New figures show that the number of people signing on the Live Register fell by another 2.1% to stand at 219,300 in June - the lowest figure in a decade.
The Central Statistics Office said the number of people on the Live Register - in unadjusted terms - fell by 15% to 228,075 on the same time last year.
The Live Register is not designed to measure unemployment as it includes part-time workers (those who work up to three days a week), and seasonal and casual workers entitled to jobseeker's benefit or jobseeker's allowance.
Today's figures show that on a seasonally adjusted basis the number of men signing on in June fell by 2.5%, while the number of women was down 1.7%.
They also show that the number of long term claimants in June stood at 94,778, a fall of 17.7% on the same month last year.
Meanwhile, in the year to June the number of people under the age of 25 on the Live Register fell by almost 20%.
The CSO said that annual decreases in youth unemployment have now occurred in all months since July 2010.
Earlier this week, the CSO said the unemployment rate fell to 5.1% in June from 5.2% in May - the lowest level since October 2007.
The CSO said the seasonally adjusted number of people who were unemployed stood at 120,200 in June, a decrease of 34,300 on the same time last year.
