School safety could be a meaningful cause of educational opportunity gaps if racially minoritized and historically marginalized students are more likely to feel unsafe in school than their White peers. Feeling unsafe can be a product of attending dangerous schools and discrimination within school. This study explores the extent to which high school students from disaggregated Asian American Pacific Islander and Hispanic/Latine ethnoracial identities feel more or less safe at school than White students and potential explanations for differences in feelings of safety. We do so through decomposition using two nationally representative data sets of high school students who were in 10th grade in 2002 and 9th grade in 2009. We find Southeast Asian and Puerto Rican students in both years felt less safe than White students, with Puerto Rican students being over twice as likely to feel unsafe compared to White students. Differences in feelings of safety were often explained by school, particularly for Filipino students, as well as language spoken at home, student reports of racial/ethnic fighting at school, and some indicators of school connectedness. Implications for future research disaggregating data by ethnoracial identity are discussed.
