The figure is growing at the highest rate in Europe.
The Union of Students in Ireland says a preference to buy rather than rent is a major factor in how long Irish children stay living at home.
A new Eurofound report shows the number of Irish people aged 25-29 living with their parents grew at one of the highest rates in Europe between 2007 and 2017.
The figure now stands at more than 47%, up by over 10% in the last decade.
USI Vice President of the Border, Midlands and Western region, Marie Lyons, says it's a disappointing trend:
