Question to the Home Office:

To ask the Secretary of State for the Home Department, at what level her Department values the reduction of risk of death per fatal casualty prevented; and if she will give an example of policy intervention where this evaluation was made.

In order to estimate the cost of a homicide, the Home Office uses the value of
a prevented fatality, which is estimated by the Department for Transport. The
Home Office has produced three reports on the economic and social costs of
crime, which contain the department's estimates of the value of preventing a
fatality in relation to a homicide. The Home Office first estimated the
economic and social costs of crime in 2000:

The Home Office last comprehensively updated the costs of crime estimates in
2005:

The Home Office's 2011 publication provides its most recent revision to the
unit costs of crime figures:

The costs within the costs of crime report are used to inform policy
development. For example, the rationale in the impact assessment for Domestic
Violence Disclosure Scheme refers to the average and total cost of homicides
related to domestic violence and abuse:
