Between 1997 and 2010, the number of social rented homes fell by 420,000. Since 2010 the stock has increased by 76,000.
Figures for the dwelling stock owned by local authorities in England since 1994 are published by the Department in live table 116. Figures for dwelling stock at local authority level are not available prior to 1994, but are available at England level in live table 104.
Figures for the dwelling stock owned by private registered providers in England since 1997 are available in live table 115.
Where a local authority has undergone a Large Scale Voluntary Transfer (LSVT) authority, its stock would transfer to a private registered provider of social housing and the figure in live table 116 would reduce to zero or a small number.
