Click on history to review notes on historical aspects of human population growth and basic population parameters.

OVERALL GOALS FOR THIS TOPIC:

(1) To inform you about the current rate of human population growth in various regions of the world.

(2) To give you tools to use in evaluating claims that you hear or read about the current human population situation. The press and lay writers often make some serious mistakes in interpreting demographic data, and I want you to be able to evaluate critically various claims that you will encounter.

(3) While you will be given quite a few numbers (data on human populations), the point is not to memorize these numbers, but to master a few concepts and generalizations about regions of the world.
