Local Authority District (April 2021) to LAU1 to ITL3 to ITL2 to ITL1 (January 2021) Lookup in the UK

A lookup between local authority districts (LAD) as at 1st April 2021, LAU1 and International Territorial Levels (ITL level 3, ITL level 2 and ITL level 1 areas as at 1 January 2021 in the United Kingdom. (File size - 168KB) Field Names - LAD21CD, LAD21NM, LAU121CD, LAU121NM, ITL321CD, ITL321NM, ITL221CD, ITL221NM, ITL121CD, ITL121NM, FID Field Types - Text, Text, Text, Text, Text, Text, Text, Text, Text, Text Field Lengths - 9, 36, 9, 36, 5, 70, 4, 48, 3, 24 File includes changes to 7 ITL3 codes in Northern Ireland and LAD boundary changes in England 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. Lookups between NUTS and ITL geographies will be maintained and published until 2023.本数据集为2021年4月1日生效的地方当局辖区（Local Authority Districts, LAD）、LAU1与2021年1月1日生效的英国国际领土层级（International Territorial Levels, ITL）3级、2级、1级区域之间的对应查找表。（文件大小：168KB） 字段名称依次为：LAD21CD、LAD21NM、LAU121CD、LAU121NM、ITL321CD、ITL321NM、ITL221CD、ITL221NM、ITL121CD、ITL121NM、FID 字段类型均为文本型 字段长度分别为：9、36、9、36、5、70、4、48、3、24 本数据集包含北爱尔兰地区7个ITL3编码的变更记录，以及英格兰地区的LAD辖区边界变更情况。 为将英国管理的领土层级分类与欧盟前身分类相区分，英国维护的该分类体系将被称为英国国际领土层级（UK International Territorial Levels, UK ITLs）。我们致力于使ITL体系符合国际标准，以实现跨时间与跨区域的可比性，并将持续追踪全球标准动态，确保我们遵循并助力世界级统计体系的发展。 为确保英国官方统计与国际标准持续保持一致，ITL体系将以现有NUTS（Nomenclature of Territorial Units for Statistics）体系为参照建立，并采用与NUTS体系修订相近的更新周期，即每3年对ITL体系进行一次修订。将针对ITL地理区域编制新的官方GSS（Government Statistical Service）编码，该编码将与现有NUTS编码保持对齐。 鼓励统计用户自2021年1月1日起使用ITL地理区域体系替代NUTS体系。NUTS与ITL地理区域的对应查找表将持续维护并发布至2023年。
