In 2005, two new sub-samples, who were selected among respondents in the 2004 survey and were living in seven of the most deprived and seven of the most affluent neighborhoods of Eindhoven, were invited for an interview. This in-depth interview provided information about socioeconomic position, SEP-related information, health behaviors, material factors, psychosocial factors, cultural factors, youth circumstances, sociodemographics and the built environment.

Information from the survey has been linked to three main databases: the Cause-specific death registers from Statistics Netherlands; the National Medical Register including hospital admission information from all Dutch individuals; and the Regional Cancer Surveillance South.
