About 128,000 children in the UK are homeless or living in temporary shelters, and the number is higher than that since the 2007-08 financial crisis.
The data put out by housing charity Shelter estimates that about 140 families become homeless every day.
The study also shows that many of these children have to share a single room with their entire family.
While the number of homeless children in temporary accommodation showed a decline between 2007 and 2011, to about 80,000, it rose steeply since then to the current level, the data shows.
It was in 2011 that the government cut the housing benefit it paid to the poor from the bottom 50% of local rents to bottom 30% of those.
The charity that calls it “a national scandal” also cite rollout of universal credit, the bedroom tax and the lowering of benefit caps in 2013 and 2016 as other factors that led to the situation.
