Yonkers: Sixth Borough (nickname)

New York City has five boroughs. The consolidation into the borough system took effect on January 1, 1898.
 
Yonkers (in Westchester County) was soon proposed to be New York’s sixth borough. Many other cities and counties and even countries have been called “New York’s sixth borough,” such as Fort Lee (NJ), Jersey City (NJ), Nassau County (NY), and Rockland County (NY).
 
Miami (South Florida) has a well-known reputation as “New York’s sixth borough.”
 
Israel and Puerto Rico have sometimes been called New York’s sixth borough.
 
An August 2005 New York Times article called Philadelphia (PA) New York’s sixth borough, although several bloggers fiercely deny that Philadelphians have called their city that.
   
     
Wikipedia: Sixth borough
The term sixth borough is used to describe any of a number of places that are not politically within the borders of any of the five boroughs of New York City that have instead been referred to as a metaphorical part of the city by virtue of their geographic location, demographic composition, special affiliation with New York City, or cosmopolitan character. They include adjacent cities and counties in the New York metropolitan area as well as in other states, U.S. territories, and foreign countries.

Historical proposals
(...)
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.

Jersey City: New York’s Sixth Borough?

Today’s City Living section highlights Hoboken, of “Pretty please can we be the sixth borough? We’re obviously a hip alternative to living in the city and we’re only 10 minutes away by PATH, we swear!” fame. I admittedly have never been to Hoboken, and though I’ve actually heard mostly positive things from those who do reside there (read: it’s cheap), no amount of poor rationalizations about how the nightlife is great and how “close to Manhattan” it is will change the fact that you’re still living in New Jersey.

Even the headline, “Philadelphia Story: The Next Borough,” has a condescending quality to it. And has any true Philadelphian ever called this city New York’s “sixth borough”?

New York’s Sixth Borough?

I live in NYC and when to Philly recently and really thought it was a nice city. But it can’t be “New York’s Sixth Borough” that belongs to Long Island which has a population of 2.8 Million, not including Queens & Brooklyn. Anyways,
Philly is a cool city.
