Population Density: Computational Properties of Numbers
The human population of the earth is large and is increasing rapidly. Table 2.1 gives the estimates of the United States Bureau of the Census for the growth of the world’s population over the last 2000 years. This table reveals that the population in 1900 was approximately 1.6 billion. This increased to around 2.5 billion in 1950 and more than doubled over the next 40 years to exceed 5.6 billion in 1995. The Census Bureau estimates that the earth’s population reached 5.761 billion during April 1996.
