Commenting on today's figures, Merrion economist Alan McQuaid said there was an average rise in the numbers at work in 2015 of 49,700, up from 32,700 in 2014.
Mr McQuaid said that based on the data up to the third quarter it looks like there was an overall jobs increase last year of 53,000.
"But the outlook from 2017 on is more uncertain in light of Brexit. Still, we expect the downward trend in unemployment to continue over the next twelve months, albeit at a slower pace than before," the economist added.
