Instructions for creating your graph.
1. Place time on the horizontal access. Values should range from 1650 to 2050.
2. Place number of people on the vertical access. Values should range from 0 to 20
billion.
3. Make sure that your graph is a full page in size and you have the correct labels for
the X and Y access and a title for your graph.
Analysis #1 (answer on separate paper)
1. It took 1649 years for the world population to double, going from .25 billion
people to .50 billion people. How long did it take for the population to double once again?
2. How long did it take for the population to double a second time? A third time?
3. Based on your graph, in what year will the population reach 8 billion?
4. Based on your graph, how many years will it take for the population of 2009 to double?
