Measuring the effects of crime. We wish to include, as part of a set of social statistics, measures of the amount of crime and of the impact of crime on people’s attitudes and activities. Suggest some possible measures in each of the following categories:

(a) Statistics to be compiled from official sources such as police records.

(b) Factual information to be collected using a sample survey of citizens.

(c) Information on opinions and attitudes to be collected using a sample survey.
