## Is CO10 safe? What police records show

In the 12 months to August 2026, police recorded crimes and anti-social behaviour in CO10 at a rate of 51.8 per 1,000 people.
That compares with 83.5 per 1,000 people across the CO postcode area.
In August 2026 alone, 277 cases of crime and anti-social behaviour were recorded in CO10.
In the 12 months to August 2026, the most common types were violence and sexual offences (1,321), other crime (467) and criminal damage and arson (291).
A year earlier, the recorded crime rate in CO10 was 52.0 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.
