Projections about where the people of Wales will live in the future show a big increase in homes with several adults but no children.
Research shows 40 per cent of first-time buyers in Wales bought their first property in order to be near to their relatives.
Shelter Cymru says that tenants are having to pay 'unreasonable' administration fees, and some letting agents show a 'lack of transparency.'
A housing charity says that more needs to be done to protect vulnerable adults in private rented homes. It comes after an ITV Cymru Wales investigation into the living conditions of some vulnerable adults across the country.
Ceri Dunstan from Shelter Cymru says there needs to be a support network in place.
There are encouraging signs tonight that first-time buyers are getting a bigger slice of the housing market.
Today Wales' largest building society, the Principality, announced that they lent more than a billion pounds in mortgages last year.
That money has helped thousands of people get onto the property ladder - and in Wales, first-time buyers were getting a bigger share than ever before.
The building society Principality have announced an increase in mortgage lending of 10.7% in the last year.
First-time buyer lending has also increased, with the society helping over 1,800 first-time buyers across the UK onto the property ladder.
Principality has also grown its Welsh first-time buyer market share to a record high of 12%.

"We have...continued to support the regional economy, opening our 53rd branch on Cwmbran high street, creating a further 58 jobs across the Group and increasing residential lending in Wales by 42%."
Graeme Yorston from The Principality Building Society says first time buyers are 'critical' to Wales' housing market.
Wales' biggest building society will be announcing its annual results later. It is thought the results will be positive, led by an increase in the number of first time buyers.
The Principality, Wales' biggest building society, will announce its annual results for 2013 later this morning.
The figures are expected to be a good indicator for the Welsh economy, underlying a recovery in the housing market.
It's thought last year's positive figures are a result of more first time buyers getting on to the property ladder in Wales.
House building in Wales slowed down in the last three months of 2013, according to the latest economic survey from the Federation of Master Builders (FMB).
Following the launch of the Welsh Government's 'help to buy' scheme, it is hoped that the housing market will be revitalised, but the FMB say more needs to be done to increase supply.
Owain Llywelyn, Welsh spokesperson for the Royal Institute of Chartered Surveyors told ITV Cymru that today's figures are 'pleasing' and it shows there is an increased confidence in the construction industry across the UK.
He added Wales is beginning to witness an upsurge in this sector and the house building specifically has helped drive the recovery.
House building across Wales continued its revival towards the end of last year with the private sector leading the way, according to the latest survey by the Royal Institute of Chartered Surveyors (RICS).
Predictions for employment levels were also on the rise with 79% more chartered surveyors in Wales expecting workloads to increase rather than decrease this year.
However, the survey also revealed that there are some shortages in skills and materials, despite the recovery in the construction industry.
Neil Brierley, Chair of RICS Wales said:
_“With the Welsh economy continuing to improve in recent months, it is very welcome news that the construction industry has followed suit and activity is on the rise across the region. _
"More homes are being built, investment in infrastructure is continuing and Wales is beginning to benefit from this more positive picture."
Wales' largest house builder has announced plans to build 450 new homes across Pembrokeshire, with, it says, the potential to create over 1,300 jobs over the next five years.
Managing Director of Persimmon Homes West Wales, Huw Llewellyn, said: "We have found that the Local Authorities in West Wales have reacted more positively to the economic realities facing house builders and are taking positive steps to help make developments viable.
According to Pembrokeshire County Council's Local Development Plan, there is a significant lack of housing in the region and this latest announcement from Persimmon Homes will provide around 90 affordable houses.
The remainder will be available on the Welsh Government's Help to Buy Wales scheme thus helping first time buyers and families looking to upgrade to a bigger family home to do so.
Between now and 2021, Pembrokeshire County Council has made provision for 7,300 dwellings in the Local Development Plan, enabling the delivery of 5,700 homes, and Persimmon Homes is set to deliver eight per cent of this over the course of the next five years.
