Permanent dwellings started, England, District By Tenure - Rolling 4 quarter total

This data set contains rolling four quarter totals (England only) on house building starts. From 2011/12 imputed data is included. Imputed data should not be seen as an estimate for the individual authority but is given on an authority basis to allow custom totals to be constructed.

England total figures include estimates for missing data returns from independent Approved Inspectors and Local Authorities, so the sum of district values may be slightly less than the England totals.

House building starts - A dwelling is counted as started on the date work begins on the laying of the foundation, including 'slabbing' for houses that require it, but not including site preparation. Thus when foundation work commences on a pair of semi-detached houses two houses are counted as started, and when work begins on a block of flats all the dwellings in that block are counted as started. The starts of houses in building schemes are usually phased over a period of weeks or even, in very large schemes, months.

The data are derived from live table 253a (quarterly figures), and rolling totals for England are calculated and published in Tables 2a and 2b of the house building statistics [release](https://www.gov.uk/government/collections/house-building-statistics).

本数据集包含英格兰地区房屋建设开工的四季度滚动总和（仅限英格兰）。自2011/12年起，包含了推算数据。推算数据不应被视为单个行政区的估计值，而是以行政区为单位提供，以便构建定制总和。
英格兰的总数包括了独立批准检查员和地方当局缺失数据返回的估计值，因此区划数值的总和可能略低于英格兰的总数。
房屋建设开工：一套住宅在开始铺设地基的日期被计算为开始建设，包括需要的话进行楼板施工，但不包括场地准备。因此，当一对半独立式住宅的地基工作开始时，计算为两套住宅开始建设，而当一栋公寓楼的建设工作开始时，该楼内的所有住宅都被计算为开始建设。建设项目的房屋开工通常在数周甚至在一些非常大的项目中，可能需要数月的时间分阶段进行。
数据来源于实时表格253a（季度数据），英格兰的滚动总和计算并发布在房屋建设统计数据[发布](https://www.gov.uk/government/collections/house-building-statistics)的表格2a和2b中。
