Tie population of the United States is becoming more diverse. The circle graphs below show the distribution of the U.S. population among five ethnic groups in 1990 and 2000. The estimated total U.S. population for those two years was 2.488 X 108 in 1990 and 2.754 X 108 in 2000. 

By how much did the total U.S. population increase between 1990 and 2000 What was the percent increase during this period  

Calculate the total population for each of the five groups for 1990 and 2000. 

Make a bar graph that compares the population for the five groups in 1990 and 2000. In what ways is the bar graph better than the circle graphs In what way is it less useful
