Output Area (2011) to LAUs (2010) to NUTS3 to NUTS2 to NUTS1 (2006) Best Fit Lookup in EW
收藏资源简介：
<span style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", Helvetica, Arial, sans-serif; font-size:17px;'>A best-fit lookup between Output Areas (OA) to Nomenclature of Territorial Units for Statistics (NUTS) and Local Administrative Units (LAU) as at 31 December 2011 in England and Wales. The NUTS areas (Levels 1, 2 and 3) are operative as at January 2006 and the LAU areas (Levels 1 and 2) are operative as at January 2010. The methodology used to create the OA lookups is based on the distribution of 2011 Census population. A median average of each OA's household grid references, weighted by the population at each household has been used to create a population weighted centroid for each OA. This centroid has been used to allocate the OA and all its associated statistics to any higher geographies. Information on the percentage of an output areas population that falls into the higher geography has also been included in this best-fit lookup file. A ‘best-fit percentage’ indicator has been included in this lookup, to support an understanding of the actual relationship between the OA and the higher geography to which it has been best-fitted. This ‘best-fit percentage' indicator has been calculated by working out the percentage of the OA’s population that falls exactly within the output geography's boundary. This is calculated by plotting the grid references of the households into the output geography's digitised boundaries and aggregating the population that actually falls within the best-fitted geography's boundary. 100 indicates that all the OA's population actually fell within the best-fitted boundary. A value of 90 means that the OA's boundary is split across the output geography's boundary and that 90% of the OA's population actually fell within the geography the OA was best-fitted to. Only the higher geography to which the OA has been allocated will be given a percentage match.

本数据集为英格兰及威尔士地区截至2011年12月31日的输出区域（Output Areas, OA）与统计区域命名法（Nomenclature of Territorial Units for Statistics, NUTS）及地方行政单位（Local Administrative Units, LAU）之间的最优匹配查找表。其中，统计区域命名法区域（1、2、3级）的生效时间为2006年1月，地方行政单位区域（1、2级）的生效时间为2010年1月。 本匹配表的构建方法基于2011年人口普查的人口分布：以各住户的人口数为权重，对每个输出区域的住户网格坐标取中位数平均值，生成每个输出区域的人口加权质心（population weighted centroid），以此将输出区域及其关联的全部统计数据分配至更高层级的地理区域。 该最优匹配查找文件中还包含了输出区域人口落入更高层级地理区域的占比信息，同时设置了「最优匹配占比（best-fit percentage）」指标，用于辅助理解输出区域与其匹配的上级地理区域之间的实际对应关系。该指标的计算方式为：将各住户的网格坐标映射至对应输出地理区域的数字化边界中，汇总实际落在最优匹配地理区域边界内的人口，以此计算该输出区域人口中落入该地理区域的百分比。当该指标取值为100时，表示该输出区域的全部人口均落在该最优匹配边界内；若取值为90，则代表该输出区域的边界跨该输出地理区域的边界，且该输出区域90%的人口实际落入其被匹配至的地理区域。仅会为输出区域被分配至的上级地理区域赋予匹配百分比。本文件大小为26.5MB。 ### 字段名称 依次为：OA11CD、LAU210CD、LAU210NM、OA11PERCENT、LAU110CD、LAU110NM、OA11PERCENT1、NUTS306CD、NUTS306NM、OA11PERCENT2、NUTS206CD、NUTS206NM、OA11PERCENT3、NUTS106CD、NUTS106NM、OA11PERCENT4 ### 字段类型 全部为文本类型 ### 字段长度 依次为：9、10、56、3、7、28、3、5、70、3、4、48、3、3、24、3 ### 要素访问服务REST URL https://services1.arcgis.com/ESMARspQHYMw9BZ9/arcgis/rest/services/OA11_LAU2_LAU1_NUTS3_NUTS2_NUTS1_EW_LU_25dc24c61a1b47d1834184ba01094dc3/FeatureServer 如需了解更多信息及最优匹配方法的概述，请访问以下链接： https://geoportal.statistics.gov.uk/datasets/f0aac7ccbfd04cda9eb03e353c613faa/about
