Ystrad Mynach has seen a dramatic 41.7% year-on-year decline in crime, with a rate of 61.1 per 1,000 residents—33% below the UK average. While violence and sexual offences remain the most common crime type, their rate is 17% below the national average. This stark reduction, particularly in possession of weapons (-78.3% YoY), suggests effective policing or community interventions are reshaping the area's safety profile.
