The division into counties is one of the larger divisions of England. Counties are usually divided into several districts, each with its own separate administration (districts may be called Boroughs in some cases).
Counties which consist of only one district are more popularly called Unitary Authorities, because they do not match the idea of a county established in the centuries before the 1990s. However, not all unitary authorities are counties.
The county councils of these were abolished in 1986 by the Thatcher government for largely political rather than practical reasons, but they still exist legally. They are used for some administrative and geographic purposes, and are still ceremonial counties also. Most of the powers that they used to have have devolved to their metropolitan boroughs, which are now in effect unitary authorities, however some functions such as emergency services, civil defence, and public transport are still run jointly on a metropolitan county wide basis.
For 39 of these, they are defined as a county with a single district, which has a district council, and no county council. For the Isle of Wight, technically it is a county with a county council and no district councils, but the effect is the same.
The districts of Berkshire are unitary authorities, but are not granted county status.
The Isles of Scilly are not part of Cornwall for administrative purposes, but neither do they constitute a county.
Additionally there was a County of London which covered the area today known as Inner London. The Isle of Wight was originally included under the administrative county of Hampshire but obtained its own county council in 1890.
Some exclaves that had been left untouched by the 1844 Act were affected by this one, for example the Measham area of Derbyshire was placed under the control of Leicestershire County Council.

This map follows the usual practice of not showing county boroughs. Instead, they were included in their 'host' county. When a county borough expanded into territory of a county that wasn't the one it came from, maps often showed this as an increase in size of the county the county borough was associated with. So, for example, Bristol south of the River Avon would be shown as part of Gloucestershire rather than Somerset.
This system was the basis of the ceremonial counties used for Lieutenancy - except that Cambridgeshire, Hampshire, Lincolnshire, Northamptonshire, Suffolk and Sussex were not split for Lieutenancy. (Yorkshire, however, was).
As urbanisation increased, and suburbs were built on a scale not seen before, the urban areas surrounding various towns and cities started to cross traditional county borders. Since boroughs, urban districts, and parishes could no longer cross county boundaries, the county borders were adjusted
Throughout the next century, debates took place about what should be done about local government in respect of the increasing urbanisation of the country. Proposals to expand or change county boroughs or to create larger urban counties were discussed, but nothing happened until 1963, when legislation was passed to come into effect in 1965.
The report proposed that most of England the two-tier structure be abolished, and replaced with a system of 58 unitary authories, which would generally ignore the previous administrative boundaries in favour of changes that made geographic sense - a total redrawing of the map. In the metropolitan areas of Merseyside, South East Lancashire and North East Cheshire, and the Birmingham area, there would be 3 metropolitan areas, with 20 district authorities.
These proposals were opposed by the Conservative Party opposition led by Edward Heath. They won the 1970 general election, and set to work defining their own scheme. This scrapped the concept of unitary authorities (even for existing county boroughs) — the entire area of England and Wales was to be divided into uniform counties and districts. In England the counties were to be largely modelled on the existing counties, but in some areas (quite apart from the metropolitan areas) quite radical reforms were put forward.
Despite reassurances from the government that nobody's loyalties were expected to change as a result of the local government reform, and that the ancient and geographic counties would not be formally abolished; many changes did incur significant local oppositions. Most of the radical changes were withdrawn. One aspect the government stood firm on was the mergers of small counties. Campaigns for the continuation of Rutland and Herefordshire were unsuccessful, although due to its special geographic circumstances, the Isle of Wight was permitted to retain a separate county council, as opposed to being reunified with its historic county of Hampshire.
The Local Government Act was passed in 1972, and defined the English counties and metropolitan districts, but not the non-metropolitan districts. These were set by a Boundary Commission that had already begun work.
The metropolitan counties were composed as follows
In 1986 the county councils of the metropolitan counties, and the Greater London Council, were abolished by Margaret Thatcher's government following disputes with central government, but the counties themselves remained legally in existence.
The 1990s led to the restoration of county boroughs under a new name, unitary authorities, which radically changed the administrative map of England. The changes were carried out in several waves.
On April 1, 1995, the Isle of Wight became a single unitary authority. It had previously had a two-tier structure with an Isle of Wight County Council; and a Medina Borough Council and a South Wight Borough Council. Also on this day, two small areas were ceded from Surrey and Buckinghamshire to Berkshire, giving it a border with Greater London.
The incoming Labour government under the leadership of Tony Blair had made it a campaign pledge to establish some form of local government for all London, whilst being keen to stress that it was not going to be a resurrection of the Greater London Council. The Greater London Authority has an elected Mayor and an Assembly with scrutinizing powers.
