Low-use properties maps and LSOA data files

Maps and data from our low-use properties dataset, includes maps at national and small area levels within all returning (205) local authorities across the UK. Data for Scotland is complete, no data available for Northern Ireland.This repository contains the digital outputs of the Project 'Low-use homes in rural and coastal areas of the UK: Geography impact and responses'.The report and executive summary are available from the White Rose Repository<b>Contents</b>This repository contains the following:- Map folders- Dataset files## Maps- maps_absolute: Maps for each local authority for which the project had data, coloured by the low-use decile of each LSOA of the local authority relative to the entire dataset- maps_relative: Maps for each local authority for which the project had data, coloured by the low-use decile of each LSOA of the local authority relative to the local authority.- maps_country: Maps that the cover each of the countries in Great Britain i.e. England, Scotland, Wales. Their are two sets of maps, maps coloured by decile, and maps coloured by whether the price difference between low-use homes and occupied homes is statistically significant.### Explanation on the difference between the relative and absolute decilesWhen looking at the absolute and relative maps of the local authority of Dorset, it is clear they are very different. In the absolute map Dorset has a lot of D10, whilst in the relative map there is an even spread. This is because deciles always represent 10% of the data, so the relative map has 10% of the Dorset LSOA's in each of the 10 deciles. However, Dorset has a much higher number of low-use properties than the average local authority, so the absolute map has significantly more LSOA in the 10th decile. You can see in the legend of the maps that the decile boundaries are different. The table below compares the national level deciles (absolute) with the deciles for Dorset (relative) which has more than average low-use homes, and the decile boundaries for Colchester, which has less than average low-use homes.<b>Datasets</b>- ghost_enclave_20.csv: List of LSOA with at least 20% low-use properties- ghost_enclave_25.csv List of LSOA with at least 20% low-use properties- highest_30_LUP_LADS.csv: The top 30 local authorities in terms of low-use properties- low_use_price_extremes.csv: Most extreme ratios of house price to low-use for the three Nations- low_use_price_extremes.xlsx: Most extreme ratios of house price to low-use for the three Nations- weighted_price_LAD.csv: The entire dataset aggregated to local authority level<br><br>

本数据集源自我们的低使用率房产数据集，涵盖英国境内全部205个已上报数据的地方当局（local authority）的国家级与小区域级地图与数据。苏格兰地区数据完整，北爱尔兰暂无可用数据。本仓库包含项目《英国乡村与沿海地区低使用率住宅：地理影响与应对策略》的数字化产出成果。该项目的报告与执行摘要可从White Rose Repository获取。

## 地图
- maps_absolute：针对本项目获取了数据的每个地方当局制作的地图，按该地方当局下属每个低层超级输出区域（Lower Layer Super Output Area，LSOA）相对于全数据集的低使用率十分位数进行着色
- maps_relative：针对本项目获取了数据的每个地方当局制作的地图，按该地方当局下属每个LSOA相对于该地方当局自身的低使用率十分位数进行着色
- maps_country：覆盖大不列颠各构成国（即英格兰、苏格兰、威尔士）的地图。此类地图包含两类：按十分位数着色的地图，以及按低使用率住宅与已入住住宅间的房价差值是否具有统计学显著性着色的地图

### 相对与绝对十分位数差异说明
以多塞特（Dorset）地方当局的绝对与相对十分位数地图为例，二者差异显著：在绝对分位数地图中，多塞特存在大量D10（第十十分位数）区域；而在相对分位数地图中，各十分位数分布均匀。这是因为十分位数始终代表10%的数据集样本，因此相对分位数地图中，多塞特的每个LSOA均均匀分布于10个分位数区间内。但多塞特的低使用率房产数量远高于地方当局平均水平，因此绝对分位数地图中，处于第十分位数的LSOA数量显著更多。从地图图例中可看到二者的分位数边界并不相同。下表对比了国家级绝对分位数边界、低使用率房产高于平均水平的多塞特的相对分位数边界，以及低使用率房产低于平均水平的科尔切斯特（Colchester）的相对分位数边界。
