Description
Statistics Canada is pleased to announce the release of the 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 between the Canadian Income Survey (CIS) and selected variables from the T1 Family File (T1FF) was performed. The current release is the result of a collaboration between the Center for Income and Socio-economic Well-being Statistics and the University of Toronto’s PROOF research program.
A deterministic 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
-
- Part 2 is a five-year retrospective linkage, which has CIS 2018 to 2022 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
-
- The analytical files available include selected variables from the T1FF and an anonymized key to join 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 (derived from both the tax filers and the non‑filers); variables are derived primarily from income tax returns.
