3. Grenada
Suicide rate per 100,000 residents: 0.4
The first country to have a suicide rate of less than 1 per hundred thousand is Grenada — yet another nation from the Caribbean. The entire country’s population is a tad over a hundred thousand, and it is one of the smallest countries to be featured on our list. Despite the fact that the entire country’s population is effectively less than the number of people living in a modern city, the suicide rate is really remarkable.
