Research has found that many individuals who believe they have experienced discrimination do not report the incident to a relevant authority figure. Much of this research has focused on gender- and race-based discrimination, with relatively little research examining religion-based discrimination. Using data from a representative sample of US adults, this research note examines the rate of reporting religious discrimination to authorities and the reasons given for non-reporting. Our analysis finds that only 13 percent of individuals perceiving religious discrimination report the experience to a relevant authority figure. The most common reason for non-reporting is a belief that nothing could be done, although the reasons given for non-reporting depend in part on the specific context or type of discrimination experienced. Moreover, relative to Christians, Muslims are significantly more likely to attribute their non-reporting to a belief that nothing could be done and a fear of personal risks.
