Each mark is a postcode's centre point as ONS gives it, not a building. Press one to see its postcode and open its page. A dashed outline shows where 5 or more lie within 160 metres of each other. It is not a boundary, and no boundary is drawn. Where marks overlap, the one first in the key is drawn; the counts include every postcode.

Is SO31 at risk of flooding?

62 of the 1,188 postcodes in SO31 have a home or business in an area at risk of flooding from rivers or the sea, the Environment Agency says. At those, it puts 359 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 62 of 1,188 postcodes High: 329Medium: 30Low: 72Very low: 45

High: 3.3% or more a year (1 in 30). Medium: 1% to 3.3% a year. Low: 0.1% to 1% a year. Very low: under 0.1% a year (1 in 1,000). Each band is the chance of flooding in any one year.

Homes and businesses in an area at risk of flooding from rivers or the sea, as the Environment Agency counts them, added up over the postcodes. It is for the land, not each building, and leaves out surface water, groundwater and sewers. Each postcode page has its own figures and its flood warning areas.
