Here's how Finland solved its homelessness problem

The Finns have turned the traditional approach to homelessness on its head. There are a number of reasons as to why someone ends up homeless. Most homelessness policies work on the premise that the homeless person has to sort those problems out first before they can get permanent accommodation. Finland does the opposite - it gives them a home first. The scheme, introduced in 2007, is called Housing First. It is built on the principle that having a permanent home can make solving health and social problems much easier.
