Changes in world Population

The world population is the total number of living humans on Earth at a given time. As of July 2008, the world's population is estimated to be just over 6.684 billion. In line with population projections, this figure continues to grow at rates that were unprecedented before the 20th century, although the rate of increase has almost halved since its peak of 2.2 percent per year, which was reached in 1963. The world's population, on its current growth trajectory, is expected to reach nearly 9 billion by the year 2042.
