On November 29, 1984 the gay enclave of West Hollywood joined neighboring Beverly Hills as an independent city. Like Beverly Hills, West Hollywood is completely surrounded by the city of Los Angeles. Its population of 35,000 is down slightly from its peak in the 1990s. This is comparable to the population of Beverly Hills as well as New York City's West Village zip code of 10014 (the three zip codes of Greenwich Village/SoHo have a population of approximately 82,000 residents.)
This gay-flavored city also has the distinction of having a majority gay city council. Besides being a gay mecca West Hollywood is also famous for having within its borders the Sunset Strip, the Pacific Design Center, the Chateau Marmont Hotel (far left), Melrose Avenue and Santa Monica Boulevard (home to more than ten bars and clubs). And although the Beverly Center mall is just south of the city it merits honorary mention. Finally, WeHo is the place Angelenos gather to celebrate Gay Pride Day and Halloween.
Although they may not have as high a concentration of gays as West Hollywood, quite a few LA neighborhoods have a healthy representation of gay men and lesbians. The first that comes to mind is Silver Lake, situated about six miles east of WeHo. It has a few thousand fewer residents than West Hollywood.
