A lookup between local authority districts (LAD) as at 1st April 2025, LAU1 and International Territorial Levels (ITL level 3, ITL level 2 and ITL level 1 areas as at 1st January 2025 in the United Kingdom. (File size - 120KB) Field Names - LAD25CD, LAD25NM, LAU125CD, LAU125NM, ITL325CD, ITL325NM, ITL225CD, ITL225NM, ITL125CD, ITL125NM Field Types - Text, Text, Text, Text, Text, Text, Text, Text, Text, Text Field Lengths - 9, 36, 9, 36, 5, 52, 4, 46, 3, 24 Boundary change between Barnsley and Sheffield - new LAD codes: E08000038 - Barnsley, E08000039 - Sheffield To distinguish the UK classification from its EU predecessor, the UK-managed classification will be referred to as UK International Territorial Levels (ITLs). We are committed to ITLs aligning with international standards, enabling comparability both over time and internationally, and we will actively monitor global standards to ensure we are following and contributing to the development of world-class statistics. To ensure continued alignment between UK official statistics and international standards, the ITLs will be established as a mirror to the pre-existing NUTS system and will follow a similar timetable to the review of the NUTS system, meaning ITLs will be reviewed every 3 years. New official GSS codes will be developed for the ITL geography aligned with existing NUTS codes. Statistical users are encouraged to adopt the ITL geography from 1 January 2021 as a replacement to NUTS.本数据集为截至2025年4月1日的地方当局辖区（Local Authority Districts, LAD）、LAU1与截至2025年1月1日英国境内的国际区域层级（International Territorial Levels，含ITL 3级、ITL 2级及ITL 1级区域）的对应对照表。（文件大小：120KB） 字段名称依次为：LAD25CD、LAD25NM、LAU125CD、LAU125NM、ITL325CD、ITL325NM、ITL225CD、ITL225NM、ITL125CD、ITL125NM 所有字段类型均为文本（Text） 各字段长度依次为：9、36、9、36、5、52、4、46、3、24 巴恩斯利（Barnsley）与谢菲尔德（Sheffield）的辖区边界已完成调整，新增LAD代码如下：E08000038 - 巴恩斯利，E08000039 - 谢菲尔德 为区分英国官方管辖的分类体系与其欧盟前身，该体系将被称为英国国际区域层级（UK International Territorial Levels, UK-ITLs）。我方致力于确保ITL体系契合国际标准，以实现跨时间与跨地域的统计可比性；同时将持续监控全球标准动态，确保遵循并助力世界级统计体系的发展完善。为保障英国官方统计数据与国际标准持续对齐，ITL体系将作为现有NUTS体系的镜像版本设立，并沿用与NUTS体系评审一致的周期，即每3年对ITL体系开展一次全面评审。将针对与现有NUTS代码匹配的ITL地理分区，开发全新的官方政府统计服务（Government Statistical Service, GSS）代码。鼓励统计使用者自2021年1月1日起采用ITL地理分区，以替代原有的NUTS体系。
