Key Facts about: Inland Water Quality and Use
Number of properties at risk of flooding, 2005
England and Wales

In England and Wales an estimated 2.3million properties (9 per cent of all properties) lie in areas at risk of flooding. Of these, nearly 600,000 are in areas where the risk of flooding is greater than a 1 in 75 chance in any year.
Risks are the likelihood of flooding occurring given existing flood defences and do not reflect the extent to which flooding may be serious enough to cause damage.
This indicator is under development. Its reporting and assessment will be refined on the establishment of wider flood management measures currently in preparation.
