How do I find the racial/ethnic, lanuage, and religious demographics of a popluation of 6 million
This site lists all of that information about the countries and territories of the world.

Thank you for using the Hiskha Homework Help Forum. If you have a "Search Engine" on your computer, I entered "World Population Cencus" and here is only one sige:
Population Census http://www.stat.go.jp/English/data/kokusei/index.htm
Also, if you have access to an up-to-date Atlas, you will find each country lists the population plus the other information you are searching for.
Still another idea, when you find the countries you want, the Search Engine (especially the CIA Fact Book) will list that information.
Good luck! If you have any further difficulty, be sure to get back to us!
