People of United States of America (USA)
The United States of America is world's third-largest country in terms of population. This nation, in the past, has attracted vast numbers of immigrants from around the globe. Yet, the country remains less densely populated than other large countries or other industrialized nations. In 2003, there were 30 persons per sq km (78 per sq mi). For a large country, the United States is also remarkably uniform linguistically and culturally.
Arts, Culture and Music of United States of America (USA)
The United States is a country where immigrants from various ethnic and racial backgrounds forego their traditional traits and join with other Americans to create a new identity. The people who came to the United States brought in their culture and once here, they borrowed cultures from each other. This trend continued for generations and today, American culture is an infusion of various elements from Europe, Africa, Asia, and Latin America. This has, in turn, made American culture rich and complex. For example, African Americans brought in the music and rhythms of blues and jazz that became the nation's most globally popular cultural form. Although America's culture is becoming more uniform, its society remains a diverse mix of ethnic, racial, and religious groups.
The flag of the United States has thirteen equal horizontal stripes of red (from top to bottom), alternating with white. There is a blue rectangle in the upper hoist-side corner bearing 50 small, white, five-pointed stars arranged in nine offset horizontal rows of six stars (from top to bottom) alternating with rows of five stars. The 50 stars represent the 50 states, the 13 stripes represent the 13 original colonies known as Old Glory.
Economy of United States of America (USA)
The US has the largest and most technologically powerful economy in the world, with a per capita GDP of $37,600. In this market-oriented economy, private individuals and business firms make most of the decisions, and the federal and state governments buy needed goods and services predominantly in the private marketplace. US business firms enjoy considerably greater flexibility than their counterparts in Western Europe and Japan in decisions to expand capital plant, lay off surplus workers, and develop new products. At the same time, they face higher barriers to entry in their rivals' home markets than the barriers to entry of foreign firms in US markets. US firms are at or near the forefront in technological advances, especially in computers and in medical, aerospace, and military equipment, although their advantage has narrowed since the end of World War II.
