Longitudinal Administrative Databank

Overview

Summary

The Longitudinal Administrative Databank (LAD) is a longitudinal file designed as a research tool on income and demographics. It comprises a 20% sample of the annual T1 Family File (record number 4105) and the Longitudinal Immigration Data Base (record number 5057). Variables have been harmonized where possible and individuals can be linked year to year starting with 1982 data. The file is augmented annually with new data. The longitudinal file contains many annual demographic variables about the individuals represented and annual income information for both the individual and their census family in that year. For immigrants landed between 1980 and 2014, the file also contains certain key characteristics observed at landing. The longitudinal nature of the LAD permits custom-tailored research into dynamic phenomena, as well as representative cross-sectional patterns. Data are mainly used by government departments to evaluate programs and support policy recommendations. Academics, private consultants and Statistics Canada researchers also use the data for analyses of socio-economic conditions.

A supplementary list of firm-level variables is linkable to the LAD to facilitate an understanding of the labour market connection for individuals in the LAD. These variables are drawn from the Canadian Employer-Employee Dynamic Database. A linkage key is also available to join the landing records from the IMDB to to the LAD.

A linkage to the T1FF Schedule 3 (Capital gains) is also available.
