A total of 134 families became homeless in Dublin in January, according to Focus Ireland.
The figure of 134 homeless families – which includes 269 children – is an increase of 148% on the figure of 12 months previously and is the highest ever monthly increase in family homelessness.
The previous highest monthly was 84 families in August 2015.
Of the 134 families, 125 (with 253 children) were categorised as “newly” homeless by the Dublin Region Homeless Executive, meaning they had not been homeless during the previous two years.
The other nine families had been homeless at some point in the last two years, and returned to emergency accommodation in January after their new accommodation proved unsustainable.
The organisation has said that ending the homeless crisis must be a top priority for the next government.
Focus Ireland has called on the next Government to set a firm target date for ending family homelessness and to commit to building 40,000 social homes over the next five years.
