Demography of the United States The United States is estimated to have a population of 323,127,513 as of July 1, 2016, making it the third most populous country in the world.[2] It is very urbanized, with 81% residing in cities and suburbs as of 2014 (the worldwide urban rate is 54%).[3] California and Texas are the most populous states, as the mean center of U.S. population has consistently shifted westward and southward.[4][5] New York City is the most populous city in the United States.[6]
New York (state) The state's most populous city, New York City, makes up over 40% of the state's population. Two-thirds of the state's population lives in the New York metropolitan area, and nearly 40% lives on Long Island.[9] The state and city were both named for the 17th century Duke of York, the future King James II of England. With an estimated population of 8.55 million in 2015,[9] New York City is the most populous city in the United States and the premier gateway for legal immigration to the United States.[10][11][12] The New York metropolitan area is one of the most populous in the world.[13][14] New York City is a global city,[15] home to the United Nations Headquarters[16] and has been described as the cultural, financial and media capital[17][18] of the world,[19][20][21] as well as the world's most economically powerful city.[22][21][23] The next four most populous cities in the state are Buffalo, Rochester, Yonkers, and Syracuse, while the state capital is Albany.
World population According to current projections, the global population will reach eight billion by 2024, and will likely reach around nine billion by 2042. Alternative scenarios for 2050 range from a low of 7.4 billion to a high of more than 10.6 billion.[63] Projected figures vary depending on underlying statistical assumptions and the variables used in projection calculations, especially the fertility variable. Long-range predictions to 2150 range from a population decline to 3.2 billion in the "low scenario", to "high scenarios" of 24.8 billion.[63] One extreme scenario predicted a massive increase to 256 billion by 2150, assuming the global fertility rate remained at its 1995 level of 3.04 children per woman; however, by 2010 the global fertility rate had declined to 2.52.[64][65]
