One of the difficulties in comparing how deprivation impacts on child protection and looked after child rates in the four UK countries is that each country has a different way of calculating its Index of Deprivation. There is overlap, but they are all different.

Using a methodology which was established in 2012, Professor Tim Sparks, the team's statistician, has produced a composite UK wide Index which ranks small neighbourhoods in all four countries on a single scale so they can be compared. This takes account of the recently published updated indices in England, Scotland and Wales. We think this will be useful to a wide range of researchers, and intend to publish a description of the work and share the data.
