East coast and west coast are terms used in the eastern and western coastal States of the United States. The United States is a vast country with its coast bordering on the Pacific Ocean and the Atlantic Ocean.

In the United States, the east coast refers to the easternmost state, starting from the Atlantic Ocean in the east and reaching Canada in the north. They are also called the East Coast. Nearly 36% of the population in the United States lives in the East Coast States.

States on the east coast include Maine, Massachusetts, New Hampshire, Connecticut, Rhode Island, New Jersey, New York, Maryland, Virginia, Delaware, and North Carolina, South Carolina, Florida and Georgia in the south. Some states are not directly related to the Atlantic coast, but are regarded as states on the east coast.

In the United States, the west coast refers to the westernmost coastal country that contacts the Pacific Ocean. It is also called the Pacific coast. Nearly 17% of the population in the United States lives in the west coast States.

The west coast includes five states: Washington, Oregon, California, Alaska and Hawaii. Alaska and Hawaii do not belong to the continental United States or the neighboring United States; They are near the Pacific Ocean, so they are included in the west coast. Sometimes, inland states like Arizona and Nevada are also included in the states on the west coast.
