Abstract

The size of the cell-telephone-only population has increased rapidly in recent years and, correspondingly, researchers have begun to experiment with sampling and interviewing of cell-telephone subscribers. We discuss statistical issues involved in the sampling design and estimation phases of cell-telephone studies. This work is presented primarily in the context of a nonoverlapping dual-frame survey in which one frame and sample are employed for the landline population and a second frame and sample are employed for the cell-telephone-only population. Additional considerations necessary for overlapping dual-frame surveys (where the cell-telephone frame and sample include some of the landline population) will also be discussed. We discuss the linkages that must be identified and made between the various sampling, estimation, and other intermediate units. We discuss the concept of usual place of residence, which links the person to the housing unit, and the concept of usual access to the telephone, which links the person to the cell-telephone line(s). We highlight the questions that must be asked and answered in both the landline interview and the cell-telephone interview in order to identify the critical linkages. We present estimators of population totals at both the household and person level, and we set forth the set of weights that are needed to support the unbiased estimator. We demonstrate a complete set of weighting steps, including adjustments for nonresponse (including inaccessibility) and calibration to known population totals. These sampling and estimation issues are applied to hypothetical cell-telephone supplements to the National Immunization Survey (NIS), which monitors the vaccination rates of children age 19-35 months and 13-17 years, and the National Survey of Children’s Health (NSCH). Both surveys are nationwide, list-assisted random-digit-dialing surveys conducted by the National Opinion Research Center for the Centers for Disease Control and Prevention.
