Fewer that 10% of those contacted bother to complete a political poll. But pollsters say that doesn’t really affect the results.
The Pew Research Center’s latest detailed study of survey quality paints a worrisome picture for survey response rates, but again shows that a well-done telephone poll — even one with response rates in the high single-digits — accurately represent the U.S. population on a broad range of political and demographic measures. The apparent accuracy of results from a survey where fewer than one in 10 people completed the interview parallels previous studies showing a weak connection between response rates and survey quality. A 2008 study of more than 100 surveys, including many media polls, concluded that “lower response rates do not notably reduce the quality of survey demographic estimates.”
Do you hang up on pollsters?
