Alphabet City is a neighborhood located within the Lower East Side and East Village in the New York City borough of Manhattan. It is also known as Loisaida^{[citation needed]}, a Spanglish adaptation of 'Lower East Side'. Its name comes from Avenues A, B, C, and D, the only avenues in Manhattan to have single-letter names. It is bordered by Houston Street to the south and by 14th Street to the north, along the traditional northern border of the East Village and south of Stuyvesant Town and Peter Cooper Village. Some famous landmarks include Tompkins Square Park and the Nuyorican Poets Cafe. The neighborhood has a long history, serving as a cultural centre and ethnic enclave for Manhattan's German, Polish, Hispanic, and Jewish populations.

Alphabet City is located in New York's 12th and 14th congressional districts, the New York State Assembly's 64th and 74th districts, the New York State Senate's 25th district, and New York City Council's 2nd district. It is represented by Congresswomen Carolyn Maloney and Nydia Velázquez, State Senator Dan Squadron, Assemblymen Sheldon Silver and Brian Kavanagh, and Councilwoman Rosie Mendez. The neighborhood is regulated by Manhattan Community Board 3. The neighborhood lies within the New York Police Department's 9th precinct, and its schools fall within Manhattan's 1st school district. If the neighborhood is considered, as according to some definitions, to extend to 23rd Street as its northern boundary, it also encompasses parts of the New York State Senate's 29th district (represented by State Senator Thomas Duane), New York City Council's 4th district (represented by Daniel Garodnick), and Manhattan Community Board 6.

Manhattan (/mænˈhætən/) is the most densely populated and the oldest of the five boroughs of New York City. Located primarily on the island of Manhattan at the mouth of the Hudson River, the boundaries of the borough are identical to those of New York County, an original county of the U.S. state of New York. The borough and county consist of Manhattan Island and several small adjacent islands: Roosevelt Island, Randall's Island, Wards Island, Governors Island, Liberty Island, part of Ellis Island,Mill Rock, and U Thant Island; as well as Marble Hill, a very small area on the mainland bordering the Bronx. The original city of New York began at the southern end of Manhattan, expanded northward, and then between 1874 and 1898, annexed land from surrounding counties.

The New York County is the most densely populated county in the United States, and one of the most densely populated areas in the world, with a 2010 population of 1,585,873 living in a land area of 22.96 square miles (59.5 km²), or 69,464 residents per square mile (26,924/km²), more dense than any individual American city. It is also one of the wealthiest counties in the United States, with a 2005 per capita income above $100,000. Manhattan is the third-largest of New York's five boroughs in population, and its smallest borough in land area.
