Calling Effort and Nonresponse for Telephone Panel Surveys

Roberta L. Sangster


For this study, I examine how nonworking numbers, noncontacts (basically answering machines, scheduled callbacks, and ring-no-answer numbers impact the number of completed interviews across time and also the amount of effort involved to contact the telephone numbers based on the number of call attempts. The analysis presented in this paper is only descriptive, no statistical tests are used.
