Help notes and Frequently Asked Questions

The data

Humberside Police provides crime and anti-social behaviour incident data to the company contracted by the Home Office and the NPIA, Rock Kitchen Harris. The Association of Chief Police Officers has signed an agreement with Rock Kitchen Harris on behalf of all Chief Constables.

This agreement specifies and limits the way in which they use this data only for the purpose of converting the data into the agreed format for publication on the Street Level Crime website.

The data is provided on a monthly basis direct from Humberside Police’s crime recording system and, in the case of incidents of anti-social behaviour, the incident recording system. Both these systems are used to manage the actions relevant to the investigation of crime and response to reports of anti-social behaviour.

This means that in some cases the data may still be subject to change when it is provided to the Street Level Crime website, e.g. a crime may be finally recorded as ‘no crime’ because enquiries reveal that no actual criminal offence took place, or it may be established that an incident initially described as anti-social behaviour may fit a different descriptor.

For this reason, the data may not compare directly with data provided by other processes, e.g. British Crime Survey, responses to Freedom of Information requests and information given by the police at local community meetings.

Points on the Map

The points on the map at which crimes/incidents are shown are called ‘snap points’ and are not the exact location the crime/incident occurred. These points are allocated as follows:

  • Only to streets of 12 or more properties
  • If a crime/incident occurs on a street with less than 12 properties, it is included in the figures for the nearest street of 12 or more properties. This means that some streets will be displayed as being the location of crimes/incidents that actually occurred on neighbouring streets – the comments box will state ‘On or near to xxx Street’.
  • In rural areas where there are very view properties, a crime/incident will be allocated to the nearest street in a 20 mile radius of 12 or more properties. If there is no street of 12 or more properties within a 20 mile radius, the crime/incident will not be shown on the map.
  • The comments box will point to the street – the location of the snap point is aimed to be the centre of the street’s length and in the centre of the roadway – the snap point does not indicate that the crime/incident occurred at any specific property in the street.
  • Where there is a public building, e.g. hospital, police station, council offices, parks, the snap point will be placed at such locations
