Nick Bertoni, manager of the American Trends Panel, explains how the panel works and what its recent expansion means for our future survey work.
Pew Research Center’s American Trends Panel (ATP) is now the Center’s principal source of data for U.S. public opinion research.
Response rates to telephone public opinion polls conducted by Pew Research Center have resumed their decline, to 7% in 2017 and 6% in 2018.
What does the migration to online polling mean for the country's trove of public opinion data gathered over the past four decades?
Pew Research Center conducts surveys over the phone and, increasingly, online. But these two formats don’t always produce identical results.
Evolution remains a contentious issue. When asked about it, highly religious Americans' responses can vary depending on how the question is asked.
The way polling questions are asked can influence people's answers. Survey experiments are one way to measure the degree to which different questions elicit different answers.
Pew Research Center uses benchmarking questions to ensure our surveys are accurate. Learn why and how we use these questions.
On election night 2018, besides the exit polls there will be an additional source of data on who voted and why, developed by The Associated Press, Fox News and NORC at the University of Chicago and based on a very different methodology. That means that depending on where you go for election news, you may get a somewhat different portrait of this year's electorate.
Given the wide range of people we speak to for our polls – and the issues we ask them about – it’s important to be as clear as possible about exactly who says what. In research circles, this practice is sometimes called “defining the universe."
