Overview

Summary

The Longitudinal Worker File (LWF) is an administrative database designed to provide information on employment dynamics in Canada. From the linked administrative tax data sources, information on workers’ demographic characteristics, the jobs they hold, the business enterprises in which they work, and the earnings they receive can be identified. This structure, coupled with information that allows workers’ movements from employer to employer be identified, makes the LWF particularly well-suited to studying a variety of issues (e.g., labour turnover and mobility, earnings dynamics, and transitions to retirement). The LWF-RDC file is a version of the LWF 100% file that can be accessed by researchers at the Research Data Centres (RDCs). This LWF-RDC version 1.0 covers tax years between 1991 and 2016 with the following key features: A 10% file extracted from the LWF 100% file. A generic firm ID is created to identify the same firm that individuals are associated with so that individual job mobility can be tracked but information cannot be aggregated at the firm-level. Industry information associated with each job record will be provided at aggregate level (2-digit NAICS level from 1991 onwards).
