The document discusses mapping the fear of crime through a web-based GIS solution that captures vernacular or 'fuzzy' geography, emphasizing the subjective nature of people's perceptions about crime in their local environments. It highlights how these perceptions often do not align with actual crime statistics, influencing behaviors and creating 'no-go' areas. The study showcases a case in West Yorkshire, detailing methodologies for capturing these perceptions in a way that respects the ambiguity of everyday language used by residents.

1. Mapping the Fear of Crime, a Web Based GIS Solution to Capturing “Fuzzy” Geography – or Andy Evans – Leeds University http://www.ccg.leeds.ac.uk/ Centre for Computational Geography, School of Geography, University of Leeds Leeds, UK, LS2 9JT Tim Waters – Bradford Council http://www.bradford.gov.uk Jacobs Well, Bradford, BD1 5RW what “the dodgy area near me Gran’s” means

2. In Brief The Geography of everyday – the vernacular. Fear of crime, and how to map it What sort of results can we get What can we do with these results

3. How do people relate to the world? How people relate to the world Fear of Crime Capturing vernacular geography Using vernacular geography Case study on West Yorkshire Town

4. Affects our behaviour The way we perceive areas directly influences most of our day-to-day activities. Go to the shops for lunch Avoid the bad bit of town Move to the suburbs But we have no clear geographical idea of where these areas are! How can we even attempt to map “ the dodgy area near me Grans ” ?

5. Vernacular Geography Locational “ Downtown” “ The East End” “ Mount Snowdon” Loaded: “ High crime area” “ Posh part around the park” “ The grim area of town ”

6. Think GIS? Pretty much everyone: Doesn’t think GIS Uses geographical terms they cant define Mixes up attribute datasets Rarely puts anything precisely on a map Causes a problem for the crime mappers!

7. Its Good & Important Defines areas that constrain our activities “ I wouldn’t walk through the rough part of town alone ” This constraint should be shared, and acted upon “ that’s a pretty high crime area ” BUT! Hard to tie into objective “true” data “ We need more police here” “ She walked through the crumbling old hilly part of town ” Gives us geographical information with built in data about environmental, socio-economic and architectural attributes.

8. Vernacular is also fuzzy Fuzzy boundaries occur: Continuousness Where does a mountain start? Crime hotspots – lukewarm? Aggregation Soil types Averaging River on a map Ambiguity Definition of “high” crime areas

9. Fear of crime example vernacular = fuzzy If you asked 10 people in the street: Define and explain areas where they are afraid to walk in the dark: Datasets people use are continuous and discrete at differing scales, historical, architectural, temporal and mythological. “ Smart end of town” “25 Cromwell Street” Areas are linguistically ambiguous Areas may by bound by landscape (I.e. “ within the ring-road ”) but more usually diffuse Often have different levels of intensity with the areas Differences between people.

11. Importance of Perceptions Susan Smith (1989) summarises fear of crime: “ Fear is more than simply awareness about crime, and more than concern about the problem of local deviance. …Rather, fear is a state of constant or intermittent anxiety : its effects reach beyond the prudent management of risk to impinge on public morale, individual well-being and the quality of social life.” Garofalo (1981) connects fear of crime with the environment; “ an emotional reaction characterised by a sense of danger and anxiety …produced by the threat of physical harm…elicited by perceived cues in the environment that relate to some aspect of crime ” “ fear of crime will grow unless unchecked. As an issue of social concern, it has to be taken as seriously as…crime prevention and reduction ” (Home Office 1989).

12. Reality != Perception but Perception > Reality Most studies: The pattern of fear does not equal the pattern of reality “ Although fears of being victimised are widely held and influence behaviour in space, they are out of proportion to real levels of risk ” (Evans 1989) “ It is the fear, often exaggerated , of victimisation which creates most of the stress… The police actually witness and discover very few offences, citizen vigilante groups have disbanded out of the frustration of seeing nothing to report; crime prevention should focus on its passive role of allying fear as well as on its active role as a deterrent to offenders.” (Herbert 1982) This may seem controversial. Why exaggerate? So is Fear more important?

13. Effects of Fear of Crime It ruins the sense of community and makes some places “no-go” areas. Wealthy people protecting themselves or moving from the area, this may lead to crime being displaced onto those already suffering. It could lead to people being disillusioned with the criminal justice system, with a feeling of helplessness. This could lead to vigilante groups or even lynch mobs. When people are afraid, they change their habits. They tend to stay at home more. When they go out they avoid “dangerous” activities like taking public transport, walking down a certain road, being near certain “types of people” etc. For people fearing victimisation at any time, a journey outside the home, (or even within it) is “ like walking through a minefield”

14. What Influences Fear? Mass media. More column inches about crime = more fear Direct experience of crime. Interpersonal communication about another’s experience. politics! Conservative Advert "This misleading advert quite improperly seeks to stir up fear of rising crime when it is a well established that crime has been falling for years". Richard Brunstrom, chief constable, North Wales Police 1 April 2005

15. More influences Environment: Litter, graffiti, noise, dereliction, abandoned cars. Anti-Social Behaviour: Drunks, gangs of youth etc. Confidence in the Police and authorities. Perceived seriousness of offences. Labelling and reputation of areas.

16. Mapping Fear of Crime Some studies done: Drawn dots on the paper map with pens Asked about areas – but constrain area in polygon Crayons to specify boundaries – then digitised Doesn't take into account vernacular geography. Hard work too!

18. Fear of crime example Define and explain areas where they are afraid to walk in the dark: Continuous and discrete at differing levels: spatially & other Areas are linguistically ambiguous Areas more usually diffuse – no firm boundaries Levels of intensity within the areas “ The dodgy area near me Grans” How can we record this on a map? And would it be easy to do?

19. Capturing vernacular data Input: A spray-can interface for a online GIS, that allows areas to be mapped and comment attributes to be attached. Storage and analysis: A compression & combination component Output: A way of representing all users’ data and searching for the comments in order of users’ perceived importance.

20. Input GUI User sprays on map Change spray size Adds new areas Wipe the map Writes in comments When done clicks on “send” button

21. Storage & Analysis Aggregation Average of all inputs Compression Weighting Admin access Moderation Extract

22. Query GUI User clicks on map Ranked Comments Displayed

23. System Details Continuous vs. dots Continuous: Ready made density Dot density: Easier to use. Harder to convert into a density map.

24. On the internet File sizes – traffic & processing costs Could make smaller: Clipping esp. if sprayed small area Complex gradient mapping. Vector paths Basically Raster is easier. Raster layers with lots of variation Raster is big! Solution : Compression

25. Compression WHY? From 859K to 14K !! E.G. a combined image and data object of 859Kb was compressed to 67Kb just using the GZip algorithm, and further compressed to 14Kb with the addition of the shrinking process. Other algorithms could improve on this. User dots Density map Shrunk to 1/5 size GIF style compression GZip Sent

26. Averaging - User tests suggested a 9x9 pixel averaging kernel best represented the areas users had drawn using the dots. - Tests suggested this could be shrunk to 5 times the size and re-inflated without users noticing a significant change in the image.

27. System Details – 2 flavours Applets & Perl CGI Easy and quick to set up, but slow Applet & J2EE servlet ( this example ) Lighter, stronger but harder to set up input Query (Admin) server input server query admin

28. System Developments Desktop GIS tool Zoom, pan tools Stronger admin / moderation Easier GIS export

29. Case Study How people relate to the world Fear of Crime Capturing fuzzy geography Using fuzzy geography Case study on West Yorkshire Town

30. Case Study - Keighley 47,000 people Rural centre: Services over twice that number - Urban and rural crime 2003-4 Around 9569 crimes (108 crimes per 1000 pop) Keighley Bradford Bradford District

31. Keighley Live Study Questionnaire Input Output

32. Comments Guard House estate is probably the worst of Keighley's large estates for high crime. Anti social behaviour around the station and shops These area elected the BNP – (hate crime). Town centre is worst. The last question 'what would make you feel safer' encourages dependency on services and precludes personal involvement. My perceptions are that Keighley is generally safe, but that crime/anti-social behaviour takes place around the railway station/Chrome however I generally feel safe during the day/when there are people around There will always be a perception of crime in all areas including on your own door stop. Known areas of crime are in areas typical of early council housing estates. Utley drug dealing in woods near Cliffe Castle About areas, about persons experiences, meta, specific problems

33. Results Real density Combined inputs Recorded - Perceived

34. What the results tell us “ toy” analysis? For us: “ where do people have mis-perceptions as to the level of risk from crime?” (If areas don’t match) “ what level of crime do people notice as high?” If areas match) What areas (don’t) have a bad reputation? For users: “ How scared of crime are my neighbours” “ Does anyone else feel the same way as me”

35. Other Uses Fuzzy Logic Demographics Geodemographics for highlighted areas Questionnaires Familiarity Analysis of comments

36. Issues Open to public on the net Legal & ethical issues vs e-govt Moderation / Bias / censorship How the maps designed. Cartography. Aerial photos? Do people know where the areas are? Chapeltown & Chapel Allerton (Leeds) Vernacular areas not the same as GIS areas 3 Keighley wards, town council, neighbourhood, SRB, constituency etc… ?

37. Further work Larger public study System Web based system Desktop GIS Analysis Fuzzy Logic Disaggregate results Comparative studies Other applications– Where is the East End anyhow? Where has the best food in UK?

38. Summary How people refer to areas Vernacular / fuzzy geography Perceptions of crime How we can capture it on a map What it can tell us Now we can map “ the dodgy area near me grans ”
