| Abstract: | By the late 1970s, household telephone coverage grew to exceed90 percent in the United States, and by the mid-1980s telephonesurveying of the general public had become commonplace. Nevertheless,20 years later, the ability of researchers to reach representativesamples of the U.S. public via landline (wired) telephone surveysand gather reliable data is being seriously challenged for manyreasons, especially those related to cell phones and the growthof the "cell phone only" population. However, at present thereexists no widely accepted set of Cell Phone Surveying "bestpractices" for U.S. survey researchers to follow. Despite whatsome appear to believe, surveying persons reached on cell phonenumbers in the United States currently is a very complex undertakingif one wants to do it "right," i.e. to do it legally, ethically,and in ways that optimally allocate one's finite resources togather the highest quality data, and to analyze and interpretthose data accurately. This final "wrap-up" article in the specialissue provides a review of the empirical articles in the issuewith a focus on their practical implications for the decisionsthat researchers need to make regarding sampling, coverage,nonresponse, measurement, and weighting in surveys that includeinterviews with persons reached on cell phones. The articlealso highlights the practical implications of a number of legal,ethical, and other issues that relate to surveys in the UnitedStates that include cell phone numbers. Surveying the U.S. cellphone population is possible, if at a higher cost than surveyingtheir landline counterparts, and if with less precision thancurrently can be done surveying the landline population. Thenext five years should see a considerable growth in the methodologicaland statistical know-how that the survey community uses to plan,implement, and interpret cell phone surveys. There is a greatdeal that still must be learned. |
