Update 5.15pm: The latest Census figures show hearly 500,000 adults are living with their parents.
"The 2016 Census figures released by the CSO today make stark reading They show that nearly half a million adults over 18 years of age are living with their parents. This is an increase of 4.4%," said Labour's Joe Costello.
"Nearly half or 215,000 were at work and a staggering 58.6% were male adults.
"The quality of life for young adult working males, in particular, has deteriorated sharply in recent years. The shortage of affordable housing and the prevalence of low paid employment is playing havoc with young people’s lives."
He went on to criticise comments made by the Taoiseach on television last night.
"Last night on the Vincent Browne Program on TV3, the new Taoiseach, Leo Varadkar, admitted that his Government would meet none of its targets on housing and homelessness during its lifetime.
"Thus, a generation of Irish youth which get up early in the morning and goes to work each day will continue to face the prospect of living with their parents and never having a place of their own.
"His further statement on the same program is even more worrying. He declared that it is belief that those working on the minimum wage which is only €9.25 per hour constitute ‘middle Ireland.’
"This is indeed cold comfort for young working adults. It demonstrates that the Taoiseach is totally ignorant or totally uncaring of what people in poorly-paid employment, compelled to live their parents experience."
Update: The CSO’s latest batch of stats from last year’s census show the number of married people is up 5% in five years, and they now make up 48% of the population.
There were 9% more separated and divorced people in 2016 than when the last census was taken in 2011.

Earlier: New analysis of the 2016 census has indicated that the population of Ireland could be larger than we think.
Geodirectory says the actual number of vacant houses is half that of the official figures - although the CSO disputes this.
The discrepancy could mean our population of 4.7 million is underestimated by as much as 150,000, given the average household size is 2.75 people.
Justin Gleeson of the All Ireland Research Observatory at NUI Maynooth says the findings are significant.
"By putting all this additional information into the reasons for the vacancy, that was the first time we got to understand why these properties were vacant," he said.
"I think the overall message here is that in the true sense, we don’t have 180,000-odd vacant properties across the country, it’s much more down around the 96-100,000 figure."
