16) Mexico
While it doesn’t have a large portion of the social projects or progressed financial status as different nations on this list, Mexico’s residents are in any case monstrously happy and always smiling in their day in day out activities. This interesting nation, one that has a rich history going back thousands years, is home to one of the biggest and happiest urban communities on the planet (Mexico City), and the biggest Spanish talking populace on the planet at 121 million. You really need to meet a Mexican to understand how they take life so simple and party large. They don’t mind working for 6 months and spend the rest of the year smiling and having fun.
