This publication brings together migration-related indicators, for councils and NHS Board areas, from different sources. It includes time series data up to 2019 to help understand migration trends at a local level. It is updated once a year, although some of the data may be available more frequently and can be accessed from the relevant sources specified.
The Office for National Statistics has also produced a Local Area Migration Indicators Suite which uses a lot of the same sources used in this publication, but looking at areas across the UK as a whole.
Please get in touch if you need any further information, or have any suggestions for improvement.
