The WageIndicator websites, run by the non-profit WageIndicator Foundation, post frequently searched information about national labour laws, minimum wages, occupation-specific salary information, collective agreements, vacancies, and the like.

The WageIndicator Foundation’s Board of Supervisors is chaired by Amsterdam Institute for Advanced Labour Studies (AIAS), University of Amsterdam.

In 2015, the Foundation operates national websites in 85 countries, attracting 24 million unique visitors. On each website a web survey is posted, inviting visitors to complete the survey with a lottery prize.

The main characteristics of the WageIndicator web survey are:

  • The topics relate to wages and working conditions
  • The target population is the labour force, including employees, self-employed, informal workers, job seekers and the unemployed
  • The respondents are volunteers recruited through the national WageIndicator websites and a wide range of websites of WageIndicator partners, hence this is a non-probability survey and not representative of the target population
  • The web survey is posted continuously and generates large sample sizes
  • APIs are exploited for the survey questions about occupation, education and region
  • For academic researchers the dataset is freely available from the IZA data archive, Bonn, Germany. Click here for the extensive codebook. Click here for research publications related to WageIndicator

The WageIndicator Survey’s expertise around socio-economic coding forms the basis for WP8: A coding module for socio-economic survey questions.
