These statistics show the amounts and location of land changing use in England. They provide a way of monitoring development such as changes to residential use. Among other statistics, they provide information on the percentage of new dwellings built on previously-developed land and non previously-developed land, the percentage of housing development in flood risk areas, on agricultural land and in the green belt and the density (dwellings per hectare) of new housing. These statistics were produced historically up until 2011 in a separate series. A new statistical series, starting in 2013-14,utilises a new methodology which is designed to produce more timely and robust statistics.
