Sixth borough

Historical proposals

The Westchester County cities of Yonkers and Mount Vernon directly border the northern part of the Bronx and share much of that borough's heavily urbanized character. In 1894, the voters of Yonkers and Mount Vernon, along with voters in other parts of southern Westchester, took part in a referendum to determine if they wanted to become part of New York City, along with the voters in Kings, Queens and Richmond Counties (today's Brooklyn, Queens, and Staten Island, respectively). At that time, the city consisted only of Manhattan and a portion of the present-day Bronx, which had been part of Westchester until it became part of New York City in 1874. While the results of the 1894 vote were positive elsewhere, including in several other adjacent sections of Westchester, which were then annexed to the city and which thus became part of the new borough of the Bronx, the returns were so negative in Yonkers and Mount Vernon that those two areas were not included in the consolidated city and remained independent municipalities. A subway connection was planned between Getty Square in downtown Yonkers and the New York City Subway, but the project was abandoned after the failed merger vote. Local residents frequently refer to the area as "the sixth borough", referring to the two cities' location bordering the Bronx, the high number of local residents employed in Manhattan, and the area's similarly urban character.

In 1934, a bill, submitted by a New York City alderman Elias H. Jacobs, proposed merging Yonkers into New York City as a sixth borough. Joseph F. Loehr, then Mayor of Yonkers, was opposed to the merger, despite Jacobs' argument that such a maneuver would cause a rise in real estate prices and increase quality of transit.

Hudson Waterfront

New Jersey's Hudson Waterfront lies opposite Manhattan on the Hudson River, and during the Dutch colonial era, was under the jurisdiction of New Amsterdam and known as Bergen. Jersey City and Hoboken in Hudson County are sometimes referred to as the sixth borough, given their proximity and connections by PATH trains. Fort Lee, in Bergen County, opposite Upper Manhattan and connected by the George Washington Bridge, has also been called the sixth borough. In the 1920s, soon after the creation of the Port Authority of New York and New Jersey there were calls to integrate the rail and subway system in New York and Northern New Jersey by expanding the New York City Subway. After Mayor Bloomberg called for the 7 Subway Extension to continue to Secaucus Junction, a feasibility study was conducted and released in April 2013.

Waterways

In 2011, New York Mayor Michael Bloomberg referred to the city's waterfront and waterways as a composite sixth borough during presentations of planned rehabilitation projects along the city's shoreline, including Governor's Island in the Upper New York Bay. Other individuals have also referred to the city's waterways as a sixth borough.

A 2011 proposal by Vishaan Chakrabarti, a professor at Columbia University's Center for Urban Real Estate, suggested using land fill to connect lower Manhattan and Governors Island, so creating a new neighborhood referred to as "LoLo". Land fill has been used to expand Manhattan before, most notably in the creation of Battery Park City, which utilized material from the construction of the original World Trade Center. Chakrabarti and others have pointed out challenges to the proposal, which include cost, the strict regulations surrounding building with land fill, and the potential environmental effects of the project. The proposal was revisited in 2015 by author Jon Methven of The Awl, in which he referred to the proposed borough as "Frankenborough".

Outside New York metro area

Places outside of the New York metropolitan area that are home to large populations of former New Yorkers have also been referred to as the "sixth borough", including Philadelphia; Miami, and South Florida in general; Los Angeles; and, outside the continental U.S., Puerto Rico and Israel. Among those places referred to as a sixth borough are locations as diverse as Riker's Island; Philadelphia; Beverly Hills, California; Nashville, Tennessee; and China.

Philadelphia

Philadelphia has frequently been cited as a "sixth borough" due to its proximity to New York and the movement of New York residents to Philadelphia for various reasons, including lower rent prices and generally lower cost of living. The nickname has been met with apprehension by both Philadelphia and New York publications. Some have even disputed inaccurate reporting about Philadelphia by New York-based reporters.

China

Foreign countries, such as China, have also been referred to as a "sixth borough." In China's instance, it is referred to as the "sixth borough" by some media because many Chinese companies invest in developments in Brooklyn, such as Pacific Park.

Other uses

Manhattan College, located in Riverdale, Bronx, refers to its Jaspers student cheering section as "The 6th Borough" at home basketball games played in Draddy Gymnasium. In addition, the University of Connecticut (UConn) has often promoted its Huskies sports teams, especially in men's basketball, as "the Sixth Borough", given the dominance of that team in games played at Madison Square Garden. UConn also sells a T-shirt making this claim.

Jonathan Safran Foer published a short story about a fictional sixth borough, an island that gradually eroded. The story was featured in his novel Extremely Loud and Incredibly Close.
