Is there a variable which measures ethnicity?

The variable "herkomstgroep" measures ethnicity in several broad categories. It is part of the Background Variables of the LISS panel and Immigrant panel. The core study Religion and Ethnicity also includes several indicators of ethnic background. A more detailed ethnicity variable, "herkomstland", is only available for the Immigrant panel in the Background Variables. It is published from September 2011 up until December 2014. We do not provide more detailed information about the ethnicity of the respondents because of privacy reasons/identification risk.
