The prison population here is growing - up almost 13% according to the last reported figures - there's also been a sharp increase of 11 % in the number of people being held on remand - the highest level it has been over the last eight years.
Why are these figures rising? And what are the main reasons people end up in prison? Is it evidence of a more violent society? Is poor education a factor? And what about mental health? - is that a key contributor?

Presenter Audrey Carville in conversation with the most recent Prisoner Ombudsman the Reverend Dr Lesley Carroll, the former Justice Minister David Ford and Father Stephen McBrearty, a prison chaplain for almost 30 years.
