United States — Country Guide
Overview
The United States of America is a large federal republic in North America comprising 50 states, a federal capital district, and several territories. It is one of the world's largest countries by land area and among its most populous, with a highly diverse population shaped by centuries of immigration. The capital is Washington, D.C.
Geography
The country spans the North American continent from the Atlantic Ocean to the Pacific Ocean. Its landscapes are exceptionally varied: the Rocky Mountains and Appalachian Mountains, the Great Plains, deserts of the Southwest, the Great Lakes along the northern border, and long coastlines on three sides. Alaska (in the far northwest) and Hawaii (a Pacific archipelago) are the two non-contiguous states.
Culture
American culture is diverse and regionally varied, shaped by immigration from around the world. English is the dominant language of daily life, business and government, and Spanish is widely spoken. The country's film, music, technology and sports industries have global influence. Regional identities — from New England to the South, the Midwest to the West Coast — remain strong.
Languages
English is the dominant language used in government, education, business and daily life. Spanish is the second most widely spoken language. Many other languages are spoken in immigrant communities, and numerous Native American languages survive, some with active revitalization efforts.
Travel
The United States is a major travel destination known for its national parks, major cities and varied landscapes. Entry requirements — including visas and electronic travel authorization — depend on the traveller's nationality and change over time; visitors should always check current requirements with official U.S. government sources before booking travel.
Government
The United States is a federal presidential republic. The president serves as both head of state and head of government. Legislative power rests with Congress, which has two chambers: the Senate and the House of Representatives. Each of the 50 states has its own government with significant powers over areas such as education and policing.
Education
Education is primarily managed at the state and local level. Children typically attend elementary, middle and high school (often described as K–12), with public schooling free at the point of use. Higher education includes public state universities, private universities and community colleges offering two-year programs.
Major cities
New York City is the country's most populous city and a global center of finance and culture. Other major cities include Los Angeles, Chicago and Houston. Washington, D.C. is the national capital and seat of the federal government.
Currency
The currency is the United States dollar (USD), denoted by the symbol $. It is divided into 100 cents. The dollar is also widely used internationally as a reserve and trade currency.
Time zones
The 50 states span six standard time zones: Eastern, Central, Mountain, Pacific, Alaska, and Hawaii-Aleutian. Most of the country observes daylight saving time in the warmer months; Arizona (with limited exceptions) and Hawaii do not.
Useful facts
The country has 50 states — reflected in the 50 stars on the national flag. Independence from Britain was declared in 1776. The United States operates under a written constitution adopted in the late 18th century.
