U.S. is a large country; it will be more fascinating to explore America's demography. But how can they count the population? What are the features of this nation? How can we research demography?
I know that there are whites and blacks. Blacks or Afro-Americans are the minorities in this country. Are blacks the only minorities? I do not think so. I would like to find the answers in my thesis. There are Hispanics, Chinese, Italians, and Russians. There are immigrants and native-Americans. Today in every section of the political, business, and public life we can name people who are members of the U.S. minority. For example Colin Powel, the ex- foreign secretary, is Afro-American. On the movie screen we can observe more people who are minority members. But how many ethnical groups are there in the U.S.? How can we count them? The answer is: Census.
