Somehow this passed me by but http://local.uk.msn.com/ now includes some socio-economic data at a national level.
The crime information is worth a look and appears created from Experian data using the British Crime Survey rather than actual crime occurrences – then interpolated some how into a surface. Additionally, when you click the map, the data returned includes a series of the long descriptive profiles for the Mosaic Types or Groups within the “area” (however defined).
I really do worry about these types of commercial representation, specifically given the lack of detail over the methods used and the potential consequences of their erroneous interpretation. The information reported on this page about the crime data: http://money.uk.msn.com/MSN-Local/help.aspx#C appears to be all about perceptions of crime, which is very different from actual crime – as specified on the map. I am guessing that the crime map is created by taking the British Crime Survey, appending Mosaic, modeling weighted values for “perception” / fear of crime – then taking these values at postcode level and interpolating between them, probably with IDW into high / low scores.
The potential for creating spurious values is HUGE given so many uncertainties – at some point in this operation, a categorical value from a black box geodemographic is used to model a continuous point score, not to mention the fact that further values are then interpolated between these points in the conversion to a raster surface. To me, this really doesn’t sound like a set of plausible operations – why not just plot the crime domain of the IMD like we do on LondonProfiler?
Today was a jolly nice day with Ollie and I winning the Ordnance Survey Geospatial Mashup Challenge at GISRUK 2009. There were some really good entries and I was quite surprised with the result. One site which really impressed me was: “User Adaptive Trip Planner -Ramya Venkateswaran, Pia Bereuter, University of Zurich – hopefully this will be online soon”.
Our winning site is was titled “Contextualising Educational Careers for Widening Participation in Higher Education”, however is really a nice educational atlas. This should be online soon with luck, but here are a few slides to view for now:
And a short youtube:
I just presented this paper at GIS Research UK (GISRUK) in Durham sparking an interesting debate about ethics and use of transactional data. This is my first attempt at Keynote on OSX / Macbook – which after an initial failure at getting technology connected I am very impressed by overall.
I have just published a new working paper:
Computer mediated communication and the Internet has fundamentally changed how consumers and producers connect and interact across both real space, and has also opened up new opportunities in virtual spaces. This paper describes how technologies capable of locating and sorting networked communities of geographically disparate individuals within virtual communities present a sea change in the conception, representation and analysis of socioeconomic distributions through geodemographic analysis. We argue that through virtual communities, social networks between individuals may subsume the role of neighbourhood areas as the most appropriate units of analysis, and as such, geodemographics needs to be repositioned in order to accommodate social similarities in virtual, as well as geographical, space. We end the paper by proposing a new model for geodemographics which spans both real and virtual geographies.
