## How IP4 compares

Each postcode district against every other postcode district the measure covers.

| Measure | IP4 | Rank | Compared with |
| --- | --- | --- | --- |
| Median sale price | £275,000 | 10th cheapest | 33 postcode districts, IP · 2025 |
| Population | 38,380 | 3rd most populated | 33 postcode districts, IP · 2021 |
| People in radon Affected Area squares | 83% | 5th most people in radon Affected Areas | 33 postcode districts, IP · 2022 |

## Is IP4 safe? What police records show

In the 12 months to August 2026, police recorded crimes and anti-social behaviour in IP4 at a rate of 70.0 per 1,000 people.
That compares with 59.5 per 1,000 people across the IP postcode area.
In August 2026 alone, 208 cases of crime and anti-social behaviour were recorded in IP4.
In the 12 months to August 2026, the most common types were violence and sexual offences (1,215), other crime (528) and criminal damage and arson (262).
A year earlier, the recorded crime rate in IP4 was 70.9 per 1,000 people.
Worked out by Open Index from police.uk crime records and ONS and NISRA population estimates.
Rates are per resident, so places that many people work in or visit, such as Westminster, the City of London and other city centres, have far higher rates than their residents alone would suggest.
