Mapping GCSE Scores

In the UK, August is exam results month for 16-18 year olds. Every year, photos of leaping teenagers clutching their results are accompanied by reports of record attainment rates, debates around how challenging modern exams are and, more so recently than ever, concerns for the number of sixth form and university places. Back in March …

Exploring the Historical Determinants of Urban Growth Patterns through Cellular Automata

Kiril Stanilov has adapted RIKS METRONAMICA, an established cellular automata (CA) modelling system, to simulate the historical growth of a section of a large world city. The focus is on simulating change from the late 19th century until the modern …

London Index of Multiple Deprivation Cartograms

On my previous post I talked about the Index of Multiple Deprivation (IMD) in a London only setting. A common trait with the maps I created and those you can find elsewhere is the use of LSOA boundaries that reflect the geographical reality of the lay of the land. When concentrating on London in particular this does have an impact on how you perceive deprivation. This is in part down to how Lower Layer Super Output Areas (LSOAs) are constructed. An LSOA by design has to contain at least 1,000 residents and 400 households, with a national average of around 1,500 residents. London of course does not just consist of the denser populated core, but also more rural areas on the outskirts. As the methodology dictates that each LSOA has to have at least 1,000 people in it, the geographical extent of LSOAs tends to be larger in these more rural areas. This means visually they will be more dominant than central areas and can give a “false” impression as to how much of London’s population live in either more or less deprived areas. In an attempt to try and address this visualisation problem I have used the Cartogram Geoprocessing […]

The London Index of Multiple Deprivation

The Index of Multiple Deprivation (IMD) is a measure of the “deprivation” of any given area. A combination of indicators covering a range of economic, social and housing issues, allow for a single deprivation score to be constructed, and these scores are then ranked. The data for the 32,482 Lower Layer Super Output Areas (LSOAs) that make up England was released in March 2011 for the 2010 IMD. This showed the rank of each LSOAs deprivation, ranging from 1 to 32,482. Fortunately due to a similar methodology being used to construct the 2010 IMD, it possible to compared it with the previous IMD released in 2007. Instead of focusing on a national scale I have re-ranked the data for London’s 4,765 LSOAs for both the 2007 and 2007 IMDs. Each of the 4,765 LSOAs have had their new ranks split into deciles, which is what is displayed on the maps below. This means there are roughly 476 LSOAs in each decile, or one tenth of all the areas in the dataset. Move your mouse over the picture, to swipe between the 2007 and 2010 London IMD. Show dividing line? I was inspired to use the “scrubber” technique by Oliver O’Brien, […]

Welcome to my blog!

TweetI didn’t want to leave a blank space while I am still constructing my first blog post, so I thought I would introduce myself and give you some idea of the work I am doing. My name is Chris Gale and I am in the first year of my PhD at University College London. The main theme of my PhD is to create better area classifications for the 2011 Census in partnership with the Office of National Statistics. An important part of this will be while a new classification methodology will focus on the 2011 Census, it will not be limited by it as other data sources will be used. I shall also be looking at new modes of dissemination that better utilise web technologies and new advances in GIS and geodemographics. Currently in-between lecturing a GIS course at Kingston University London and demonstrating on various courses at UCL I have been focusing my attention on OAC and London. I will go into more detail at a later date but I find this to be an interesting starting point for my research. This is mainly due to OAC classifying a large proportion of London as ‘Multi-cultural’, asking the question, can London be included within any national classification in […]
