Apologies for the late update, something is happening with the ONS website that meant I couldn't find the latest release using my usual search. I did eventually find it when looking for something else.

People have asked about the latest Index of Multiple Deprivation (IMD) statistics. These haven't been updated in this release. I will now investigate including this data from the original sources.
If you spot any problems, let me know
