The number of people signing on the Live Register showed a monthly decrease of 700, or 0.4%, in April, new figures from the Central Statistics Office show.
This brings the seasonally adjusted total to 194,700.
The CSO said the number of people on the Live Register in April is the lowest number recorded in the seasonally adjusted series since February 2008.
CSO figures released earlier this month showed that the country's unemployment rate remained at an 11-year low of 5.4% in April.
The Live Register is not designed to measure unemployment as it includes part-time workers - those who work up to three days a week - as well as seasonal and casual workers entitled to Jobseeker's Benefit (JB) or Jobseeker's Allowance (JA).
According to today's figures, long-term claimants made up less than 40% of all those on the Live Register, while just over 10% were aged under 25.
They also show that the number of men signing on the Live Register fell 16% to 107,765 in the year to April, while the number of women decreased by 10.4% to stand at 85,353.
