Linked-Employer-Employee-Data of the IAB (LIAB): LIAB cross-sectional model 2 1993-2017, version 1

DOI: 10.5164/


The Linked-Employer-Employee-Data of the IAB (LIAB) combine interviews from the IAB Establishment Panel with the related establishment and individual data generated in labour administration and social security data processing. The latter cover administrative establishment information from the Establishment History Panel (BHP) and the employment biographies of individuals employed by the interviewed establishments. The LIAB data allow for simultaneous analysis of the supply and demand side of the German labour market.

Dataset Descriptions and Frequencies


Data Access

The Linked Employer-Employee Datasets are available via the following way of access:

  • On-site Use included Remote Data Access. Further information on Applying for on-site use. With your application to LIAB we provide automatically the IAB Establishment Panel, the administrative individual data and the basic module of the BHP. Further modules of BHP have to be requested explicitly in your application.

Test Data

Test data help to prepare programs ahead of on-site and remote data access. They are freely accessible over the web and therefore have to be anonymised. They shall reflect the structure of the original data as close as possible to be useful for many kinds of different analyses. As there are no universally useful test data we suggest that you adjust the test data for your purposes, e.g. if Spanish employees are in the focus of your investigation, just recode enough nationalities to Spanish.


Note: The test data for the IAB Establishment Panel are stored separately. It is possible to merge these test data with the test data for the respective LIAB model.
