Queens is the easternmost and largest in area of the five boroughs of New York City.
 It is geographically adjacent to the borough of Brooklyn at the southwestern end of Long Island, and to Nassau County farther east on Long Island; in addition, Queens shares water borders with the boroughs of Manhattan and the Bronx.
 Coterminous with Queens County since 1899, the borough of Queens is the second-largest in population (after Brooklyn), with a census-estimated 2,333,054 residents in 2016, approximately 48% of them foreign-born.
 Queens County also is the second-most populous county in the U.S. state of New York, behind the neighboring borough of Brooklyn, which is coterminous with Kings County.
 Queens is the fourth-most densely populated county among New York City's boroughs, as well as in the United States.
 If each of New York City's boroughs were an independent city, Queens also would be the nation's fourth most populous, after Los Angeles, Chicago, and Brooklyn.
 Queens is the most ethnically diverse urban area in the world.
Manhattan ( , ) is the most densely populated borough of New York City, its economic and administrative center, and its historical birthplace.
 Locally it is often referred to simply as "The City".
 The borough is coextensive with New York County, founded on November 1, 1683, as one of the original counties of the U.S. state of New York.
 The borough consists mostly of Manhattan Island, bounded by the Hudson, East, and Harlem rivers; several small adjacent islands; and Marble Hill, a small neighborhood now on the U.S. mainland, physically connected to the Bronx and separated from the rest of Manhattan by the Harlem River.
American Copper Buildings (originally known as 626 First Avenue) is a dual-tower residential skyscraper in the Murray Hill neighborhood of New York City, in Manhattan.
 The building is being developed by JDS Development and was designed by SHoP Architects.
 The building is one of several major collaborations between JDS and SHoP; others include 111 West 57th Street, also in Manhattan, and 9 DeKalb Avenue, in Brooklyn.
111 Murray Street (formerly known as 101 Murray Street or 101 Tribeca) is a residential skyscraper under construction developed by Witkoff Group and Fisher Brothers in Tribeca, Manhattan, New York City.
Manhattanization is a neologism coined to describe the construction of many tall or densely situated buildings, which transforms the appearance and character of a city to resemble Manhattan, a heavily and densely populated borough of New York City.
 It was a pejorative word used by critics of the highrise buildings built in San Francisco during the 1960s and 1970s, who claimed the skyscrapers would block views of the bay and the surrounding hills.
 With careful urban planning, the phenomenon became more accepted in time.
 The term also gained usage as a buzzword for high-density developments in Las Vegas, Nevada, Los Angeles, Dubai, and Miami in the early 2000s and again in the 2010s.
 Another example is the construction boom in Toronto since 2007.
 The term has even been applied to many smaller US cities that have seen a large spike in downtown high rise rental buildings since the year 2000.
 Nonetheless, these cities would have to multiply their populations many times over to match the population density of Manhattan, though this is a biased comparison between a city and a district, as even the other four "outer boroughs" of New York City would have to nearly triple in population to match Manhattan's current density.
 Likewise, the just over 1 sqmi Brickell (Miami) financial district is more dense than New York City overall.
The Bronx ( ) is the northernmost of the five boroughs of New York City, within the U.S. state of New York.
 It is geographically south of Westchester County; north and east of the island and borough of Manhattan to the south and west across the Harlem River; and north of the borough of Queens, across the East River.
 Of the five boroughs, the Bronx is the only one that has the majority of its area on the U.S. mainland and, with a land area of 42 sqmi and a population of 1,455,720 in 2016, has the fourth-largest land area, the fourth-highest population, and the third-highest population density.
 Since 1914, the Bronx has had the same boundaries as Bronx County, a county of New York and the third most densely populated county in the United States.
The Orion is a skyscraper located at 350 West 42nd Street between Eighth and Ninth Avenues in the Hell's Kitchen or Clinton neighborhood of Manhattan, New York City.
 The building rises 604 feet (184 m) above street level, containing 58 floors of residential units.
 Despite its relatively modest height for a skyscraper, the residential building has dominated the 42nd Street landscape west of Times Square since its topout in September 2005, and the building has views of New York City in every direction.
One Manhattan Square (also known as 227 Cherry Street or 250 South Street) is a residential skyscraper project being developed by Extell Development Company in Two Bridges, Manhattan, New York City.
 The project is being built on the site of a former Pathmark grocery store, which was demolished in 2014.
 The building will stand 80 stories or 850 feet (259 m) above the street, and will possibly have a new supermarket in the tower's base.
 Once completed, the building will stand out significantly within the context of the neighborhood, the next highest structure being the Manhattan Bridge at roughy 30 stories (102 m) in height.
 A 13-story affordable housing component will be located separately on-site from the main tower, and completion is currently expected in 2019.
Brooklyn ( ) is the most populous borough of New York City, with a Census-estimated 2,629,150 residents in 2016.
 It borders the borough of Queens at the southwestern end of Long Island, and has several bridge connections to the nearby boroughs of Staten Island and Manhattan.
 Since 1896, Brooklyn has had the same boundaries as Kings County, the most populous county in the U.S. state of New York and the second-most densely populated county in the United States, after the county of New York (which is coextensive with the borough of Manhattan).
Iztacalco (   ) is one of the 16 "delegaciones" (boroughs) into which Mexico's Federal District is divided.
 It is located in the center-east of the district and is the smallest of the city’s boroughs.
 The area’s history began in 1309 when the island of Iztacalco, in what was Lake Texcoco, was settled in 1309 by the Mexica who would later found Tenochtitlan, according to the Codex Xolotl.
 The island community would remain small and isolated through the colonial period, but drainage projects in the Valley of Mexico dried up the lake around it.
 The area was transformed into a maze of small communities, artificial islands called chinampas and solid farmland divided by canals up until the first half of the 20th century.
 Politically, the area has been reorganized several times, with the modern borough coming into existence in 1929.
 Today, all of the canals and farmland are dried out and urbanized as the most densely populated borough and the second most industrialized.
