本文件包含了伯明翰地区2021年人口普查地理信息中下层超级输出区域（LSOAs）的数字矢量边界。可用的边界包括：泛化裁剪（BGC）- 将其泛化至20米并裁剪至海岸线（平均高潮位标记），相较于BFE边界更为泛化。下层超级输出区域（LSOAs）由多个输出区域（OAs）组成，通常为四个或五个。它们包含400至1200户家庭，通常居民人口介于1000至3000人之间。利用2021年人口普查数据，由于自2011年以来人口和家庭的变动，对2011年的LSOAs进行了某些调整。通过合并或分割2011年的LSOAs创建新的2021年LSOAs，以确保满足人口和家庭阈值。包含奥尔德萨纳（Ordnance Survey）和英国国家统计局（ONS）的知识产权。TopoJSON Shapefile适用于Power BI - 在“导出”选项卡下，您可以在“替代导出”部分找到一个文件。此文件采用TopoJSON格式，适用于Power BI或Mapbox等兼容的可视化工具。
