Net additional dwellings data is available by London borough since the 2004/05 financial year, while total dwelling estimates start from 2001. The dataset, compiled by the Greater London Authority, combines information from local authorities and the GLA, and includes an average dwelling size figure calculated using ONS population estimates. Figures from 2002 to 2011 were revised following the 2011 census, and data from 2003 and 2004 contain imputed values.
