• Telephone survey response rates have plummeted over the past 20-odd years, but may have reached their floor, according to a Gallup study whose results are supported by other research.
  • Cellphone response rates had also dropped during the same period, from 11.7% to 7%. Meanwhile, a study released last year by the Pew Research Center found that response rates for landline telephone polls had dropped dramatically from 36% in 1997 to 9% in 2012.
  • Recently, separate Gallup research found that a large US university’s alumni survey – a web survey – achieved a response rate of 14%, aided by above-average response rates among those provided with a $5 incentive.
