Mortgage arrears
The Money Advice and Budgeting Services (MABS) dealt with 15,387 new clients last year, while the MABS Helpline received 26,292 calls.
The problem of mortgage arrears, though reduced in 2018, was a source of continuing concern.
Abhaile, the mortgage arrears support scheme, issued more than 10,000 vouchers for professional assistance - and dedicated mortgage arrears advisers helped 5,498 borrowers in late-stage mortgage arrears.
The National Advocacy Service for people with disabilities (NAS) provided representative advocacy to 916 people and supported 2,619 people with information, advice and other advocacy supports.
And the Sign Language Interpreting Service (SLIS) handled 6,412 interpreting assignments in 2018 - an increase of 58% over 2017.
As a result, a national recruitment campaign is now being held with 59 posts - including 23 new posts - advertised across 40 locations.
Angela Black is chief executive of the Citizens Information Board.
She said: "I am delighted to see the benefits of the CIS restructure.
"The network of services is now better aligned with new governance requirements for organisations in receipt of State funding.
"The introduction of new grades of staff will increase the number of information officer posts and introduce the senior information officer and regional administrator grades.
"As a result, overall staffing levels in the CIS will increase by 7%, with frontline staff increasing by 10.6%".
