EXAMPLE 3.12 Change in Nonresponse in Pew Surveys

The Pew Research Center conducts research using surveys on a variety of issues, attitudes, and trends.16 A study by the center examined the decline in the response rates to their surveys over time. The changes are dramatic, and there is a consistent pattern over time. Here are some data from the report:17

Year 1997 2000 2003 2006 2009 2012
Nonresponse rate 64% 72% 75% 79% 85% 91%

The center is devising alternative methods that show some promise of improving the response rates of their surveys.
