Areas where people rate themselves the happiest also tend to have the highest suicide rates. For instance, Finland and Sweden rank sixth and seventh in the world in terms of life satisfaction, but they also have more suicides per 100,000 people than all but about 20 countries. Researchers think that this might be because people who are considering suicide in countries where people are generally satisfied with their lives see their situation as being worse than it is because they compare their lives to those of the happy people around them.
