The survey waves of the German Internet Panel are conducted every other month. The questionnaires cover topics such as attitudes towards political reforms, the welfare state, German and EU politics, health, social inequality, education, and employment. In addition, the core wave that takes place annually in September collects and updates key socio-demographic information.
