In the May 2025 edition of this publication, we issued a notice informing users that we had identified an issue with the sub-ICB, ICB and Region breakdowns affecting all financial years from 2019/20 to 2023/24 inclusive.
This issue meant the figures in the “Unknown” group were much higher than they should have been.
This issue is now almost entirely resolved. There is, however, a minor outstanding issue affecting a limited amount of subnational 2019-20 data.
As a result, metrics ASD16f, ASD16g, ASD16h, ASD16i, ASD16j, ASD16k, ASD25, ASD25a and ASD25b within the ‘AutismStats_Apr2019_Mar2020_Region’ and ‘AutismStats_Apr2019_Mar2020_ICB’ CSV files are currently omitted. All other files contain the full set of metrics across the full time series
NHS England apologises for any inconvenience.
