The Pew Research Center is a non-profit American think-tank that conducts public opinion polls, demographic studies, and social science research. They carry out interesting research on a number of social issues, so much so that they’re frequently cited in the media.
It was founded in 2004 and is primarily funded by the Pew Charitable Trusts. The center isn’t part of a university and doesn’t publish research in academic journals. It does, however, make its research available to the public by publishing their work in reports and online databases.
The Pew Research Center is an excellent source of data on public opinion. Although it is considered a non-peer-reviewed source, it has a good track record for reliability and accuracy. It is also considered a highly reputable source given their impressive track-record over the years. According to JAMA’s peer review scale, the Pew Research Center would be considered a Level 3 source, which means that it has not been peer reviewed but is of high quality and is generally reliable.
Regardless of their track-record, when using Pew data, it’s always a good idea to cite the source of the data and indicate that it is from the Pew Research Center.
I hope this answers your question.
