The total number of sex offenders in Northern Ireland subject to the notification requirements of the Sexual Offences Act 2003 was as follows:
Number 31 March 2007 670 31 March 2006 620 31 March 2005 544
The majority of persons who come under the notification requirements are subject to a notification period of five years or more and the annual increase largely reflects the number of new convictions.
As a breakdown of figures for sex offenders subject to the notification requirements was not recorded on an annual basis until 2005, I am not able to provide the information requested for 2002, 2003 and 2004.
