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

Region	Burglary	Violence against the person
Cleveland	9.4 per thousand of population	41.4 per thousand of population
Gwent	0.63%	3.47%
London	1 in 109 of population	1 in 41 of population
Norfolk	0.0038	0.0268

Give two reasons why a particular household in Norfolk may in fact be at a higher risk of burglary than the probability shown in the table.
