The United States of America is the most culturally diverse  country in the world in terms of culture religion, ethnicity  and sexual orientation. As a combination of various races and cultures, America is home to all. The culture here is so unique that citizens can be just as proud of their original cultural heritage  as they are to be American.  What is now the US was initially inhabited  by native people until the land was settled by various European groups and African slaves. Since the 20th century, the country has become a heaven for people from all over the globe .  The arrival of immigrants  has shifted populations from rural  areas into cities because immigrants tend to settle in urban areas. At present, 81 percent of the inhabitants in the US live in cities. Cultural and ethnic diversity adds a unique flavor to cities that is expressed through distinct  neighborhoods, restaurants, places of worship, museums, nightlife and multicultural learning environments. Unique musical forms, such as jazz, rock and roll, Chicano music, and the blues, grow in the US by mixing a variety of culturally distinct musical traditions to create a new form. At the executive   level, the country is headed by a mixedrace president; two posts  on the Supreme Court are held by members of the country's two largest minorities.There is also diversity in state and local governments. Without its rich mixture of races and cultures, America would not be the nation that it is today. Founded upon the basis of equality and freedom, America acts as a stage where different cultures not only coexist peacefully, but develop well.
