What our transition to online polling means for decades of phone survey trends
What does the migration to online polling mean for the country’s trove of public opinion data gathered over the past four decades?
Telephone polls still provide accurate data on a wide range of social, demographic and political variables, but some weaknesses persist.
Online nonprobability surveys are fast, cheap, and increasingly popular. We compared nine samples and found that accuracy varied substantially.
The claim by Kuriakose and Robbins (2015) that there is widespread falsification in international surveys is clearly concerning. However, an extensive investigation conducted by Pew Research Center finds the claim is not well supported.
