Finding Buried Domestic
Abuse Through Mapping
Chris Sprange

Information Team
Why are we looking?
• Police under reporting
– Police data shows high levels of DA in
terraced and semi detached housing, low
levels in detached. Is this a reporting bias?
ARE VICTIMS HIDDEN IN DETACHED
HOUSES?
• Full Audit of domestic abuse

Key National Statistics - Numbers
Claims the lives of 150 women per year
Between 6% and 10% of women suffer
domestic abuse in a given year
Estimated ‘7 year’ survivor period from first
instance of abuse
www.saferderbyshire.gov.uk
Estimations for Derbyshire
150 Nationally per year
– 2 Per year in Derbyshire
In the 3 audit years April 01 to March 04
– 6 Unlawful deaths of women
ALL DOMESTIC RELATED
www.saferderbyshire.gov.uk
Estimations for Derbyshire
6% to 10% of women suffer domestic
abuse per year
In Derbyshire this equals 13,000 to 20,000
How does this compare to actual records?

Police Recorded Domestic Abuse
Not all correctly flagged
Automated key word checker used, followed
by manual check
Male victims and repeats removed
www.saferderbyshire.gov.uk
Estimations based on police
records
2,500 individual female victims identified
– Assume rates same each year
– Average 7 years before they are identified
Total number of victims per year
7*2,500 = 17,500
8% Exactly half way between national
estimates of 6% to 10%
www.saferderbyshire.gov.uk
Key National Statistics - Risks
• Women with income less than £10,000
were 3.5 times as likely to be victims
– Low paid work
– Low educational attainment
• Pregnancy is a high risk time
• Divorced or separated women have a
higher risk

Key Findings
• Detached housing numbers 4 times lower in
areas with high DA
• Council tenancies nearly 4 times higher in areas
with high DA
• Female unemployment rate 2 times higher in
areas with high DA. Lone parent households
over twice as high
• Elementary occupation rates, households
without a car and no qualification rates
significantly higher in high DA areas
www.saferderbyshire.gov.uk
Key Questions
• Are detached houses ‘hiding DA’ because
no-one can hear?
• Are council tenants more likely to be
willing to report DA since they don’t mind
moving?
• What can we do about the low educational
attainment and low income risk?
www.saferderbyshire.gov.uk
Citizens Panel
• Not police data – no bias/different bias?
• Another estimate of the levels of DA in
Derbyshire
• A way of comparing experiences of
women in detached v terraced housing
areas
www.saferderbyshire.gov.uk
Citizens Panel Results
• 8% of women respondents said DA
causes them relationship problems
– This agrees with the 8% (17,500) figure based
on National Estimates and Police records
• Over 11% of women said they were aware
of domestic abuse happening in their local
area

Citizens Panel Risk Analysis
• Same pattern as police data
• Detached housing rates significantly lower
for areas with domestic abuse
• High levels of council and terraced
housing = high levels of domestic abuse
• Suggests police crime data is
representative

Conclusions
• DA is hidden ‘under our nose’
• Where there are some cases of DA there
are likely to be more
• Resources can be targeted to specific
areas
• Social Services – Council Housing
• Support Services
• Changing perceptions - Education
