Comparing Geodemographics with IMD

In the last post but one I discussed the English Indices of Multiple Deprivation (IMD). In this post I introduce the Geodemographic Classification created from the 2001 Census by various academics for the Office of National Statistics. It originally was classified at Output Area but I am using the larger unit classification of Lower Super Output Area that was published in 2008. Guidance can be found here and the data here.

National Statistics 2001 Area Classification of Lower Super Output Areas showing Supergroups, Groups and Subgroups in the London Borough of Camden

Comparing Area Classification with IMD ranks (the lower the rank the higher the deprivation)

The reason I have used the LSOA scale is that it allows comparison with the IMD. I have shown this above. I have devised a hybrid scatter graph to display the combination of ordinal data - IMD and nominal data - the geodemographic to aid in understanding the similarities and differences between the two datasets.

The table above gives an example of IMD and Area classifications being used for analysis purposes. This comes from a relevant and interesting recent publication that I will return to in later posts.
