The traditional mortality mapping technique, which is based on administrative areas, suffers from the problem of instability and has difficulty in identifying spatial patterns and trends of potential interest. In this paper, the authors apply the trend surface analytic technique to model mortality rates and then use the 'Geographical Information System' (GIS) to draw maps. Data of female breast cancer mortality in the 346 administrative areas in Taiwan from 1982 to 1991 were used as an example. As compared to the traditional method, it is found that the trend surface analytic technique stabilizes mortality rates especially in areas with small populations, such as in the mountainous areas. Moreover, the technique, with the building of the 1st to the 5th order models, can provide a dynamic exhibition of patterns and trends which leads to clues about clustering and diffusion process in the mortality. The study finds higher breast cancer mortality to be clustered in several main metropolitan areas including Taipei City/County, Taichung City/County, Tainan City and Kaohsiung City. The southwestern coastal areas and the mountainous areas reveal lower mortality. It is hoped that the trend surface analysis becomes a standard public-health tool in the days to come. |
