A small error occurred in the actives data (table 3.1b) covering 6 districts within Northern Ireland and the 4-year survivals data (table 5.1b) between Camden and City of London. These were due to processing errors with the geography codes on those tables. We have corrected these errors for the 2018 data.
You can see all previous versions of this data on the previous versions page.
We apologise for any inconvenience caused.
