To ask the Secretary of State for Communities and Local Government what her most recent assessment is of the likely impact of net immigration on housing demand in England over the next 20 years; and what assessments have been made of this impact in each year since 1997. (142053)

The 2004 based household projections show that the biggest factor contributing to household growth is an increasing tendency for people to live alone.

Since 1997, Communities and Local Government have released three sets of household projections that included an assessment of the impact of migration on household formation.

2004 based household projections: Released March 2007

These project the formation of 223,000 additional households each year between 2004 and 2026 of which 73,000 (33 per cent.) are attributable to net migration into England.

2003 based household projections: Released March 2006

These projected the formation of 209,000 additional households each year between 2003 and 2026 of which 65,000 (31 per cent.) were attributable to net migration into England.

1996 based household projections: Released October 1999

These projected the formation of 150,000 additional households each year between 2001 and 2021 of which 38,000 (26 per cent.) were attributable to net migration into England.
