Abstract

Roberta L. Sangster (2002) "Calling Effort and Nonresponse for Telephone Panel Surveys."

Over several years, I have been working with issues related to RDD (Random Digit Dialed) generated telephone survey panels and attrition rate calculations. 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. Opinions and errors are the sole responsibility of the author and do not represent opinions of the Bureau of Labor Statistics.
