Lone parents and their children account for 53% of all homeless families in Ireland.
A new report published by the ESRI has found lone parents are much more likely to experience poor housing than any other group.
The report jointly commissioned by the Irish Human Rights and Equality Commission says the overcrowding is an issue among ethnic minorites.
Co-Author of the report Helen Russell said Eastern Europeans are in danger of becoming "left behind".
The report also found the risk of homelessness in general could rise, as Covid-19 benefits ease.
Helen Russell says the shift to to the "private rented sector rather than social housing" has brought security issues for many on the cusp of becoming homeless.
