Ethnicity In the 1970s, hazard research was driven by new interest in demographic variations and focused on racial, ethnic and socioeconomic differences in disaster responses. Research shows that minorities are less involved in pre-disaster preparation and are more vulnerable to disasters. According to the 2010 Census, ethnic makeup of the City of Superior shows over 90% of the population listed their race as white and nearly 98% as born in the United States. Racial estimates for 2009-2013 indicate an increase in White, Black/African American, and Asian citizens.
