Table 2 shows some data related to crime in different areas of England. When answering the questions that follow, assume that the rates of offences in each area in the year ending September 2019 are valid indicators of the current annual risks of these offences.

Table 2 Rates of police recorded crime for burglary and violence against the person for selected areas of England and Wales, year ending September 2019
