The Most Desolate Place in New York

Out of the 2217 Census Tracts that make up the five boroughs of New York City, 24 have a population of zero. Ten are parks (8 part of the NYC Parks department, one part of National Parks System, and one affiliated with the Smithsonian) that have access to the public and regular visitation. Five are active cemeteries that can also be counted on to have regular visitors. Four are working environments – the Oak Point rail yards in the Bronx, the Brooklyn Navy Yard, and two tracts that make up the Kings County Hospital Complex. One is LaGuardia Airport.

That leaves four Census Tracts one could reasonably call “desolate” – no permanent residents, no regular workers, and next to no visitors. One is really a ghost tract – Queens Tract 1622, which consists entirely of the Atlantic Ocean south of the Rockaways. It doesn’t even show up on the NYC Planning Department’s Census Fact Finder, but the Federal Census Bureau still lists it. Perhaps it was created to enumerate the population of Hog Island way back before it was destroyed about a hundred years ago, but I don’t even know if Census Tracts existed then. Regardless, since I can’t walk it I’m not counting it.

Two others consist of the series of marsh islands in Jamaica Bay. One of these tracts - Queens Tract 1072.02 - is easily accessed by the road between Broad Channel and the Joe Addabbo Bridge to Howard Beach, and houses the Jamaica Bay Wildlife Refuge offices. The other - Brooklyn Tract 702.03 - is tougher, but there’s a small slice of the tract that’s on the same island. It takes a bit of trampsing through marshland, but you can get there on foot.

That leaves one Census Tract with no population, no workers, no land connection, and which is officially off-limits to visitors to boot. This is Bronx Census Tract 5: North and South Brother Islands, located at the western edge of Long Island Sound between Riker’s Island and the coast of the Bronx. I think it's fair to call this the most desolate tract in New York City.

A couple of summers ago I took a boat with Marie Lorenz out to North Brother. It was a very enjoyable few hours of exploration and relaxation, but the main purpose for me was simply to knock off what is probably the toughest Census Tract to get to in New York City.

Still, it's not exactly the South Pole - between scientists, students, reporters, and your occasional curious urbanist, the islands probably see at least a few dozen visitors a year.

Ohhh...We're halfway there!

I always meant to update the maps a few times a year or so, but until I can do a Census Tract overlay on Google Maps or something, it's probably not going to happen. But I've made a lot more progress than the maps (which are 2 years old now) indicate. A fairly nondescript walk in Southern Brooklyn a few months ago gave me 1,109 - or 50.1%. I'll be putting up the new, updated maps by borough in the next few weeks.

Anyway, in honor of the halfway mark I give you Bon Jovi live in Tokyo.

"Greater Harlem"

A recent article came out in the NY Times with the headline "No Longer Majority Black, Harlem is in Transition." I have some problems with the general point and tone of the article, but better social commentators than I have detailed most of them (by the way, a much, much better and more straightforward article about the changing demographics of Harlem by Queens College Sociology Professor and Demographer Andrew Beveridge can be found here). As a demographic analyst though I would like to point out some facts that the Times was sloppy about at best, and disingenuous about at worst.

First though, I want to explain why the Times uses the boundaries of "Harlem" that they do - which they make no effort to explain themselves. As it turns out, they count a huge chunk of upper Manhattan, including Morningside Heights and East Harlem. There have been a few different people who have said things like "how can they say Harlem goes down to W. 106th street? How can they count Morningside Heights as part of Harlem?" or otherwise raised the regular old "what are the official boundaries of Harlem?" discussion (for the record - there are no "official" boundaries of any neighborhood in New York).

The answer is kind of boring. The reason the NY Times defines "Greater Harlem" as "river to river, and from East 96th Street and West 106th Street to West 155th Street," is because that exact area is what corresponds to the Census Bureau's Public Use Microdata Areas (PUMAs) NY03802 (West Harlem), NY03803 (Central Harlem), and NY03804 (East Harlem) - which is what the Times uses as their source for the demographic data. PUMA 03803 actually also takes in the Polo Ground houses north of 155th street as well, which the Times neglects to mention.

Don't ask me why the Census Bureau divides up the PUMAs that way. They usually roughly follow the Community Boards, but not always exactly. In this case, the slight difference is that Community Board 9 (West Harlem) starts at W. 110th street instead of W. 106th.

Now, as to why they used those three PUMAs to define Harlem? I suspect because that's the area that gave them the headline they wanted. "About 70% Black Now, Harlem is in Transition" - which is what they would have gotten if they had used just PUMA 03803 (Central Harlem), doesn't quite have the same ring to it. Even if you combine West and Central Harlem, or Central and East Harlem, the area is still majority black.

But back to the stats: a subtle thing I realized after looking through the numbers from the 2008 American Community Survey, was that whenever the Times says "black" - as in "in 2008, according to the census, the 77,000 blacks in central Harlem amounted to 62 percent of the population" they actually aren't using the numbers for the black population at all - they're using the numbers for the non-Hispanic, non-multiracial black population. So if you're a black Puerto Rican, or if mom's African-American and your dad's Dominican, or Irish, or Chinese, you aren't counted as "black" in the Times article. And this Hispanic and multiracial black population is fairly significant - about 10,000 people in Central Harlem, or about 8% of the population.

Now, this isn't necessarily the wrong number to use. The article specifically focuses on the rise and fall of the Southern, Great Migration-era African-American population in Harlem, and the article makes an effort to discount African and Caribbean blacks from the totals as well - although it does show a serious ignorance of Harlem's history which has long had both an Anglophone and Hispanic Caribbean black population. But what makes it a disingenuous statistic are two things:

1) The article specifically says "non-Hispanic white," when talking about the white population and doesn't say "non-Hispanic black" when talking about the black population.

2) Hispanics have only been separately enumerated since 1980, and multiracial individuals since 2000. So all of the numbers the Times uses when referencing the black population up to and including its peak in 1970 were counting black Hispanics, and all of the numbers afterward were not. All the numbers up to 1990 were counting multiracial individuals who primarily identified as black, and all the numbers afterward were not. This artificially exaggerates the decline in the black population.

This is just one concrete example of the larger issue - the Times' purposeful picking and choosing of statistics in order advance the narrative that the decline in black population is more significant than it is. You have to wait until halfway through the article before they tell you that in the "Greater Harlem" area they're talking about, blacks never made up even as much as 2/3 of the population (and that includes multiracial and Hispanic blacks). Not that this would be a terribly significant piece of news, except when coupled with the realization that the article is completely designed to overemphasize the decline of the proportion of Harlem's black population.

In fact "Greater Harlem" was barely majority black (about 52%) way back in 1990 - which is probably under 50% if you coun't people who would have identified as multiracial if they could. But of course "As Black Percentage of Population Declines by 11% at Most Over 18 Years, Harlem is in Transition," sounds really awkward.
