Data obtained from death certificates are used to establish the frequency of diseases for vital statistics. In Morgan County, Georgia, 5,787 death certificates registered between 1927 and 1979 were examined for this study. Data referable to age, sex, race, and the cause of death were recorded, with primary emphasis on cancer. The cause of death in these certificates was based primarily on clinical diagnoses. Some certificates cited neoplasms in which the site of origin was not given, and in others the type of neoplasm was difficult to correctly code. In some, a tumor was recorded but was not coded. The format of these certificates was changed by the state several times during this period, apparently to improve their credibility. Review of these registered death certificates, used for vital statistics in both Georgia and Washington, indicates that the data would contribute no scientific information on the frequency of cancer.
从死亡证明中获取的数据用于确定疾病发生频率以进行人口动态统计。在佐治亚州摩根县，本研究对1927年至1979年间登记的5787份死亡证明进行了检查。记录了与年龄、性别、种族和死因相关的数据，主要重点是癌症。这些证明中的死因主要基于临床诊断。一些证明提及了未给出起源部位的肿瘤，而在其他证明中肿瘤类型难以正确编码。在一些证明中，记录了肿瘤但未进行编码。在此期间，该州多次更改这些证明的格式，显然是为了提高其可信度。对这些用于佐治亚州和华盛顿州人口动态统计的已登记死亡证明的审查表明，这些数据不会提供有关癌症发生频率的科学信息。
