Telephone surveys face numerous challenges, but some positive developments have emerged, principally with respect to sampling.
Surveying Hispanics is complicated for many reasons – language barriers, sampling issues and cultural differences – that are the subject of a growing field of inquiry.

Respondents who take a Pew Research Center survey on a cellphone are currently offered reimbursement for their cellphone minutes for completing the survey. But is it still necessary in the age of unlimited talk and text?
With so many respondents taking Web surveys on smartphones, creating surveys with smartphone respondents in mind is critical.
The uneasy ceasefire in eastern Ukraine, punctuated by almost daily fighting between separatists and government forces, posed a major challenge to the Pew Research Center as we set about conducting a new public opinion survey in that country this past spring.

In early 2014, Pew Research Center set out to build a probability-based panel – the American Trends Panel – to supplement our traditional method of data collection in the U.S. – the random digit dial (RDD) telephone survey. Here's how we built and managed the panel, and what we learned from it in 2014.
Pew Research Center methodologists examine the efficacy of intensive data collection with a probability-based panel and the differences in participation and responses when using a smartphone app as opposed to a web browser for a study of smartphone use.
