The current counties of England are defined by the ceremonial counties, a collective name for the county areas to which are appointed a Lord Lieutenant. The office of Lord Lieutenant was created in the reign of Henry VIII. The Lord Lieutenant is the chief officer of the county and representative of the Crown. Whenever the Queen visits an area she will be accompanied by the Lord Lieutenant of that area. Legally the ceremonial counties are defined by the Lieutenancies Act 1997 as ‘Counties and areas for the purposes of the lieutenancies in Great Britain’ with reference to the areas used for local government.

Counties were formerly administrative units across the whole of the UK. Due to various administrative restructurings, however, the only administrative areas still referred to as 'counties' are the Non-Metropolitan Districts of England. The English Metropolitan Districts, although no longer administrative units, are also used for statistical purposes.

The Counties area list contains 35 areas of the following constituent English geographies:

• 27 Shire counties
• 6 Metropolitan counties
• Inner London and Outer London

Please visit ONS Beginner's Guide to UK Geography for more info.

The boundaries are available as either extent of the realm (usually this is the Mean Low Water mark but in some cases boundaries extend beyond this to include off shore islands) or

clipped to the coastline (Mean High Water mark).
