Lincoln has been named one of the happiest cities in the United Kingdom as a company looked at the amount of smiles in photos.
The list was created by a company called JetPac who used their own photo app and social network, Instagram, to see how many people were smiling in photos.
They believe that a person smiling is the biggest sign of happiness; however the degree of a smile is taken into consideration. For example a grin won’t gain as high a score as someone with a wide smile. The software used looks at the amount of pixels in one persons smile.
Lincoln is the fifth happiest city with a score of 31.95, with Belfast leading the list with a score of 34.29.
JetPac looked at over 100 million pictures across 40 towns, observing several different things in the pictures.
Other than smiles, the app looked at women who wore red lipstick and men with moustaches. According to the company, these trends suggested lipstick wearing and moustache bearing humans were more outgoing and wanting to have a good time.
Salford came bottom of the 40 cities with a score of 17.90.
