A wide range of organisations work in the justice sector:

• police
• prisons and other secure detention 
• probation
• criminal justice social work
• courts
• prosecution services
• voluntary sector agencies
• private sector companies

There are just under 4,000 organisations in the sector of which 78% are located in England, 11% in Scotland, 7% in Wales and 4% in Northern Ireland.  The majority of organisations are part of the community justice sub-sector.  These figures do not include non-core organisations (which are organisations outside the justice sector, but support the sector’s activities) estimated at 13,000, so may significantly underestimate the number of organisations in the sector.
