In the United States, national health status data pertaining to Asian and Pacific Islander (API) Americans are rarely disaggregated. By aggregating API data, however, the poor health status of some API groups is often masked by the favorable health status of others. The purpose of this paper is two-fold: (1) to compare mortality rates of the five major ethnic groups in Hawaii (Caucasians, Chinese, Filipinos, Japanese, and Hawaiians) and (2) to explore methodological issues related to comparative studies of API health indicators. Standardized and age-specific mortality rates and 95 per cent confidence intervals for major causes of death were estimated for 1990 based on Hawaii vital records and population data. In general, death rates were highest for Hawaiians and lowest for Japanese and Chinese, illustrating the importance of API data disaggregation and suggesting that special attention be paid to improving the health of Hawaiians. Methodologically, the study demonstrated that, while some compromises in analysis are required, legitimate comparisons across API groups can be made if data sets are available.
