Millennials are happier in large cities than any other generation.

Millennials are happier in large cities than any other generation. Usually, happiness rises as population decreases—but not for those born between 1992 and 2004. The young demo reports being the least happy in areas with fewer than 8,000 residents and the happiest in major metropolitan areas that over 618,000 people call home. While settling down in the suburbs used to be a sign of success, moving to the big city shows you’re “making it” today. (CityLab)
