The Encyclopedia of New York City, The Neighborhoods of Brooklyn and The Neighborhoods of Queens are excellent sources for boundaries.

To Alexa .. what is now Holliswood Hospital began as Terrace Heights Hospital in the '50s.

This guest was helpless and hopeless. Most of his answers were the equivalent of, "I don't know. Why are you asking me that? I am an amateur." Why have this worthless segment. You might just as well have picked out a trader on Wall Street or a Staten Island Ferry captain to be the authority.

@sheldon, I live in North Crown Heights "Historic district according to the street signs". There's a brown sign on Pacific Street claiming that it's in that district, so the City seems to think that Atlantic (one block north) is the boundary. just to toss in my nickle.

To BK from Hoboken. FYI, It's Gramercy (1 m) Park not Grammercy - a made up name for newer DBA trade names in the area. If the RE guys are dumb enough to add an m, it doesn't NYers have to accept it. Proof - 6th Avenue in Manhattan & lots of others

How does Matthew decide contentious boundaries?
Are the is it all crowd sourcing or is there historic backing and research?
No offence to Matthew, but how was he chosen for this position? Since there is no authority or regulation of neighborhood names, Google is where people go, making it a lot of power. Wouldn't a historian or urban planner be more qualified?

I live in Holliswood, Queens. Google Maps shows our neighborhood as Terrace Heights. Local residents are not familiar with that name. What is the origin of the name, Terrace Heights? As a frame of reference, Holliswood is between the Grand Central Parkway on the north, Hillside Avenue on the south, 188th Street on the west, and Francis Lewis Blvd on the East. Oddly, even many Queens residents are not familiar with Holliswood.

So right RTC, Carroll Gardens was a successful re-branding story. Will Gowanus be next?

Nina - don't forget "Victorian Flatbush"

@Berkley - 23rd and 4th should be Greenwood Heights but most people under 50 and realtors say South Slope.

This stuff evolves. I grew up in what we called Red Hook or Gowanus, on First Place between Court and Clinton Streets in Bklyn. In the mid-sixties, a friend of my parents, a real estate broker, got together with a few other brokers and renamed the area "Carroll Gardens," marketing apartments to Manhattanites. We laughed at him -- who'd want to live in our Italian, working-class neighborhood, other than us?

Undaunted, he and his friends took up a collection and planted trees along First Place. The first Manhattan, non-Italian family moved in -- they were long-haired blondes, so we called them "the beatniks." Today, the neighborhood is Carroll Gardens, officially, and none of us can afford to live there.

99 First Place, forever! (If you live there, can I please take a peek at my childhood home?)

My favorite name for the West SOHO / South Village / Hudson Sq area is "ASHO" for "Almost SOHA."

I would say Sunnyside ends at the Sunnyside train yards. LIC begins in Queens Plaza

Mr. Hyland does not seem to know NYC well enough to make these pronouncements. He does not know Windsor Terrace, downtown Manhattan or where Columbia is?

AD, I doubt this guy knows but the consensus is Classon Ave. Although as far west as St. James was once considered Bed Stuy in the 80's.

104th to 110th on the west side is sometimes known as Bloomingdale

Low 100s in Manhattan, which I think is the Upper West Side, should be renamed :
My votes are Volvo-Ho, or Park Slope North, or ParkSloNo. Or maybe just snarky ho?

Great guest. Doesn't appear to "know" any "areas" very "well."

People who try to come up with these dumb neighborhood names don't have the right to do so because none of them are native NYers.
WASTE. OF. TIME.

You guys are wrong. "Hudson Square" is a name that goes back to the turn of the last century, and there used to be a park called Hudson Square.

I live in West Midwood, Brooklyn, a subsection of Flatbush. There are many such subsections: South Midwood, Midwood Park, & Fiske Terrace. My area has been lumped with more pricey Ditmas Park. Who gives lisence to authorize these arbitrary zones?

36th street to the Prospect Expressway on the West side of the cemetery in Brooklyn is now being called Greenwood Heights. New bars and business in the neighborhood are using the name. Has some bloggers really upset.

I lived for years on 17th St between 3rd and 4th Ave in Brooklyn. Realtors loved to call it Park Slope... Ha! Hardly.

I coined it Home Depot City.

What is 23rd and 4th Avenue in Brooklyn - Park Slope, South Slope or Sunset Park?

I live in Bushwick and when I first moved to this area, realtors called it "East Williamsburg". This was 4 years ago, just as Bushwick was blossoming into what it is now. Since then, the name "Bushwick" has become a selling point. But this neighborhood was always Bushwick, to me and my neighbors and the people that have lived here for years. Is East Williamsburg an actual neighborhood or was it something that realtors invented to make Bushwick sound nicer before it became desirable?

55th and 3rd--SoBlo (south of Bloomingdales)

Around Broadway 96th-110th is the "Upper Upper West Side"

I live on 60th Street (bet Broadway & Columbus). Is is Lincoln Square? Is it Hells Kitchen? Is it Clinton? OR should it be a NEW neighborhood "Columbus Circle"...?

Columbia claims to be in Morningside Heights and no one ever disputed that.

Which street divided BedStuy from Clinton Hill? I also live on the cusp and have often heard it referred to as Bedford Hill.

Amelia, it is Washington Ave - on the east side NOT Franklin Ave, which is firmly in Crown Heights - for now.

57 the 8th Ave - should be "Clinton" the guest should know this.

we live in the demi-ghetto on West 130's in Harlem. we call it the vUWS - the Very Upper West Side b/c I have bus that's taking me right down the park.

When I met my wife, the maps in taxis had differently colored boundaries for each neighborhood. She lived on Lex between 32 and 33. It was a grey area in the taxi map with no. So she told people she lived between Murray Hill and Grammercy Park. I told she lived in the twilight zone.

Where does Dyker Heights and Bensonhurst - where do they end and begin?

I noticed there's some empty spaces on the map, like between williamsburg and bushwick- are these areas under contention?

what is the line between the upper east side and east harlem

Hahaha about Upper West Side South -- I was thinking that parts of Harlem should now be called Upper West Side North.

ELITA = East of Little Italy

So soon Park Slope is soon going to be all the way to Sheepshead Bay and Bay Ridge?

i've heard my neighborhood called bedford hill, a mashup of bed-stuy and clinton hill. it's right on the cusp, but it's more bed-stuy than clinton hill.

I feel like there is a gray area of Crown and Prospect Heights (and please don't call it Pro-Cro) I think Franklin Avenue is the dividing line, but other say Washington Avenue. How do you decide?

Do you mean Park Slop?!

To Michael B - Google is now the arbiter of EVERYTHING.

Tell this guy to get a real job and stop naming areas that are plain ol' stupid. Idiot!

wow this segment is such a "fluff downer" after the danon "apocalypse interview" - bad transition

What is the dividing line between Windsor Terrace and Kensington?

Who elected the Sillycone Shallow Googlytes to be the arbiter of NYC neighborhoods??

Hmm, Bed Stuy has historically ended a block or two south of Atlanic Ave in what is now considered part of Crown Heights, yet most people use Atlanic Ave as the cut off. What does Mr. Hyland think?

Above should read "Fresh Meadows."

I just moved to Manhattan from Queens. But Google Earth misplaces my building at mid-block, not at the NE corner of 100th St @ Columbus Avenue. I was unable to correct the marker placement on Google Earth.

The building is part of NYCHA housing & the street addresses are arbitrary & posted on the buildings so any outside system would create mistakes on most if not all NYCHA developments as well as large private developments, Fresh Meadow, Peter Cooper Village, etc.
