Methods can matter: Where Web surveys produce different results than phone interviews
A Pew Research Center experiment found several key areas where Web surveys produced different results than those conducted by phone.
How to access Pew Research Center survey data
Earlier in January, the Pew Research Center released the full dataset from our largest study ever conducted on U.S. politics, the 2014 Political Polarization and Typology survey, to make it available to researchers. Here’s how you can access that dataset, as well as our others.
Pew Research will call more cellphones in 2015
An estimated 46.5% of U.S. adults are cell-only today. To keep pace with this trend, the Pew Research Center will increase the percentage of respondents interviewed on cellphones in its typical national telephone surveys to 65%.
Q/A: How Pew Research created the political typology
The goal of the political typology is to sort people into homogeneous groups, based on their political values and attitudes. It’s an effort to categorize people politically to help us better understand the complexities of the current political landscape.
Pew Research increases share of interviews conducted by cellphone
In the coming months, 60% of interviews in our national polls will be conducted via cellphones and 40% on landline phones.
