More than 100 life sentence prisoners are under supervision in the community after being released from prison.
In total, over 8,900 men and nearly 1,400 women are being managed by the Probation Service - with 37% of the people being monitored based in the east of the country.
Some people are working in charity shops, public areas or sports facilities after being released from prison, while other high-risk offenders are more closely monitored.
In total, 105 life sentence prisoners are on supervision in the community.
Fiona Ní Chinneide from the Irish Penal Reform Trust doesn't believe people should automatically be jailed forever if they get a life sentence.
She said: "By definition, somebody receives a life sentence because they've committed among the most grave offences.
"But there are many other considerations, including safety within the prison system and for people to have hope and be working positively towards eventual release, which might be decades later.
"Certainly it's better for the person themselves and for the prison environment."
The Probation Service has 35 community-based offices across the country, and it also has staff based in Ireland's 12 prisons.
