The United States of America (USA), commonly referred to as the United States (U.S.) or America, is a federal republic composed of 50 states, a federal district, five major territories and various possessions. The 48 contiguous states and Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is in the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The territories are scattered about the Pacific Ocean and the Caribbean Sea. At 3.8 million square miles (9.842 million km²) and with over 320 million people, the country is the world's third or fourth-largest by total area and the third most populous. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States are also extremely diverse, and the country is home to a wide variety of wildlife.

President of the United States

The President of the United States of America (POTUS) is the elected head of state and head of government of the United States. The president leads the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces.

The President of the United States is considered one of the world's most powerful people, leading the world's only contemporary superpower. The role includes being the commander-in-chief of the world's most expensive military with the largest nuclear arsenal and leading the largest economy by real and nominal GDP. The office of the president holds significant hard and soft power both in the United States and abroad.

Article II of the U.S. Constitution vests the executive power of the United States in the president. The power includes execution of federal law, alongside the responsibility of appointing federal executive, diplomatic, regulatory and judicial officers, and concluding treaties with foreign powers with the advice and consent of the Senate. The president is further empowered to grant federal pardons and reprieves, and to convene and adjourn either or both houses of Congress under extraordinary circumstances. The president is largely responsible for dictating the legislative agenda of the party to which the president is enrolled. The president also directs the foreign and domestic policy of the United States. Since the founding of the United States, the power of the president and the federal government has grown substantially.

U.S. state

A state of the United States of America is one of the 50 constituent political entities that shares its sovereignty with the United States federal government. Due to the shared sovereignty between each state and the federal government, Americans are citizens of both the federal republic and of the state in which they reside.State citizenship and residency are flexible and no government approval is required to move between states, except for persons covered by certain types of court orders (e.g., paroled convicts and children of divorced spouses who are sharing custody). States range in population from just under 600,000 (Wyoming) to over 38 million (California). Four—Kentucky, Massachusetts, Pennsylvania, and Virginia—use the term commonwealth rather than state in their full official names.

States are divided into counties or county-equivalents, which may be assigned some local governmental authority but are not sovereign. County or county-equivalent structure varies widely by state. State governments are allocated power by the people (of each respective state) through their individual constitutions. All are grounded in republican principles, and each provides for a government, consisting of three branches: executive, legislative, and judicial.

List of Presidents of the United States

Under the United States Constitution, the President of the United States is the head of state and head of government of the United States. As chief of the executive branch and face of the federal government as a whole, the presidency is the highest political office in the United States by influence and recognition. The president is also the commander-in-chief of the United States Armed Forces. The president is indirectly elected to a four-year term by an Electoral College (or by the House of Representatives, should the Electoral College fail to award an absolute majority of votes to any person). Since the ratification of the Twenty-second Amendment to the United States Constitution in 1951, no person may be elected president more than twice, and no one who has served more than two years of a term to which someone else was elected may be elected more than once. Upon the death, resignation, or removal from office of an incumbent president, the vice president assumes the office. The president must be at least 35 years of age, has to have lived in the United States for 14 years, and has to be a "natural born" citizen of the United States.
