September 2023 marked the most dramatic single-month shift in violent crime for Cottenham, a built-up area within South Cambridgeshire. The rate of violence and sexual offences fell by 46.2% compared to August, driven by a reduction from 13 to 7 incidents. This decline, coupled with an overall crime rate of 3.2 per 1,000 residents—60% below the UK average of 8.0—reflects a broader trend of low-level crime in this rural-adjacent community. The top three crime types accounted for 63.6% of the total: violence and sexual offences (31.8%), anti-social behaviour (18.2%), and public order offences (13.6%). Seasonal factors likely played a role, as September coincides with the start of the academic year, potentially increasing community vigilance and reducing opportunities for antisocial activity. While the area’s crime profile remains significantly safer than the UK average, the rise in drugs-related incidents (from 0 to 1) and bicycle theft (from 0 to 1) suggests new challenges emerging in a region with growing commuter traffic and student populations. These shifts, though minor in scale, warrant attention to local policing priorities and community engagement strategies.
