Tennessee is the happiest state in the union

(CNN) - Where's the happiest state in the Union… according to Twitter? Tennessee tweeters are tops if a new informal study by a Cambridge University doctoral student is to be believed.

The student searched for tweets with happy words and situations, and arranged them by state and country.

She found Tennessee was the happiest state, followed by Colorado and North Carolina.

Nevada was the lowest-ranked state, although the researcher didn't have any data for Alaska, Idaho, Montana, Wyoming or the Dakotas.

Overall, the United States was the fourth happiest nation on twitter. Number one?  That goes to Germany.
