Statistics Canada is pleased to announce the availability of a new linkage key files [1]: the Longitudinal Administrative Databank (LAD) and the 2016 Census of population long form data; and the LAD and the 2021 Census of population long form.
The available microdata contains anonymized identification number for the LAD from 1982 to 2021 (20% of tax filers) linked to the 2016 and to the 2021 respondents to the census of population. To access actual information, researchers will need to link the LAD and appropriate census data using these linkage key files. It is important to note that the linkage keys should not be used to link census data from 2016 and 2021 together.
Researchers will find useful to combine longitudinal income tax data with detailed characteristics on various topics available in the Census of population long form database.
The data dictionary of each of the three data source should be consulted for detailed content of the data sources.
