Weighting to adjust for non-observation errors in telephone surveys

Abstract

Introduction: For its social and demographic surveys, Statistics Netherlands favours CAPI over cheaper modes that employ web or telephone. Due to the persuasive power and assistance of interviewers visiting selected persons or households, nonresponse in CAPI surveys is relatively low and data quality is high. However, the costs of this mode of interviewing are relatively high. A large group of trained interviewers is required. Although the Netherlands is a small country, travel costs make up a considerable proportion of the total costs.
