The United States has dramatically changed from its beginnings as 13 little-known colonies. Its population of 300 million people represents almost every national and ethnic group in the world. Progress continues in economics, technology, culture and society. Americans live in an interdependent, interconnected world. The United States still is connected to the values of its early days. Among these are a belief in individual freedom and democratic government and the promise of economic opportunity and progress for all people. The work for the United States is to keep its values of freedom, democracy and opportunity secure and vital in the 21st century.
