-CIS 2020 linked to T1FF 2021

-CIS 2021 linked to T1FF 2022

-CIS 2022 linked to T1FF 2023

Part 2 is a five-year retrospective linkage, which has CIS 2018 to 2023 linked to T1FF for five previous years:

-CIS 2018 linked to T1FF 2013, 2014, 2015, 2016, 2017

-CIS 2019 linked to T1FF 2014, 2015, 2016, 2017, 2018

-CIS 2020 linked to T1FF 2015, 2016, 2017, 2018, 2019

-CIS 2021 linked to T1FF 2016, 2017, 2018, 2019, 2020

-CIS 2022 linked to T1FF 2017, 2018, 2019, 2020, 2021

-CIS 2023 linked to T1FF 2018, 2019, 2020, 2021, 2022

The analytical files available include selected variables from the T1FF and an anonymized key to join individual records to the CIS. The following information is available from each respective source of data:

• Canadian Income Survey provides information on the income and income sources of Canadians, along with their individual and household characteristics.
• T1 Family File provides information on sources of income (from the tax filers) and some demographic indicators (present for both tax filers and non‑filers); variables are derived primarily from income tax returns.
