Classification through consultation: public views of the geography of the e-Society

Although viewed by business and commerce as successful solutions, geodemographic profiling of neighbourhoods has attracted wide-ranging criticism in the academic literature. This paper addresses some specific concerns that arise because the derivation of classifications is rarely transparent and open to scrutiny or challenge. The substantive focus of the research reported in this paper is a nationwide geodemographic classification of how people engage with new information and communication technologies (ICTs). In response to the critique of geodemographics as a ‘black box’ technology, we describe how the classification was opened up to public scrutiny and how we conducted a major consultation exercise into the reliability of its results. We assess the message of the 50,000+ searches and 3952 responses collected during the consultation exercise, in terms of possible systematic errors in the shape and detail of the classification. Unusually for Internet-based surveys, we also investigate the likely reliability of the response information received and identify ways in which the outcome of consultation might be used to improve the classification. We believe that this is the first-ever large-scale consultation survey of the validity and remit of a geodemographic classification and that it may have wider implications for the creation of geodemographic classifications.

Creating open source geodemographics: Refining a national classification of census output areas for applications in higher education

This paper explores the use of geodemographic classifications to investigate the social, economic and spatial dimensions of participation in Higher Education (HE). Education is a public service that confers very significant and tangible benefits upon receiving individuals: as such, we argue that understanding the geodemography of educational opportunity requires an application-specific classification that exploits under-used educational data sources. We develop a classification for the UK higher education sector, and apply it to the Gospel Oak area of London. We discuss the wider merits of sector specific applications of geodemographics and enumerate the advantages of bespoke classifications for applications in public service provision.

Genesis: How to Build a Planet

John Conway’s “Game of Life” was one of the first things I ever wrote in Java, back in the days when we were using 1.1. This is a slight variation on the traditional 2D view, where the alife simulation is wrapped around a spinning globe. The results are shown below, along with the link to […]

From Tile Pyramids to Population Pyramids

It’s actually a stacked bar chart rather than a traditional population pyramid, but the image below shows male/female population by age for all the output areas in England. The red thematic overlay is total population for every OA, which can be clicked to get the age group breakdown shown in the popup window. This map […]

The intent is to make a free trafic solution!<br/><br/>I think from my toughts, that some sort of free programing solution of how cars should interact in traffic should be built.<br/>As when to stop or go, or don’t crash.<br/><br/>The free solution is to make lines, and adapt the objects to Path constrain, and animate them, from here to there… Tricky but you can do it…

In general we know how to model buildings, thats not too tricky – ours in the render are simply placement models for the street network. <br/><br/>The tricky part is modeling traffic simulation within a city model using software that is not at the $$$ level
