Data-Gouv-FR/statistiques-dvf
收藏资源简介:
该数据集包含法国房地产交易(DVF)的统计信息,可在网站explore.data.gouv.fr/immobilier上可视化。文件包含销售数量、每平方米价格的平均值和中位数。数据集分为两个子集:总统计DVF(基于10个半年的可用数据,按地理尺度统计)和月度统计DVF(按地理尺度和月份统计)。数据处理基于法国房地产交易数据,通过代码生成不同尺度和时间段的统计指标。统计指标包括:交易数量、每平方米价格的平均值和中位数、销售价格分布(按价格区间)。这些指标针对以下房产类型计算:房屋、公寓、房屋+公寓、商业场所。地理尺度包括:国家、部门、EPCI(公共机构间合作机构)、市镇、地籍分区。数据源包含多种交易类型,但统计中仅保留销售、未来完工状态销售和拍卖。此外,为简化处理,仅保留涉及单一房产(不含附属物)的交易。每平方米价格通过交易价值除以建筑表面积计算,排除无法计算或价格超过10万欧元(任意阈值)的交易。统计中未应用其他异常值限制,以保持数据原始性,但网站显示中位数以减少异常值对颜色尺度的影响。
This dataset provides statistical information on French real estate transactions (DVF), which is available for visualization on the website explore.data.gouv.fr/immobilier. It includes metrics such as the number of transactions, as well as the mean and median price per square meter. The dataset is split into two subsets: the aggregate statistical DVF (based on 10 semi-annual batches of available data, aggregated by geographic scale) and the monthly statistical DVF (aggregated by both geographic scale and month). Data processing is conducted using French real estate transaction data, with code generating statistical indicators across varying geographic scales and time periods. The covered statistical indicators include: transaction count, mean and median price per square meter, and sales price distribution stratified by price brackets. These indicators are computed for four property categories: single-family houses, apartments, combined houses and apartments, and commercial properties. Geographic aggregation scales include: national level, French departments, EPCI (Public Intercommunal Cooperation Institutions), communes, and cadastral zones. The original data source encompasses multiple transaction types, yet only sales, off-plan (future completion) sales, and auction sales are retained for statistical analysis. Additionally, to streamline processing, only transactions involving a single standalone property (excluding any associated appurtenances) are included. Price per square meter is calculated as the ratio of transaction value to the building's surface area. Transactions that cannot be properly calculated or those with a price exceeding 100,000 euros (an arbitrary threshold) are excluded from the calculations. No additional outlier filtering is applied to preserve the original integrity of the dataset, though the median price is displayed on the website to mitigate the impact of outliers on the color scale used for data visualization.
