Central Park is the most visited urban park in the United States[15] and one of the most visited tourist attractions worldwide,[16] with 42 million visitors in 2016.[17] The number of unique visitors is much lower; a Central Park Conservancy report conducted in 2011[update] found that between eight and nine million people visited Central Park, with 37 to 38 million visits between them.[18] By comparison, there were 25 million visitors in 2009,[4] and 12.3 million in 1973.[20]
