Bicycle theft rates

There were approximately 0.1 bicycle thefts recorded for every 1,000 Trafford residents during December 2017. However, there is some variation in rates of bicycle theft between wards. Altrincham, Ashton upon Mersey and Davyhulme East wards recorded the highest rates of bicycle theft with 0.3 offences per 1,000 residents.

Location quotient

The location quotient (Brantingham & Brantingham 1997) provides a measure of the difference between the rate of crime in a ward and the rate of crime for the whole of Trafford. A location quotient of 1.0 indicates that a ward has a proportional share of crime whilst a value greater than 1 indicates a disproportionate share.

Figure 4 shows that Altrincham ward recorded almost twice the rate of bicycle theft during December 2017 as Trafford as a whole.
