The mortality and size of the extreme aged population can be studied most accurately with Medicare enrollment data from the Social Security Administration's Master Beneficiary Record after certain types of questionable records are eliminated. With the improved data base we find that mortality rates at the very old ages are higher than published rates, we are more confident of the reality of the race crossover, and we can estimate the number of centenarians more accurately. Furthermore, a large matched-records study shows close agreement on age at death between the Master Beneficiary Record and the death certificate.
在剔除某些有问题的记录后，利用社会保障管理局的主受益人记录中的医疗保险参保数据，可以最准确地研究高龄人口的死亡率和规模。基于改进后的数据库，我们发现极高龄人群的死亡率高于已公布的比率，我们对种族交叉现象的真实性更有信心，并且能够更准确地估算百岁老人的数量。此外，一项大型匹配记录研究表明，主受益人记录与死亡证明在死亡年龄方面高度一致。
