The United States of America (USA), commonly known as the United States (U.S. or US) or America, is a country comprising 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world’s third or fourth largest country by total area and is slightly smaller than the entire continent of Europe. With a population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the most populous city is New York City. Most of the country is located contiguously in North America between Canada and Mexico.
The United States is a federal republic and a representative democracy. It is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States (OAS), and other international organizations. It is a highly developed country, with the world’s largest economy by nominal GDP and second-largest economy by PPP, accounting for approximately a quarter of global GDP. The United States is the world’s largest importer and the second-largest exporter of goods, by value. Its population is 4% of the world total, but the U.S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country.
American public education is operated by state and local governments, regulated by the United States Department of Education through restrictions on federal grants. In most states, children are required to attend school from the age of six or seven (generally, kindergarten or first grade) until they turn 18 (generally bringing them through twelfth grade, the end of high school); some states allow students to leave school at 16 or 17. Of Americans 25 and older, 84.6% graduated from high school, 52.6% attended some college, 27.2% earned a bachelor’s degree, and 9.6% earned graduate degrees. The basic literacy rate is approximately 99%.
