Ashton-in-Makerfield is a market town in the Metropolitan Borough of Wigan, Greater Manchester, England, 4 miles (6.4 km) south of Wigan. As of the 2021 census, there was a population of 26,380.
Ordnance Survey places 36 postcodes in Ashton-in-Makerfield in the Environment Agency's rivers-and-sea flood-risk dataset (Risk of Flooding from Rivers and Sea). Each postcode is counted once, under the worst band any of its properties reaches; together they hold 236 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 19 | 93 | 38 |
| Medium | 3 | 25 | 23 |
| Low | 14 | 118 | 103 |
| Very low | 0 | 0 | 0 |
| All bands | 36 | 236 | 164 |
This dataset covers flooding from rivers and the sea only — one of five flood sources. Surface water, groundwater, sewers and reservoirs are assessed separately, so a postcode missing from it is not proof that a place cannot flood. The band describes the land around properties (allowing for defences), not any single address and not today's conditions.
