Did you know that Facebook has developed an Index of Happiness? They call it GNH, Gross National Happiness, and it measures the well-being, happiness and satisfaction of the people of a nation.
Every day, we analyze all the status updates of the millions of users on Facebook . With these updates, users in a few words describe the events of the week, day or time. Put together, these updates are indicators of how the community "feels" collectively.
There will be of good days where users will use the terms positive and unhappy days with sad and negative terms. On page http://apps.facebook.com/gnh_index/?c=US you can see the graph of GNH in USA.
The graph contains several metrics. The first, GNH, represents our measure of Gross National Happiness. The other two, Positivity and Negativity, represent the two components of GNH: The extent to which words used on that day were positive and negative. Gross National Happiness is the difference between the positivity and negativity scores, though they are interesting to view on their own.
The graph is available for each country and is a great tool for statistics and research. Good reference.
