Depaul also said 14 babies were born into its services.
Homeless charity Depaul has said it recorded a two-fold increase in the number of men, women and children it helped last year.
According to its 2022 annual report, Depaul helped over 7,400 facing homelessness in 2022, over 1,600 of them were children.
The charity also said 763 families came through Depaul's services last year.
Depaul also said 14 babies were born into its services.
It said one in four users of its service were drug users and it saved the lives of 202 people by administering a medicine that rapidly reverses an opioid overdose.
It said the figures highlight the urgent need to address the issue of intergenerational homelessness.
Around 40% of those seeking help from Depaul were aged 18-30, with many coming directly from the care system, emphasising the need for early intervention, it said.
