收藏资源简介：
<span style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; color:rgb(0, 0, 0); font-size:17px;'>This is an exact fit lookup file between Lower layer Super Output Areas as at December 2011 and Lower layer Super Output Areas as at December 2021 and Local Authority Districts as at December 2022 in England and Wales. This product has been provided with a 'change indicator' field, that define the lookup between 2011 and 2021 LSOA. This field indicates which super output areas have changed between 2011 and 2021. </span><div><font color='#000000' face='Avenir Next W01, Avenir Next W00, Avenir Next, Avenir, Helvetica Neue, sans-serif'><span style='font-size:17px;'><br /></span></font></div><div><font color='#000000' face='Avenir Next W01, Avenir Next W00, Avenir Next, Avenir, Helvetica Neue, sans-serif'><span style='font-size:17px;'>This is a version 2 of the lookup where the Change Indicator has been changed from splits to complex in less than 10 LSOAs<br /></span></font><div style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'><span style='color:rgb(0, 0, 0); font-size:17px;'><br /></span></div><div style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'><span style='color:rgb(0, 0, 0); font-size:17px;'>There are four designated categories to describe the changes, and these are as follows:</span></div><div style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'><span style='color:rgb(0, 0, 0); font-size:17px;'>U - No Change from 2011 to 2021.

This means that the 2011 LSOA has been split into two or more 2021 LSOA. There will be one record for each of the 2021 LSOA that the 2011 LSOA has been split into. This means direct comparisons can be made between estimates for the single 2011 LSOA and the estimates from the aggregated 2021 LSOA.</span></div><div style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'><span style='color:rgb(0, 0, 0); font-size:17px;'>M - Merged. 2011 LSOA have been merged with another one or more 2011 LSOA to form a single 2021 LSOA. This means direct comparisons can be made between the aggregated 2011 LSOAs’ estimates and the single 2021 LSOA’s estimates. </span></div><div style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'><span style='color:rgb(0, 0, 0); font-size:17px;'>X - The relationship between 2011 and 2021 LSOA is irregular and fragmented. This has occurred where 2011 LSOA have been redesigned because of local authority district boundary changes, or to improve their social homogeneity. These can’t be easily mapped to equivalent 2021 LSOA like the regular splits (S) and merges (M), and therefore like for like comparisons of estimates for 2011 LSOA and 2021 LSOA are not possible. </span></div><div style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'><span style='color:rgb(0, 0, 0); font-size:17px;'><br /></span></div><div style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'><span style='color:rgb(0, 0, 0); font-size:17px;'>Field Names – LSOA11CD, LSOA11NM, CHGIND, LSOA21CD, LSOA21NM, LAD22CD, LAD22NM, LAD22NMW</span></div><div style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'><span style='color:rgb(0, 0, 0); font-size:17px;'>Field Types – Text, Text, Text, Text, Text, Text, Text, Text</span></div><div style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'><span style='color:rgb(0, 0, 0); font-size:17px;'>Field Lengths – 9, 33, 1, 9, 40, 9, 35, 24</span></div></div>
本文件为英格兰与威尔士地区2011年12月版下层超级输出区（Lower layer Super Output Areas, LSOA）、2021年12月版下层超级输出区，以及2022年12月版地方当局辖区（Local Authority Districts, LAD）之间的精准匹配对照表。该对照表附带变化标识（Change Indicator）字段，用于界定2011与2021版LSOA之间的匹配关系，该字段可标识出2011至2021年间发生变更的超级输出区。 本对照表为V2版本，其中不足10个LSOA的变化标识（Change Indicator）已从拆分（Split）类型调整为复杂（Complex）类型。 本次变更共划分为四类标准场景，具体如下： U：2011至2021年无变更。此类场景下可直接对2011版与2021版LSOA开展对等对比分析。 S：拆分。即单个2011版LSOA被拆分为2个及以上2021版LSOA，原2011版LSOA每拆分出一个2021版LSOA即对应一条数据记录。此类场景下可直接对比单个2011版LSOA的统计估算值与对应聚合后的2021版LSOA统计估算值。 M：合并。即1个或多个2011版LSOA与其他1个或多个2011版LSOA合并为单个2021版LSOA。此类场景下可直接对比聚合后的2011版LSOA统计估算值与单个2021版LSOA的统计估算值。 X：匹配关系不规则且碎片化。该场景源于地方当局辖区边界调整，或为提升区域社会同质性而对2011版LSOA进行重新规划。此类变更无法像常规拆分（S）与合并（M）场景那样，便捷地匹配至对应的2021版LSOA，因此无法对2011版与2021版LSOA的统计估算值开展对等对比。 字段名称依次为：LSOA11CD、LSOA11NM、CHGIND、LSOA21CD、LSOA21NM、LAD22CD、LAD22NM、LAD22NMW 字段类型均为文本型（Text） 字段长度依次为：9、33、1、9、40、9、35、24
