Crime severity: 0.6× the Merthyr Tydfil average (0.7× the England and Wales average). 52 recorded crimes per 1,000 residents a year.

"Violence and sexual offences" is 73% of the harm here. It is a broad police category: most of these crimes are assaults without injury, harassment and threats, often indoors between people who know each other, and only a small part are sexual or serious violent offences. Police data does not say which, so each one is weighted at the England and Wales average for the category, which can overstate a quiet residential area.
Anti-social behaviour: 13 incidents per 1,000 residents a year, not scored. Not a crime, so it is not part of the Safety score.
