Introduction to Gwynedd's crime statistics
This crime profile provides a detailed view of crime and safety around Gwynedd up to April 2026, the most recent data release available. The crime figures and statistics have been calculated across each of Gwynedd's 9,770 postcodes using three area sizes for comparison:
- Within a Five-Minute Walk
- Within a Ten-Minute Walk
- Within a Fifteen-Minute Walk
Individual crime risk scores and index figures are for the 12-month period ending April 2026 unless otherwise stated.
Crime Risk Scores
Gwynedd • 12 Months Ending April 2026
The typical five-minute walk within Gwynedd has a crime risk score of 641. This is based on analysis of 9,770 nearby areas within Gwynedd, with "most" referring to roughly two thirds of the nearby locations.
Crime risk scores are on a scale of 1 to 1,000 and consider the severity of the crimes involved, as determined by sentencing guidelines. A score of 1 represents the lowest risk, and 1,000 the highest risk. This approach ensures that - unlike overall crime rate figures - bicycle theft is not given the same importance in Gwynedd's risk scores as, for example, robbery, or violence & sexual offences.
Within a five-minute walk of the typical location in Gwynedd, crime risk scores are typically around 641, while in Wales they are average 606.
Areas within a ten-minute walk typically see crime risk scores of 635 (634 for Wales), and scores within a fifteen-minute walk are most often around 646 (Wales 654).
Trends in Crime Risk
Gwynedd
Calculated via Seasonal and Trend decomposition using Loess, the Seasonality Adjusted line represents the original data with seasonality subtracted, and the Trend line has been plotted unadjusted. Overall trend direction has been identified using the Mann-Kendall trend test, and rate calculated from the slope of the best-fit line identified from linear regression.
The 10-year trend indicates an increase of 6% in Gwynedd's crime risk score. This is potentially a strong signal of how the crime risk is evolving. Cross-referencing with major cultural events and Covid's impact during this time is advised.
The five-year trend may be static; no significant trend was identified in Gwynedd's crime risk scores during this timeframe.
Over the last year, Gwynedd's crime risk score has shown an upward trend of approximately 3.2%, indicating that the risk profile is going up. This is an extremely short time period for crime trend analysis, and caution should be exercised when interpreting this figure.

The Gwynedd Streets With The Highest Crime Counts
Each police crime report that CrimeRate receives has a street name automatically assigned to it by the police data team, and this table uses the coordinates to count crimes, rather than the street name alone. That way, if Gwynedd has multiple identical street names - which is not unusual - they will be treated separately by CrimeRate's systems.
