The age-standardized annual mortality rates for 1969/72 are analyzed for each of 183 districts which have been characterized socio-economically and demographically on the basis of the 1970 census. Discriminant analysis for several malignant tumours shows increased mortality in regions of greater population density (lung cancer) and, independently of this finding, in regions with a higher proportion of persons working in the "tertiary sector" (other malignant tumours).
根据1970年人口普查对183个地区进行社会经济和人口特征分析,计算了这些地区1969/72年的年龄标准化年死亡率。对几种恶性肿瘤的判别分析表明,在人口密度较大的地区(肺癌)死亡率有所上升,且与此发现无关的是,在从事“第三产业”人员比例较高的地区(其他恶性肿瘤)死亡率也有所上升。
