This is a question that needs to be asked because the UK’s approx. 2,500 postcode districts vary massively in size – from 2.33 hectares in London WC1A to 85,165 hectares in LD3 in Wales. And they vary just as hugely in residential and daytime population. For example, CR0 in Croydon, London has a residential population of 153,812 and UB11 in Hillingdon has just 2.
The answer – I would suggest – it to measure crime or type of crime total per hectare. That is a unique feature to UKCrimeStats. You can run a report and it will show you the top 100 highest/lowest , total crime, crime rate, crimes per hectare, crime rate per hectare between your choice of dates.
