In late March 2019, the Pew Research Center published a report that examined the scientific knowledge levels among American adults. This study, based on a nationally representative survey of 4,464 adults conducted in January 2019 by Pew's American Trends Panel, probed Americans' knowledge in four scientific areas: life science, Earth and physical science, numeracy and chart reading, and scientific processes. The study found that "[t]here are striking differences in levels of science knowledge by education as well as by racial and ethnic group," noting that several factors may be tied to the latter, including "educational attainment and access to science information." In contrast, the study found roughly similar levels of scientific knowledge across political ideologies and across age groups. Readers interested in more details may read the full 28-page report online or download it as a PDF at the link above, along with the survey's topline questionnaire results and an appendix with detailed demographic breakdowns of the results. They should also check the interactive quiz to see how their own knowledge compares to the survey results. This report was written by Pew researchers Brian Kennedy and Meg Hefferon.
