Claremont is known as the home of the Claremont Colleges and other educational institutions, and for its tree-lined streets with numerous historic buildings. In July 2007, it was rated by CNN/Money magazine as the fifth best place to live in the United States, and was the highest rated place in California on the list. It was also named the best suburb in the West by Sunset Magazine in 2016, which described it as a "small city that blends worldly sophistication with small-town appeal." In 2018, Niche rated Claremont as the 17th best place to live in the Los Angeles area out of 658 communities it evaluated, based on crime, cost of living, job opportunities, and local amenities. Due to its large number of trees and residents with doctoral degrees, as well as its proximity to the renowned Claremont Colleges, it is sometimes referred to as "The City of Trees and PhDs."
