Second European Union minorities and discrimination survey : technical report

FRA's Second European Union Minorities and Discrimination Survey (EU-MIDIS II) surveys around 26,000 individuals from different ethnic minority and immigrant backgrounds across all 28 EU Member States. This technical report presents a detailed overview of the research methods used by FRA when collecting the survey data. This technical report provides the relevant information needed to assess the quality and reliability of the EUMIDIS II survey data, as well as considerations for interpreting the survey results. Survey researchers often assess quality in terms of absence or presence of various types of bias, which affect all surveys. The various sections of this technical report clearly identify potential sources of bias, stemming from survey design or decisions made when implementing the survey. Given the innovative nature of the survey and the advanced methods used in balancing costs with potential sources of bias, this report can also be used as a reference when developing other national or multinational surveys on immigrants and ethnic minorities. The following chapters of the report cover the procedures used in the development and administration of the survey.
