Perhaps the world’s most famous historical geodemographic maps, the London Poverty Maps were created by Charles Booth over the course of a decade in the late 19th century, exhaustively colouring each individual house in the capital, on the basis …

I’ve just now published a number of maps on the CDRC Maps platform which uses the DataShine mapping style (more about DataShine) to show demographic data relating to consumer and other datasets. The maps relate to the Indices of Deprivation 2015, small-areas measure of deprivation in England, which were compiled and published at the end … Continue reading Changes in Deprivation in England, 2010-15 →

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 […]
Continue reading »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, […]
