by Laurie R. Kuslansky, Ph.D. Managing Director, Jury Consulting A2L Consulting Research has shown that a variety of individuals are not fully represented in telephone surveys, especially Democrats, the young, nonwhite, and urban voters who can be the hardest for pollsters to reach. In addition, the migration from landline phones associated with home addresses to portable cell phones unrelated to home addresses compounds the problem of reaching and surveying a representative sample using traditional approaches to phone surveys. And, not all venues were created equally. Some have more hard-to-reach residents, while some have more cell phones replacing landlines. In general, “It has become increasingly difficult to contact potential respondents and to persuade them to participate,” dropping from 36% in 1997 to 9% now willing to participate in phone surveys.
