The codes consist of a simple alphanumeric structure; the first three characters (ANN) represent the area entity (i.e. type; or category of geography) and the following six characters (NNNNNN) represent the specific area instance. The CHD provides multiple functionality including details of codes, relationships, hierarchies and archived data. The CHD can be used in conjunction with the Register of Geographic Codes (RGC) that summarises the range of area instances within each geographic entity. The GSS Coding and Naming policy for some statistical geographies was implemented on 1 January 2011. From this date, where new codes have been allocated they should be used in all exchanges of statistics and published outputs that normally include codes.

本压缩包包含截至2017年12月的英国代码历史数据库（Code History Database, CHD）。如需获取该压缩包，请点击"下载"按钮。 代码历史数据库（CHD）收录了2009年1月1日起已分配的政府统计服务（Government Statistical Service, GSS）九位字符代码，涵盖现行及新增统计地理区域。该代码采用简洁的字母数字结构：前三位字符（ANN）代表区域实体，即地理类型或类别，后六位字符（NNNNNN）代表具体区域实例。CHD具备多项核心功能，可提供代码详情、关联关系、层级结构及存档数据等内容。CHD可与地理代码登记册（Register of Geographic Codes, RGC）配合使用，后者汇总了各地理实体下的全部区域实例范围。部分统计地理区域的GSS编码与命名政策于2011年1月1日起正式实施，自此之后分配的新代码，需在所有统计数据交换及常规包含代码的发布成果中使用。如需了解该产品的更多详情，请参阅产品压缩包内的用户指南与版本说明。 ### 更新的地理区域 · 新增郡选举分区（County Electoral Divisions, E58）实体 · 更新英格兰选举分区（Electoral Wards in England, E05）、英格兰临床委托组（Clinical Commissioning Groups, E38，含名称变更）及英格兰废物管理当局（Waste Authorities in England, E50）的相关信息 · 所有地理区划已同步更新至2017年12月31日版本 · 修订法定文书（Statutory Instrument, SI）详情、名称变更及信息表 ### 数据库变更 · 已针对2017年12月版本更新表单设计 · 注意：Equivalents.csv及数据库中的"Combined"字段已移除，该字段曾用于质量保证（Quality Assurance, QA）。（2018年3月2日） · 已将部分临床委托组添加至等效表（Equivalents table）。（2018年3月9日）
