The planning and the editing of the omnibus surveys is a joint effort by the Danish National Institute of Social Research and Danmarks Statistik. The interviewing takes place over a period of 2-3 weeks, and the total interview time is usually between 45 minutes and one hour per interview. Before the interviewing starts instruction meetings are held at which the questions are examined thoroughly and the interviewers are informed about the subjects covered in the survey.
