The Government statistics show that, across Britain, almost 85,000 children face waking up homeless on Christmas Day.
Shelter has launched an emergency fundraising appeal to support its work with homeless children this Christmas.
With the majority living in just one room, two-thirds of the families had such limited space they were forced to eat while sitting on the floor or bed. More than half had to share a bathroom or toilet with strangers, many of them with more than seven people, and most felt unsafe in their temporary home.
Campbell Robb, Shelter's chief executive said: "These new figures are even worse than we expected.
"We'll be there to help make sure families get the support they need to get back on their feet, but we urgently need more support so that we can be there for these families."
