Outline of presentation

  • Purposes of project undertaken

  • Categories of research aspects

  • Gaps in previous research

  • Sources of data

  • Data analysis

  • A simple statistical model

  • A simple mathematical model


Purposes

Purposes

  • To design appropriate Data collection and analysis techniques for peoples’ perception of crimes

  • Devise a model (mix of qualitative and quantitative) to establish the relationships among the factors of perception of crimes such as age, neighbourhood, crime categories in order to explore the gap between perception and reality; relationship between perception and fear of crimes

Gaps in previous research

Gaps in previous research

  • loss of information through the computational process

  • Unconvincing tackling of the issues of continuation of research on perception of crimes in the changing aspects of social circumstances

Data collection and analysis nature of data

Data collection and Analysis Nature of data

  • British Crime Survey, April, 2007-March, 2008

  • Mix of qualitative and quantitative

  • Experience of crime within 12 months prior to interview

  • 42 Police Force Areas (PFA) of England and Wales

  • Adults 16 over (focus on Representative individual) in Private House Holds

  • Sample size: 46, 983 including both victim and non victim

  • Unaffected by the changes in levels of reporting to the police, and police recording practices


Steps in data analysis

Steps in data analysis

  • Determining the contributing variables of perception of crimes

  • Evidencing the relationships among the variables through proper quantitative

    and qualitative analysis such as

    statistical modelling, data triangulation.

  • Devise a mathematical model

  • Confirming the results of mathematical model through a qualitative model

Parameters estimation

  • Dependent and Independent variables

    There are two different aspects:

    i. “locality reference” and

    ii. “perceived crime rate”

    “locality reference” will be measured through two different independent variables:

    a.‘home’: It covers the aspects of perception of crimes where people see the evidence of crime activities around the place where he or she lives in.

    b.‘remote’: It covers peoples’ perceptions about outside of their home. This sort of perception is formed through the reading newspapers, chatting with other people, watching films,etc.

The second dependent variable “rate of perceived crime” will be measured through four different qualitative measurements:

a.“perceived vehicle crime rate”

b.“perceived antisocial behaviour occurrences”

c.“perceived occurrences of burglary”

d. “perceived occurrences of drug and gang crime”

Some of the independent variables are the index asking the respondents what area code they are living in, how long they are living for, how they think the extent “people driving the above the speed limit”, “teenagers hanging around on the streets”, “people using or dealing drugs”, “Homes being broken into and property stolen” and “How many times they have felt fearful”.

  • Demographic variables

    The demographic variables are age, gender, ethnicity and area code.

i. x = X: {x1,x2,x3,x4}

where X=demographic variable and x1= Age; x2 = Gender; x3 =Ethnicity and x4 = area code ...............................................( i )
