Waiting lists, overcrowding and homelessness are indicators of housing need and the department does not produce estimates of the shortfall in housing supply relative to need.
However, CLG has commissioned a housing need analytical model from Heriot-Watt University which will improve our understanding of the impact of housing supply on housing need going forward. It is hoped this will be available to the department by the end of the year.
The latest estimate is published in Housing Statistics, Live Table 813, Number of Children in Poor Housing (DSO 2.9), which can be downloaded from the CLG website at http://www. communities.gov.uk/documents/housing/xls/table813.xls. This estimate is based on data from the Survey of English Housing.
Overcrowding is defined according to the bedroom standard.
Forecasts for 2010 and 2011 are not available.
