CrimeRate Insights
Looking into a specific address in Cornelly? CrimeRate Insights reports convert raw numbers into practical insight for any location, from single addresses and postcodes, up to major towns and cities.
Crime rates don’t happen by themselves; they follow people and patterns. Where crowds gather - near pubs and late-night venues, around the station, by supermarkets and forecourts - incidents naturally concentrate.
That doesn’t mean an area is "bad"; it usually means footfall is higher.
Your report explores these factors in a calm, non-judgemental way, putting the numbers in context and helping you spot what’s typical for places like this.
Crime Risk Scores
Cornelly • 12 Months Ending April 2026
The typical five-minute walk within Cornelly has a crime risk score of 720. This is based on analysis of 151 nearby areas within Cornelly, 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 Cornelly's risk scores as, for example, robbery, or violence & sexual offences.
Within a five-minute walk of the typical location in Cornelly, crime risk scores are typically around 720, while in Mid Glamorgan they are average 604.
Areas within a ten-minute walk typically see crime risk scores of 755 (672 for Mid Glamorgan), and scores within a fifteen-minute walk are most often around 756 (Mid Glamorgan 722).

Methodology & Data Sources
Cornelly Crime Report
Data Sources & Processing
Every month, CrimeRate processes crime reports from data.police.uk, the UK's official provider of open crime report data. Each crime report includes anonymised coordinates, most often "snapped" to the middle of the nearest street, or to the nearest major landmark. The reports also include the month and year the crime was reported, as well as the type of crime.
Data releases on data.police.uk happen once a month, with a two-month delay. This means that, for example, crimes reported in Cornelly during June 2026 will typically become available in August 2026. The latest release is for Apr 2026 and was released in Jun 2026. To provide current and historical crime statistics, CrimeRate processed 61,669,232 crime reports for the latest release.
Cornelly Data Points
For Cornelly, CrimeRate uses the geographic boundaries provided by The Office for National Statistics in the December 2023 release of their Parishes and Non Civil Parished Areas dataset, using the PARNCP23CD column value W04000648.
Due to the 2021 Census being conducted during a UK-wide Coronavirus lockdown, the daytime population figures released so far cannot be relied on for purposes such as comparing crime rates. Instead, CrimeRate uses Cornelly's daytime - or "workday" - population of 5,249 from the ONS 2011 Census for calculations throughout the site.
All geographic boundaries use the full resolution - extent of the realm versions where provided to avoid missing crime reports near coastlines and rivers - the banks of the Thames in particular - that would otherwise not be included when using the clipped to the coastline datasets.
Calculating Crime Rates
CrimeRate locates the UK region, county, and town/city/village locality for each crime report, and calculates the crime rate by taking the sum of all crime reports, dividing it by the locality's daytime / "workday" population, and multiplying the result by 1,000 to get the crime rate per 1,000.
Crime Risk Score Calculations
CrimeRate calculates crime counts for local, nearby, and wider areas for every postcode in England, Wales, and Northern Ireland. The postcodes locations are deduplicated by a process that ensures distinct points are approximately 50 metres apart. This process removes the bias that would otherwise come from counting the same crimes several times in heavily populated areas.
Using a custom algorithm developed in-house, CrimeRate applies a crime severity weighting to each area's crime counts, based on the type of crime reported. This increases or decreases the crime count, or zeroes it out entirely, depending on the crime type. A separate crime severity rate is then calculated, standardised, and scaled to fit the crime risk score range of 1 to 1,000, with 1 being the lowest score, and 1,000 the highest.
Crime risk scores undergo further analysis per town, city, and village plus other areas including police forces and neighbourhoods. CrimeRate uses percentiles to work out the most common range of crime risk scores in each locality. This includes identifying the high and low bounds where approximately 68% of scores fall, and finding the median (50th percentile) for easy reference.
The crime types with a weight of zero are: Anti-Social Behaviour; Bicycle Theft; Other Crime; Other Theft; and Shoplifting. The highest weights to are assigned to Violence & Sexual Offences, and the lowest to Vehicle Crime.
