## Is N4 safe? What police records show

In the 12 months to August 2026, police recorded crimes and anti-social behaviour in N4 at a rate of 172.6 per 1,000 people.
That compares with 130.0 per 1,000 people across the N postcode area.
In August 2026 alone, 848 cases of crime and anti-social behaviour were recorded in N4.
In the 12 months to August 2026, the most common types were anti-social behaviour (2,372), violence and sexual offences (2,060) and other crime (1,529).
A year earlier, the recorded crime rate in N4 was 183.0 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.
