Know what your New York City home is really worth

New York, often called New York City (NYC), is the most populous city in the United States. It is located at the southern tip of New York State on New York Harbor, one of the world's largest natural harbors. The city comprises five boroughs, each coextensive with its respective county. It is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the United States by both population and urban area. New York is a global center of finance and commerce, culture, technology, entertainment and media, academics and scientific output, the arts and fashion, and, as home to the headquarters of the United Nations, international diplomacy.

With an estimated population of 8,584,629 in July 2025, distributed over 300.46 square miles (778.2 km2), New York is the most densely populated major city in the United States. New York City has more than double the population of Los Angeles, the country's second-most populous city. Over 20.1 million people live in New York City's metropolitan statistical area and 23.5 million in its combined statistical area as of 2020, both the largest in the U.S. New York City is one of the world's most populous megacities. The city and its metropolitan area serve as the premier gateway for legal immigration to the United States. An estimated 800 languages are spoken in New York City, making it the most linguistically diverse city in the world.

The island of Manhattan had been inhabited by Munsee-speaking Lenape around 1624, at the time Dutch colonists established Fort Amsterdam and a trading post on the island, the first European settlement in what would become New York City. The settlement was named New Amsterdam in 1626 and was chartered as a city in 1653. The city came under English control in 1664 and was temporarily renamed New York after King Charles II granted the lands to his brother, the Duke of York, before this name was permanently adopted in 1674. Following independence from the Kingdom of Great Britain, the city was the national capital of the United States from 1785 until 1790. The modern city was formed by the 1898 consolidation of its five boroughs: Manhattan, Brooklyn, Queens, the Bronx, and Staten Island.
