Is Rosetta safe? What police records show

In the 12 months to August 2026, police recorded crimes and anti-social behaviour in Rosetta at a rate of 57.5 per 1,000 people.

That compares with 128.5 per 1,000 people across Belfast.

Across Northern Ireland as a whole, the recorded crime rate was 70.2 per 1,000 people.

In August 2026 alone, 23 cases of crime and anti-social behaviour were recorded in Rosetta.

In the 12 months to August 2026, the most common types were anti-social behaviour (106), violence and sexual offences (78) and other crime (38).

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.
