At least 2,096 people in Wales have been on a housing waiting list for over ten years, figures published by the Welsh Liberal Democrats have revealed.
The figures, which were uncovered via Freedom of Information requests, also show that a staggering 8,596 people have been waiting over five years for a house.
Cardiff Council had the highest number of applicants waiting over five years or over, with 1,297 people waiting over that time.
Caerphilly Council, with 375 applicants waiting over ten years, had the highest number of people waiting over a decade.
Peter Black AM, the Welsh Liberal Democrat Shadow Housing Minister, said:
"These figures are a stark reminder just how bad the housing shortage is here in Wales. Fifteen years of Welsh Labour in Government has led to literally thousands of people waiting over a decade for a home.
"It is simply unacceptable that so many people here in Wales have had to put their life on hold until a home is available to them.
"Due to major failings with our NHS and our schools, it often goes unnoticed quite how badly Labour has let people down with regards to housing. Over a decade of inaction has led to an acute housing shortage.

Peter Black added:
"For too long the Welsh Labour Government has taken a haphazard approach to housing targets. The Welsh Liberal Democrats believe the Government's Housing Act should have included a statutory duty for Government Ministers to set termly targets for the supply of new affordable homes. After each Assembly election, a new target must be set, with a duty to review it and report back annually. This issue is so important that these targets should be enshrined in law.
"Many of us are aware of derelict and empty homes in or near our neighbourhood. Not only are they a blight on our communities, but they also, frankly, are a waste of living space. It's time the Welsh Government developed an empty homes strategy so we can finally put these buildings back into use."
