The Upper West Side is a neighborhood of the borough of Manhattan in New York City that lies between Central Park and the Hudson River above West 59th Street.
Like the Upper East Side, the Upper West Side is primarily a residential and shopping area, with many of its residents working in more commercial areas in Midtown and Lower Manhattan. While these distinctions were never hard-and-fast rules, and now mean little, it has the reputation of being home to New York Citys liberal cultural and artistic workers, in contrast to the Upper East Side, which is perceived to be traditionally home to more affluent conservative commercial and business types. The neighborhood is rather upscale with the median household income in many areas exceeding Manhattan average to a considerable extent.
Traditionally the neighborhood ranged from the former village of Harsenville, centered on the old Bloomingdale Road (now Broadway) and 65th Street, west to the railroad yards along the Hudson, then north to 110th Street, where the ground rises to Morningside Heights. With the building of Lincoln Center, its name, though perhaps not the reality, was stretched south to 59th Street. With the arrival of the corporate headquarters and expensive condos of the Time Warner Center at Columbus Circle, and the Riverside South apartment complex built by Donald Trump, the area from 59th Street to 65th Street is increasingly referred to as Lincoln Square by realtors who acknowledge a different tone and ambiance than that typically associated with the Upper West Side.
Originally the name Bloomingdale (from the Dutch "Bloemendaal"), or the Bloomingdale District, applied to the west side of Manhattan from about 23rd Street up to the Hollow Way (modern 125th Street), and it contained numerous farms and country residences of many of the citys well-off. The main artery of this area was the Bloomingdale Road, which began north of where Broadway and the Bowery Lane join (at modern Union Square) and wended its way northward up to about modern 116th Street in Morningside Heights, where the road further north was known as the Kingsbridge Road. Within the confines of the modern-day Upper West Side, the road passed through areas known as Harsenville, Stryckers Bay, and Bloomingdale Village.

In the eighteenth and early nineteenth century, the Upper West Side-to-be contained some of colonial New Yorks most ambitious houses, spaced along Bloomingdale Road. It became increasingly infilled with smaller, more suburban villas in the first half of the nineteenth century, and in the middle of the century, parts had become decidedly lower class.
