Abstract

This research examined relationships between Scientifically Estimated Environmental Risks (SEERs) of floods, hurricanes and hazardous material releases, and household characteristics. This research showed that there were no statistically significant relationships between most of the demographic characteristics (age, household size, tenure at the present home) and SEERs of the two natural hazards (a flood and a hurricane). These results support Drabek's findings (1986) that people tend to underestimate or ignore natural hazards in selecting their residence regardless of age, household size, and house tenure. Educational attainment and yearly household income were positively correlated with hurricane risk, but not with flood risk. By contrast, SEER of hazardous materials was correlated with all demographic characteristics mentioned above. This result may show that those who are relatively poorer and have lower educational level tend to be limited to living in communities more vulnerable to human-made risk.

이 연구는 홍수, 허리케인, 위험물질 누출에 대한 과학적으로 측정된 환경위험지수와 가계의 특성간의 상관관계를 조사하였다. 이 연구는 인구적 특성(연령, 가족 수, 결혼 상태, 거주 기간)과 두 가지 자연재해(홍수와 허리케인)의 위험지수 사이에는 통계적으로 유의미한 관계가 없음을 보여주었다. 이 결과는 Drabek의 연구 결과를 지지하는 바, 사람들은 그들의 나이, 성별, 가족수, 결혼 상태, 거주기간과 관련 없이 그들의 주거를 선택하는데 자연재해의 가능성을 과소평가하거나 무시하는 경향이 있음을 보여주고 있다. 대조적으로, 위험물질 누출에 대한 환경위험지수는 위에 열거한 인구적 특성과 통계적으로 유의미한 상관관계를 보여주었다. 이는 가난하고 학력 수준이 낮은 사람들이 인적 재난에 더 노출된 지역사회에 사는 경향이 있음을 보여주고 있다.
