United States facts for kids: history, parks and landmarks

The United States is a large country in North America with about 342 million people.[1] It stretches from the Atlantic Ocean to the Pacific Ocean and includes Alaska and Hawaii. Its story includes the Declaration of Independence, the world’s first national park and the first people to walk on the Moon. This guide covers the five topics students ask about most.

History and independence

Native American peoples lived across North America for thousands of years before Europeans arrived, and many Native nations live in the United States today. In the 1600s and 1700s, Britain set up colonies along the Atlantic coast. In 1776 leaders of the colonies adopted the Declaration of Independence in Philadelphia, in the building we now call Independence Hall.[3]

The Declaration says that all people are created equal and have rights to "Life, Liberty and the pursuit of Happiness."[2] The National Archives keeps the original document, and its back is labeled "Original Declaration of Independence dated 4th. July 1776."[2] Thomas Jefferson’s writing of the first part was influenced by the Virginia Declaration of Rights.[2]

Eleven years later, in 1787, the U.S. Constitution was written and signed in the same building in Philadelphia.[3] The Constitution still sets the rules for how the national government works. UNESCO calls Independence Hall a place whose ideas of freedom and democracy influenced lawmakers around the world, and it is a World Heritage site.[3]

National parks and nature

The United States is famous for its national parks. Yellowstone became the world’s first national park in 1872.[5] It covers nearly 9,000 square kilometers, mostly in Wyoming, and has more than 300 geysers, about two-thirds of all the geysers on Earth.[5]

The Grand Canyon in Arizona is about 1,500 meters deep.[4] The Colorado River carved it over millions of years, and its rock layers show about 2 billion years of Earth’s history.[4] Standing at the edge, visitors can see layers of different colors, each one formed at a different time.

These two parks are UNESCO World Heritage sites, along with many other places in the country.[4][5][10] The United States also has high mountains, wide plains, deserts, swamps and long coastlines. Because the country is so big, students in different states may live in very different landscapes and climates.

Famous landmarks

The Statue of Liberty stands at the entrance to New York Harbor.[6] It was a gift from France to celebrate the 100th anniversary of American independence, and it was dedicated in 1886.[6] The sculptor Frédéric Bartholdi designed it, and Gustave Eiffel, the engineer later famous for the Eiffel Tower, built its inner steel frame.[6]

The statue holds a tablet with the date of the Declaration of Independence and stands over broken chains.[6] UNESCO explains that it became a symbol of freedom and democracy and also a welcome for millions of immigrants who arrived by ship.[6]

Independence Hall in Philadelphia, the Grand Canyon and Yellowstone are other landmarks that appear in many classrooms.[3][4][5] Washington, D.C., the capital, is home to the White House and the Capitol, where Congress meets.

People and languages

With about 342 million people, the United States has one of the largest populations in the world.[1] English is the official language, as stated in a 2025 executive order.[7] Many other languages are spoken at home too, especially Spanish, and many families speak two or more languages.

People in the United States have roots all over the world. Native Americans were the first inhabitants, and over the centuries people arrived from Europe, Africa, Latin America, Asia and other places. UNESCO notes that the Statue of Liberty welcomed millions of these newcomers.[6]

This mix is easy to see in daily life: in the foods people cook, the holidays they celebrate and the music they listen to. For students, learning about the countries their families came from is a great way to understand the United States.

Holidays and space exploration

The federal government lists eleven federal holidays.[8] They include Independence Day on July 4, Thanksgiving Day in November, Martin Luther King Jr.’s Birthday in January, and Juneteenth National Independence Day on June 19.[8] On Independence Day, many families watch fireworks and parades to celebrate the country’s birthday.

The United States is also known for space exploration. On July 20, 1969, NASA’s Apollo 11 mission landed on the Moon.[9] Neil Armstrong became the first person to walk on the Moon, followed by Buzz Aldrin, while Michael Collins stayed in orbit in the command module.[9]

From the Declaration of Independence to the Moon landing, many key moments in the country’s history happened in just under 200 years.[2][9] Students can explore the rest of North America on our continent page.
