  1. The boundaries of England's Government Offices for the Regions
  2. The boundaries agreed by the Scottish Executive, National Assembly for Wales, and Department of the Environment in Northern Ireland.
  
  There are 28 agglomerations in the UK. An agglomeration is defined as any urban area with a population greater than 250,000.
