Crime Risk Scores

Blackfen • 12 Months Ending April 2026

 

The typical five-minute walk within Blackfen has a crime risk score of 262. This is based on analysis of 11 nearby areas within Blackfen, with "most" referring to roughly two thirds of the nearby locations.

Five Mins
262 crime risk score
Ten Mins
365 crime risk score
Fifteen Mins
422 crime risk score

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 Blackfen's risk scores as, for example, robbery, or violence & sexual offences.

Within a five-minute walk of the typical location in Blackfen, crime risk scores are typically around 262, while in Bexley they are average 440.

Areas within a ten-minute walk typically see crime risk scores of 365 (538 for Bexley), and scores within a fifteen-minute walk are most often around 422 (Bexley 593).
