Economic growth, democratization and rising social tolerance have all contributed to rising happiness, with democratization and rising tolerance having even more impact than economic growth. All of these changes have contributed to providing people with a wider range of choice in how to live their lives - which is a key factor in happiness.

Not surprising perhaps, then, is this:

The results indicate that Denmark is the happiest nation in the world and Zimbabwe the unhappiest.
