AAPOR Cell Phone Task Force Report

- October 30, 2010

Find it “here”:http://aapor.org/Cell_Phone_Task_Force.htm. A central conclusion:

bq. In terms of Sampling and Coverage, good RDD cell phone samples are available for researchers to use. The cell phone RDD frame has been demonstrated consistently to provide better coverage of a number of important demographic groups in the U.S. than the landline RDD frame. However, to date, cell phone RDD samples for the U.S. are not as efficient as landline RDD samples, for many reasons. Possibly the most basic decision that researchers need to make is whether they will use a cell phone sample to supplement a landline sample and if so whether the dual frame design will be overlapping (with no screening for telephone service and usage) or nonoverlapping (e.g., screening the cell phone sample for cell phone only persons/households). The Task Force believes at this time that neither of these two basic dual frame designs is always the preferred one for researchers to choose. That may change in the next few years, but for now researchers need to think very carefully about how to best balance the many issues and implications associated with their sampling design decisions.
