The town had an estimated population of 143,418 in 2024, making it the second-largest town in the ceremonial county of Dorset.

Ordnance Survey places 169 postcodes in Poole 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 2,035 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 42 | 357 | 184 |
| Medium | 55 | 643 | 458 |
| Low | 69 | 970 | 772 |
| Very low | 3 | 65 | 53 |
| All bands | 169 | 2,035 | 1,467 |
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.
…and 69 more at-risk postcodes, listed on the district pages below.

The nearest watercourse on the river map is Little Channel (Back Water Channel) (tidal here), about 70 m from the middle of Poole's gauges. It flows into Main Channel about 1.9 km downstream.
A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on Little Channel (Back Water Channel) nearest the middle of Poole's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
