Emerging from Helsinki's grandiose central railway station on a bitterly cold evening, it does not take long before you notice something unusual. There are no rough sleepers and no-one is begging. For the past 30 years, tackling homelessness has been a focus for successive governments in Finland. In 1987, there were more than 18,000 homeless people there. The latest figures from the end of 2017 show there were about 6,600 people classified as without a home. The vast majority are living with friends or family, or are housed in temporary accommodation. So how have the Finns managed it? Since 2007, their government has built homeless policies on the foundations of the Housing First" principle. Put simply, it gives rough sleepers or people who become homeless a stable and permanent home of their own as soon as possible. It then provides them with the help and support they need. That may be supporting someone trying to tackle an addiction, assisting them to learn new skills, or helping them get into training, education or work. Under Housing First, the offer of a home is unconditional. Even if someone is still taking drugs or abusing alcohol they still get to stay in the house or flat, so long as they are interacting with support workers. In Helsinki, deputy mayor Ms Vesikansa believes tackling homelessness and ending rough sleeping is not only a moral obligation but may also save money in the long-run. "We know already that it pays back because we have expenses elsewhere if people are homeless," [she said].
