Pan-Strategic Health Authority (Pan SHA)

Pan-strategic health authorities (Pan SHA) were based on the NHS's National Programme for IT. There were three programmes for NHS IT in England, each made up of an individual strategic health authority (SHA) (in the case of London) or groups of whole SHAs. Pan SHAs were not legal entities. They were confederations of SHAs, and any staff working as part of the pan SHAs were employees of the SHAs. Pan SHAs replaced IT clusters as a health geography in April 2007.  They were abolished on 31 March 2013 and replaced by NHS Commissioning Regions.

Parish

Parishes are subdivisions of local authorities in many parts of England, and their councils are the most local level of government. Unlike electoral wards/divisions, however, parishes are not found in all parts of England. The Welsh and Scottish equivalents are communities. Note that the full term for administrative parishes is “civil parishes”, to distinguish them from the ecclesiastical parishes that are found in all parts of the UK.

PO BOX

If individuals or organisations prefer for their mail to be delivered to a non-identifiable postal address, they may opt to set up a PO Box. PO Box addresses do not have a specific geographic location; instead the mail is sent to a local delivery office, from where it can be forwarded to the real address or collected by the addressee.

Point

In terms of Geographic Information Systems (GIS), a point is a feature that can be defined by a single (x,y) co-ordinate pair.

Point-in-polygon

Point-in-polygon is an overlay operation used in Geographic Information Systems (GIS). It is used to determine whether a given point lies inside a given polygon (area). For example, it might be used to establish whether a particular postcode (identified by a grid reference) falls within a particular electoral ward.

Police Force Area

There are 43 police force areas in England and Wales, each covering one or more complete local authorities. Scotland has eight police force areas, each covering one or more council areas. Northern Ireland is covered by one police force.

Polygon

In terms of Geographic Information Systems (GIS), a polygon is a feature defined by a series of sequential co-ordinates that join up to make a closed shape. Examples of polygons include buildings, tracts of water and any geographic units (electoral wards, districts, health authorities etc).

Polygon-in-polygon

Polygon-in-polygon is an overlay operation used in Geographic Information Systems (GIS). It is used to determine whether a given polygon lies inside (or overlaps) another polygon. For example, it might be used to establish which Census output areas fall within a particular electoral ward.

Postcode

Postcodes are assigned by Royal Mail to identify postal delivery areas across the UK. They are also a key means of providing locational references for statistical data.
Further information on postcodes. This includes information on postcode structure, large and small user postcodes, and the use of postcodes for referencing data.

Postcode: Non-geographic

Non-geographic postcodes can either be special postcodes assigned to some large users of the postal service or PO Boxes that lie within a (pseudo) postcode district that does not form a discrete part of a postcode area.

Postcode: Terminated

Terminated postcodes are postcodes that are no longer used for mail delivery. The most frequent reasons for terminations are postcode reorganisations or the demolition/redevelopment of buildings. Terminated postcodes are occasionally re-used by Royal Mail but not before an elapsed period of 2 years. Terminated postcodes are retained in our postcode directories until or unless they are re-used.

Postcode Address File (PAF)

The Postcode Address File (PAF) is a database of all UK addresses and postcodes. It is produced by Royal Mail and is continuously updated.

Primary Care Group (PCG)

Primary care groups (PCG) were a local unit of health administration in England between 1999 and 2002, although by the end of this period many of them had converted to primary care trusts (PCT). Until the reorganisation of English health geography on 1 April 2002, PCGs/PCTs reported to health authorities (HA). Unfortunately they were defined in different ways in different parts of the country, thus providing a very inconsistent geography.

Primary Care Organisation (PCO)

Primary care organisations (PCO) were a generic term including English primary care trusts (PCT) and care trusts (CT) based on the PCT model, as well as the Welsh local health boards (LHB). It previously incorporated the former English primary care groups (PCG) and the Welsh local health groups (LHG). PCOs were abolished on 31 March 2013 and replaced by Clinical Commissioning Groups (CCG).

Primary Care Trust (PCT)

Primary care trusts (PCT) were a local unit of health administration in England. After the reorganisation of English health geography on 1 April 2002, PCTs reported to the strategic health authorities (SHAs). Further restructuring of health administration in 2006 reduced the number of PCTs significantly. The majority of PCTs were defined in terms of local authority districts, but there were some exceptions. Although most of England fell within a PCT, some areas had care trusts (CT) instead. PCTs did exist before 1 April 2002 and, together with primary care groups (PCG), reported to health authorities (HA). PCTs were abolished on 31 March 2013 and replaced by Clinical Commissioning Groups (CCG).

Prison Service Area

Prison service areas cover England and Wales. There are ten in England and one in Wales. The English prison service areas correspond with the regions (former GORs), with the exception of the South East Region, which has been split into two prison service areas.
