Information on the number of households accepted by local housing authorities as owed a main homelessness duty is published in the first supplementary table of the Department's quarterly statistical release on statutory homelessness. This is available in both the Library of the House and via the CLG website:
http://www.communities.gov.uk/publications/corporate/statistics/homelessnessq42009
The information is collected and published at local authority level. Lancashire comprises the following local housing authorities: Burnley, Chorley, Fylde, Hyndburn, Lancaster, Pendle, Preston, Ribble Valley, Rossendale, South Ribble, West Lancashire and Wyre. The information is not collected at constituency level.
Information is also collected and reported on the number of people who sleep rough—that is, those who are literally roofless on a single night. Local authority data and count guidance can be found on the CLG website:
