2. Kautt UPTAP Workshop, 19 March 2008 British Crime Survey Data The British Crime Survey (BCS) is an in-depth, face-to-face victimisation survey that utilises a nationally representative sample of adult, private household residents
Although many studies use its data to examine a broad range of criminological questions
Few multivariate analyses use it to examine variation in criminological perceptions within and between Black and Minority Ethnic (BME) groups
victimisation
fear of crime
performance of the criminal justice system (CJS)
Existing multivariate studies largely rely on BCS data from years prior to 2001 To date few studies use multilevel modelling techniques to analyse BCS data
The current study remedies this by
Focusing on differences by BME status
Using single and multilevel modelling techniques
Using data from 2001 through 2006
This span enables exploration of how recent events (e.g. 9/11 and 7/7) may have changed how BME status relates to respondents’ criminological perceptions.
Examining three key dependent variable families
experience of victimisation
fear of crime
perceptions of the CJS
3. Kautt UPTAP Workshop, 19 March 2008 Additional Contribution This strategy incorporates a more specific measure of area than the previous research
Rather than geographical regions, it uses Police Force Area (PFA)/Criminal Justice Area (CJA) in the multilevel analyses
Results can be more readily translated into specific policy recommendations than those of previous research
These areas constitute geographically-based management divisions for the CJS since 2001
Provides a more specific view of the area characteristics that victimisation, fear of crime and perceptions of the CJS.
4. Kautt UPTAP Workshop, 19 March 2008 BCS Reported Victimisation Research consistently indicates that BME group members experience higher crime victimisation than comparable whites
However, the level of victimisation varies between specific BME groups
Studies focusing on the household or individual level
Identify several factors highly correlated with respondent ethnicity, which significantly affect victimisation risk, and vary by offence type
Strongly suggest interactive effects between respondent ethnicity, crime type and other factors predictive of victimisation.
Studies focussing on neighbourhood and region
Identify additional area-level factors, which significantly influence victimisation rates
Indicate that the effect of several characteristics (both household and area-level) varies significantly by geographic region
5. Kautt UPTAP Workshop, 19 March 2008 BCS Fear of Crime Although studies show that fear of crime often overestimates likelihood of victimisation, existing research suggests a strong connection between the two
Multivariate evidence examining BCS fear of crime shows that several factors predicting victimisation also predict fear of crime
Moreover, like victimisation, the constellation of factors affecting fear of crime also varies by crime type.
Research further suggests that area characteristics also significantly affect fear of crime
For example, greater area-level BME populations (measured independently for blacks and Asians) are associated with increased reported fear of crime
6. Kautt UPTAP Workshop, 19 March 2008 BCS Perceptions of the CJS Research indicates that perceived control over crime directly influences fear of crime
This suggests a link between fear of crime and perceptions of criminal justice system
Yet, multivariate analyses of BCS respondent perceptions of the CJS are uncommon
There are also conflicting results
Clancy et al (2001) find that being a member specific BME group significantly affects reported assessment of CJS agencies while Jansson (2006) does not uncover such effects
These disparate results suggest that further exploration is necessary to discern the connection between these factors
7. Kautt UPTAP Workshop, 19 March 2008 Research Questions What theoretically relevant factors significantly predict BCS respondent/household reported :
Victimisation?
Fear of crime?
Perceptions of the CJS?
Do the significant factors vary by the BME status of the respondent? (Overall, in terms of strength (magnitude) or direction of effect?)
Do the above patterns change over time (e.g. pre/post prominent events)?
Do the assessed outcomes vary significantly by the PFA/CJA within which the respondent/household is situated?
Do PFA/CJA level factors significantly predict the measured outcomes?
Do PFA/CJA level factors (notably ethnic heterogeneity and composition) significantly influence the respondent/household level predictors?
Do the effects of PFAs/CJAs and their characteristics vary by respondent BME status?
8. Kautt UPTAP Workshop, 19 March 2008 Theoretical Framework: Two Assumptions Victimisation, fear of crime and perceptions of the CJS are inextricably tied to one another as well as to culture, locale and ethnicity
In relation to locale and views of crime, Jackson (2004: 946) notes: ‘…public attitudes toward crime express and gather meaning within a context of judgements, beliefs and values regarding law and order and the social make-up of one’s community and society’
He later ties this to culture and ethnicity, observing: ‘incivility may also symbolize the presence of a variety of sub-cultural groups whose behaviour is seen as different or foreign, with differing values, norms and behaviour (Jackson 2004: 948)’ Ethnic experience is more individualised and context-dependent than empirical research generally takes into account
This research aims to embrace and incorporate different minority perspectives in order to better discern ‘the role of ethnicity (‘whiteness’, ‘blackness’, ‘Asianess’, or some ‘otherness’) in explaining offendings, victimization and criminal justice practices (Phillips and Bowling 2003: 271)’
9. Kautt UPTAP Workshop, 19 March 2008 The Data BCS
Data from 2001 through 2006 provide the three families of dependent variables and the respondent/household level control variables
Because ethnic minorities comprise only a small proportion of the BCS sample (approximately 10% for all BME groups combined), pooling data across years will be necessary to meaningfully analyse responses by specific ethnic group for some analytical models.
Data from PFA/CJA level
This information, whilst pre-existing, is not available in a single data set
Data are manually compiled from available sources
2001 Census and published reports
the National Audit Office, Crown Prosecution Service, Her Majesty’s Court Service (HMCS), Department for Constitutional Affairs (DCA), the Police Service, the Home Office
These two data sets will be linked via the PFA identifier present in BCS data from 2001 onward
10. Kautt UPTAP Workshop, 19 March 2008 Analyses The following analyses will first be conducted on ethnically pooled data before being run on subsets representing different BME groups
The coefficients from subset analyses will be compared via the z-test for equality of coefficients to indicate whether the same factors influencing DVs in the ethnically pooled analyses hold true for specific BME groups or if their significance and magnitude changes with the ethnicity of the respondent
Single level analyses estimating
The significant predictors of the DVs, interaction effects
Multilevel analyses to determine
How PFA/CJA level factors affect the respondent level dependent variables
How the effect of respondent level factors varies by PFA/CJA (random effects)
Estimations of how much of the variance in the dependent variables is explained by both the PFA/CJA and PFA/CJA-level factors
Exploratory time-series analyses
11. Kautt UPTAP Workshop, 19 March 2008 Dependent Variables-Victimisation This is captured in two ways
Prevalence : the likelihood of being victimised
Modelled as a dichotomy at the respondent/household level
Responses will initially be categorised as victimised (1) versus non-victimised (0).
From this, cases where victimisation is reported can be further analysed by victimisation type where incidents are categorised as acquisitive (0) or expressive (1). This can be further refined such that acquisitive victimisations are compared against one another
Logistic regression will be used to identify which case-level factors significantly predict the type of victimisation experienced
Incidence : the number of times one has been victimised
Incidence is captured as a right and left-censored count variable
The same comparative approach outlined for prevalence will also be applied to incidence. In other words, the prevalence of general victimisation incidence will be modelled first, followed by independent models of acquisitive and expressive victimisation incidence and so forth.
Negative binomial and Tobit analysis will be used to model this outcome
12. Kautt UPTAP Workshop, 19 March 2008 Fear of Crime Represented in two ways
A scale from 1 to 10
1 represents fear of crime having no effect over the respondent’s quality of life and 10 represents a total effect
Ordered Logistic Regression will be used to model this dependent variable
A ‘fear of crime’ index, based upon a compilation of respondent responses on a series of ordinal questions dealing with fear of crime, will be constructed
These include questions as to whether the respondent ‘feel(s) safe walking alone at night’ as well as ‘during the day’ and if s/he ‘worr(ies) about being the victim of crime’ in a reverse ordinal scale as well as dichotomous indicators for fear
This yields a right and left bounded, interval-level variable which will be analysed with both negative binomial and Tobit analysis
13. Kautt UPTAP Workshop, 19 March 2008 Perception of CJS This is captured in two ways
A series of dichotomies
These BCS questions directly ask respondents if they view ‘too lenient sentencing’ and ‘too few police’ as major causes of crime in Britain
Analysed via Logistic regression
An index score based on a series of four-point reverse ordinal scales assessing respondent confidence in various aspects of the CJS
These several include several four (e.g. ‘effectiveness’ and ‘confidence’ measures) and five (e.g. ‘how good a job’ or ‘satisfaction with contact’) point scales for assessments of both the CJS generally as well as specific CJS elements (e.g. the police, the juvenile courts, the Crown Prosecution Service, etc.)
modelled using Negative Binomial and Tobit analysis

In the BCS data, these are combined into a single variable capturing both
Here disaggregated by race to look at ethnicity (only Asian) independently
Differences in sample size may account for the results shown here
If so, it addresses the utility of BCS data in examining BME issues
If not, it shows striking results
