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.

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 […]Continue reading »
Crowd, transport and urban simulations are at their roots down to ‘Agents’ or ‘Objects’ that are assigned a set of rules as to how to moves in relation to both the environment and other agents around them. 3D Studio Max has a built in ‘Crowd and Delegate’ system which can be used to assign behaviour […]Continue reading »

This review begins by acknowledging the success of geodemographics as an important area of activity in applied geography. However, it then develops a critique of the conceptual and computational underpinnings of the approach, and argues that changes in data supply and online communication have rendered current practices obsolete. It presents elements of a new perspective, entailing: changes in the specification, estimation and testing of online geodemographic systems; adoption of consultative practices from online folksonomies; automated generation of pen portraits; and
