"It took all of human history to reach a world population of 1.6 billion in 1900. By 2000, it was
6.1 billion. How did this change happen? The answer lies in the
demographic transition—the shifts in birth and death rates that
historically have occurred over long periods of time—and how differently
it has taken place in developed and developing countries."

The world population will pass 7 billion this week. Here is a great website for discussing everything related to world population from infant mortality rates to life expectancy. There is an interactive map and a video to use for discussion and tons of data to use for comparison.
