Final answer:
The majority category in the DEOCS report includes respondents who are part of the largest ethnic or demographic group identified within the surveyed population, often based on U.S. Census Bureau and OMB guidelines.
Step-by-step explanation:
For the demographic display of data in the DEOCS report, respondents included in the majority category are those who represent the largest ethnic or demographic group within the given population. In the U.S., majority categories are often determined by racial and national origin groups that are most prevalent in the population, as per guidelines from the U.S. Office of Management and Budget (OMB) and data collected by the U.S. Census Bureau. Typically, these are categorized as White, Black or African American, American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander. When viewing the demographics from a report such as the DEOCS, one must also be mindful of the context in which the survey was conducted, as this can influence demographic representation, as described by the Smithsonian Institute's road show example.
