An analysis of terms used on Twitter has been used to rank Lima the ninth most unhappy city in the nation. The Lima News reports a University of Vermont study looked through geotagged Twitter terms and determined the majority of tweets from Lima had an unhappy tone in 2011. However the methodology of the study has been questioned by more than a few people. Bluffton University Professor Dr. Will Slater told the newspaper Twitter terms aren't exactly hard data, and that it's hard to say the sample size of people tweeting from Lima is inclusive enough of the entire population.
