How happy is the world?

The global twitter 'happiness index' reveals our emotional state.

Some 50 million tweets from around the world are collected each day and analysed for 'happy', 'sad' and 'neutral' word content.

Words are assigned scores with the happiest and most positive placed at the top of a 1-9 scale.

From this, an average happiness rating is calculated and plotted.

"Reporters, policymakers, academics - anyone - can come to the site and see population-level responses to major events," said Dr Chris Danforth, from the University of Vermont, one of two US mathematicians who developed the hedonometer.

The team hit the headlines in February after revealing Napa, in the heart of California's wine-growing region, to be the happiest city in the US.
