A. Use the world population and land area table.
What was the mean population of all inhabited areas except Asia in 2000?
Answer
World total=6,279,000,000
Population of Asia=4,028,000,000
So reat population=6,279,000,000-4,028,000,000=2,251,000,000
Number of regian=5
Mean=2,251,000,000/5=450,200,000
