Shedding more light on the Dark Figure



This is yet another Venn diagram. I have been a little addicted  recently. This is taken from my 15 minute presentation entitled "Shedding more Light on the Dark Figure" which I gave on 7th December 2010 to the Crime Survey Uuser Group meeting. They have published it on the web along with the other presentations. They can be found here. Mine is the 2pm time slot.

Perceptions of Crime

I have been studying my Venn Diagram in the post one before the last decided that I can improve on it. This is not perfect but it is better. I actually like the diagram without the labels. Perhaps I should enter it for the Turner Prize entitled "Perceptions of Crime". OK.................. here it is with labels.

Linking Crime, Incident, BCS and Police Recorded Crime data sets

Posts to do with the the Metropolitan Police Service CAD and CRIS databases have been quite popular so I thought I would share a flow diagram that I have just created of how the data arrive in them. The other two data sets I am interested in - the British Crime Survey and Police Recorded Crime are also shown.

Overlapping Crime Domains

This is my latest Venn diagram trying to explain Crime: how it is measured/recorded and how it is perceived. I think it is reasonably self-explanatory. The interesting bits are the overlaps of the various domains. I am approaching this diagram from three different angles;

• Shedding more light on the "dark figure" a talk I am giving to the Crime Survey Users Group on Tuesday 7th December.
• Explaining the utility of police incident data in augmenting the other crime measures (BCS and police recorded crime) particularly regarding violent crime for a paper that I am writing, and
• My ongoing interest in describing the fear of crime.

The early history of crime maps with modern visualisation

I would like to draw your attention to a high quality paper (I have just discovered) that should be of interest to everyone interested in crime mapping. Its got it all, it has the history, the maps, the visualisation and a statistician who can write good English without feeling the necessity to resort to Ancient Greek lettering to make his point except where it is truly necessary.

This is an example of one of many maps within the paper. You will have to read it to find out what it is all about. The free .pdf can found here.
