The latest published Immigration Statistics detail the number of asylum seekers accommodated in each local authority area. These statistics can be found at https://www.gov.uk/government/statistical-data-sets/asylum-and-resettlement-datasets#asylum-support
Data is published on a quarterly basis, with the latest information published 25 February 2021. The next quarterly figures are due to be released in May 2021.
The Home Office does not publish a breakdown of these statistics which disaggregates the number of asylum seekers accommodated in dispersal accommodation for the first time in each quarter in each of the last two years, by local authority. These figures are not available in a reportable format and to provide the information could only be done at disproportionate cost.
