On 1 November 2001, the total number of prisoners in all prisons was 3,177 and total prison staff, including management, trades, industrial and medical staff, was 3,143. The ratio of prisoners to prison staff on that date was, therefore, 1.01:1. This is an overall ratio and individual ratios vary from prison to prison.
Details on average prisoner to prison staff ratios in prison services in the European Union are contained in the following table which has been extracted from the Council of Europe Annual Penal Statistics – SPACE 1, "Populations of Penal Institutions"– Survey 2000 issued in January this year. The table shows statistics for 1 September 2000, the most recent date available. It should be noted that the Council of Europe statistics, including those for Ireland, relate to custodial staff excluding management staff.
