Ethnicity, Language, & Religion of the United States of America
Ethnicity
The United States is probably the most diverse country in the world when it comes to ethnicities. Trying to determine the exact breakdown of ethnic diversity is extremely difficult since most Americans are a combination of various ethnicities. Nearly 80% of the population is considered "white," but that includes those of European, Caucasian, and Arab descent including anyone who is a combination of these or a combination of European and American Indian descent, such as most of the Hispanic population. Another 15% is ethnically African, but again most of these people are a combination of varying African ethnicities, most of whom are descended from slaves brought to the country from Africa. The last 5% of so is primarily East Asian, wholly American Indian, Hawai'ian, etc. It is important to note though that many people of similar ethnicities tend to be found in similar geographic regions. For example New York City is home to most of the country's ethnic Jews and Italians, Chicago is home to many Poles and Irish, and Texas home to many Hispanics. Despite these concentrations, people of every ethnicity can be found in every part of the country and it's not uncommon for an individual to have ancestors of multiple ethnicities.
Language
The United States has no official language, although about 80% of Americans are native English speakers and another 11% are native Spanish speakers. Another 4% of the popular grow up natively speaking other European languages, 3% speak Asian languages natively, and smaller numbers speak other languages, primarily Native American Indian languages. Although the country doesn't have any official languages, the state of Hawai'i does; they recognize the language of Hawai'ian officially, which is a Polynesian language.
