Extending the Relevance of the Longitudinal Files (ERLF)

  1. National Population Health Survey (NPHS) – Linked to T1 Family file (T1FF) and the Canadian Vital Statistics Deaths Database
  2. Survey of Labour and Income Dynamics (SLID) - Linked to T1 Family File (T1FF), Canadian Vital Statistics Deaths Database and Canadian Cancer Registry
  3. Youth in Transition Survey (YITS) - Linked to T1 Family File (T1FF)
  4. National Longitudinal Survey of Children and Youth (NLSCY) – Linked to T1 Family File (T1FF)

Longitudinal data allow researchers to be able to better understand the factors behind events or problems. Given the importance of longitudinal data in research, it was important to find a way to extend the usefulness of Statistics Canada's longitudinal data for research purposes.

For this project, outcome files were created by adding variables from newer data files and the survey identifier from the original longitudinal files. Researchers will need to merge the longitudinal file with these outcome files to build a linked analysis file for analytical purposes.

Instructions for merging files is provided in the user guide. Additional documentation on the selected T1FF outcome variables is available in the RDCs to researchers with approved projects. Metadata on the Canadian Vital Statistics – Deaths and the Canadian Cancer Registry variables are also available in the RDCs.

The variables that are included in the outcome files are:
