Importance of Disaggregated Asian American Data

, by Jacqueline B. Vo (REB) and Jaimie Z. Shing (IIB)

Asian Americans are the fastest growing racial group in the United States, making up 6 percent of the population. Asian Americans are vastly diverse in ethnicity (shared cultural characteristics, such as country of origin), language, immigration patterns, cultural beliefs, English proficiency, health outcomes, and socioeconomic status.1 Disaggregated ethnicity data by country of origin (e.g., Chinese, Vietnamese, Cambodian, Asian Indian, Filipino) demonstrate inequities in income (see figure below) and in cancer risk. 2, 3

For example, cervical cancer incidence appears lower when aggregated for all Asian Americans, compared to non-Hispanic White Americans; however, when disaggregated by ethnicity, we observe that rates are much higher in Vietnamese and Cambodian but lower in Chinese and Asian Indian women.3

Research Recommendations:

  • Rigorously collect data on Asian American ethnicity (country of origin), providing the opportunity to study outcomes stratified by disaggregated ethnicity (e.g., Chinese, Vietnamese, Cambodian, Asian Indian, Filipino).
  • Use a reference group other than non-Hispanic White, as appropriate (e.g., Asian American cancer survivors compared to Asian Americans in the general population).
  • Actively engage community partners to better understand the real-life experiences and cultural and historical context among different Asian American ethnic groups.
