This chapter summarizes the current state of the literature relating to each of the disaster phases across a wide range of variables, including sociocultural factors and environment and community resources. Social networks among racial/ethnic minority cultures can be a significant protective factor against adverse mental health consequences, and the emphasis on social networks among many racial/ethnic minority cultures appears to also influence evacuation efforts. Differences in risk perception between minority and majority populations contribute to differences in disaster exposure. A variety of cultural beliefs appear to affect individuals in pre- and peridisaster phases. Several factors have an impact on marginalized populations' postdisaster mental health outcomes. Environmental and community resources suggest that limited or lack of resources appears to significantly impact disaster-response in marginalized populations. The chapter further discusses the implications for research, disaster-response efforts, and practice.
