"The paper describes a problem faced by National Statistical Offices when publishing the results of decennial censuses for small geographical areas. If they publish statistical tables for two or more sets of areas, users can compare the tables and produce new statistics for the areas formed by differencing, which may have populations below confidentiality thresholds. To investigate the problem, the authors construct a software system and carry out a series of experiments using a large synthetic population base for Yorkshire and Humberside [in England]. The results indicate that publishing statistics for zones close in size to the primary areas is not safe unless the zones have been carefully designed. However, publishing statistics for sufficiently large areas such as 5km grid squares or postal sectors alongside enumeration districts is safe."

人口普查局是否可以发布多个小区域地理的统计数据？统计披露中的差异化问题分析

“该论文描述了国家统计局在发布小地理区域的十年一次普查结果时面临的一个问题。如果他们发布两组或更多组区域的统计表，用户可以比较这些表并为由以下人员组成的区域生成新的统计数据。差分，这可能有低于保密阈值的人口。为了调查这个问题，作者构建了一个软件系统，并使用 [英格兰] 的约克郡和亨伯赛德的大型合成人口基数进行了一系列实验。结果表明除非经过精心设计，否则与主要区域大小接近的区域是不安全的。但是，发布足够大的区域（例如 5 公里网格方格或与查点区并列的邮政部门）的统计数据是安全的。”
