You can clearly see that it's not just poverty and political in-stability that can increase suicide rates.
Several OECD nations with a good standard of living also have high suicide rates.
I'd heard that Japan and Finland had problems. But Belgium, Switzerland, France, and New Zealand? That came as a real shock.
For decades, New Zealand has had more people dying from suicide than from road accidents (and not because there's a low rate of road accidents - New Zealand has one of the highest road fatality rates in the world).
But by 2008, things had improved dramatically. This world map shows the suicide rate per 100,000 people in each country around the year 2008 Source
Between 1995 and 2000, New Zealand and Finland had the highest suicide rates for young men (aged between 15 and 24) in the OECD countries.
But by 2005, the figures for New Zealand had improved dramatically, as you can see here - dropping down to about halfway down the list of suicide rate per 100,000 people. Source
