摘要

推估人口暴露量是災害防救與風險管理的重要過程之一，但因為隱私權因素，人口資料多以行政單元進行發布與統計，易引起面積可調整單元問題與空間趨勢的扭曲。故內政部統計處建立一個比行政單元更小的空間單元、空間單元均勻性高且邊界穩定的單元系統－統計區分類系統。本文應用較小空間單元之人口統計，有效且正確推估洪災潛勢區內的影響的人口暴露量，以洪災潛勢事件為例，應用洪災潛勢圖推估淹水潛勢區內的影響人數，闡述統計區分類系統之效益。

Assessing exposure of population in potential hazard area is vital process in disaster prevent ion and risk management. Population data always were aggregated into administrative district and published for individual private. However, it causes the modifiable areal unit problem (MAUP) and destroy spatial pattern for aggregating data. To solve this problem, Department of Statistics, Ministry of the Interior constructed census demography system which has multi-scale unit, space homogenous and steady boundary of characteristic. The purpose of this research is using multi-unit to estimate population exposure and using flood event to estimate population exposure for explaining the utility of census demography system.
