Linked Employer-Employee Database (LEED)
What is LEED?
The Linked Employer-Employee Dataset (LEED) brings together employer information (from the Business Longitudinal Analysis Data Environment) and employee information (from Personal Income Tax data) into a linked dataset, made possible through data integration.
LEED covers six consecutive financial years - 2011-12 through to 2016-17 and is updated annually.
How does it work?
The linked dataset is comprised of a person file, a job file, and an employer file. Employed persons are linked to employers via jobs. A person can have a number of jobs throughout the year with one or many employers, some of which may be held concurrently.
LEED enables detailed analysis of the Australian labour market, particularly at small geographic levels. Information is available across the three lenses of jobs, persons and employers.
- Jobs - provides information on the more than 100 million jobs held in Australia (ranging from 18 to 19.2 million each year), such as when they were worked, how much they paid, as well as the characteristics of the businesses that offered them and the people who worked in them, enabling detailed analysis that has not previously been possible
- Persons – provides new insights on topics such as multiple job-holding in Australia (how many people are working more than one job at a time and what type of jobs they are working), as well as analysis of jobs by a number of detailed characteristics such as age, sex, geography, occupation, and industry
- Employers - by linking employee microdata directly to employer information, it provides further insights into topics such as job creation and destruction as industries change over time, and elements that assist in exploring the drivers of firm-level performance, such as occupation composition and the key demographics of employees
Research benefits and outcomes
Researchers have already used data from LEED to study micro-labour markets, examine how specific major changes impact employees and employers, and understand structural changes in the labour market.
Some examples of important insights made possible by LEED can be found in the Jobs in Australia release.
Information from LEED is used in the compilation of the Australian Labour Account. Methodology developed for LEED is used in the Weekly Payroll Jobs and Wages in Australia publication, part of the ABS response to Covid-19.
