11,632 people were registered as homeless over Christmas - including over 3,400 children.
It's a new record for the third month in a row.
Today's figure for December means every month in 2022 saw an increase in emergency accommodation.
The total is 30% higher than a year previous, while there was a 40 percent jump in the number of children growing up in B&Bs and Hotels.
There are over 8,300 homeless in Dublin, including more than 2,500 children
The state's figure does not include hidden homeless, rough sleepers, women in refuge centres, refugees or asylum seekers.
It’s the first time that the figures have gone up every month in a calendar year.
Catherine Kenny, CEO of Dublin Simon Community says: "We are deeply frustrated by the increase in the number of people in Dublin emergency accommodation recorded in the December 2022 Homeless Report. This is highly unusual and concerning for December, which normally features a brief decline in numbers as people are accommodated by family and friends over the Christmas period. This is the eighth month in a row in which we have broken a shocking and dismal record.
"In our capital city alone at least 2,700 households became homeless for the first time in 2022. That’s 52 households per week, or 7 households per day who lost the roof over their heads. This equates to 5 single adults and 2 families becoming homeless every day in 2022.
"While 7 households entered homelessness on a daily basis, only two households exited to a home. More and more people are becoming trapped in a system backlog that is straining under immense pressure, and the prospect of a home is moving further and further out of reach."
There are 11,632 people living in emergency homeless accommodation.
📌This is the 6th month of record-breaking figures & the 12th consecutive month of increasing homelessness.
📌Also the first time in 6 years (2016) seeing an increase over the Christmas period.@DeptHousingIRL pic.twitter.com/XLrCtg5gOH
