Survey Says....Declining Survey Response Rate Makes No Difference in Accuracy of Information

Survey contact, cooperation, and response rates, 1997-2012

9% - Pollsters Face Challenges in Getting Survey Respondents. (Pew Research Daily Number, 5/25/2012)

Excerpt    These challenges have led many to question whether surveys are still providing accurate and unbiased information. But a new study by the Pew Research Center for the People & the Press finds that, despite declining response rates, telephone surveys that include landlines and cell phones and are weighted to match the demographic composition of the population continue to provide accurate data on most political, social and economic measures. This comports with the consistent record of accuracy achieved by major polls when it comes to estimating election outcomes, among other things.

As much as I respect Pew Research, isn't this a variation of the fox watching the henhouse?
