The Department for Transport publishes estimates of its total expenditure on services by region and country, including the west midlands, in its annual report. These figures rest on a number of assumptions, for example about how total expenditure on strategic highways and rail should be attributed to different regions.
These figures exclude grant to local authorities, as this information is collated separately by CLG, DCSF, DWP and devolved Administrations. Details of the Department's funding for local authorities in the west midlands, which in general is not ring-fenced to particular transport services, may be found at:
The annual report does not provide specific figures for Birmingham and an estimate could be provided only at disproportionate cost.
