Population Growth of the World’s Population over the Last Ten Years. (2002-2012)

Throughout the past ten years the worlds population has been increasing considerably due to certain factors in different countries. Some of these factors include birth rates, death rates and fertility rates.

The human population jumped considerably in 100 years from 1.6 billion to 6.0 billion in the years 1900-2000. A new century (20th) meant that despite having two world wars the standards of living started to improve and peoples’ life expectancy increased.

In 2002 the worlds population increased by 1.2 percent, which totaled to more than 6.2 billion people in the world. Once the rate of the increase had been translated into a net addition, it came to about 200,000 people per day being born, which also meant about 74 million people a year were born. This also roughly equalized to the population of Egypt in 2002.

Over the past 600 years, the global population has increased continuously, with the highest rate of growth coming in the 1950's an 1960's. The main reason for this growth is that the number of births has continued to exceed the number of deaths, and one of the reasons for this is the increasing standard of our healthcare. Even in the poorest parts of the world, there has been at least a minimal level of improvement. This means that more children are surviving birth, and adults are living for longer. Of note is that the average life expectancy in some parts of the world is nearly double what it was a few centuries ago. Although the number of children born to each family in the west is now a little smaller than it was in the 19th century, high historical mortality rates mean that a greater number survive into adulthood.

Most of the growth over the next few years is expected to occur in Asia and Africa, with population levels in the west having stabilised in some form. Many people in the developing world are already suffering from a lack of access to water, basic health care and sanitation, yet the population in these areas is increasing at a time when it might be better for there to be a period of stabilisation. Some experts have predicted that a lot of the industrial and economic growth in Asia and Africa over the past few years could be undone when the impact of the increasing population hits.

The main factors that actually cause the rapid growth in our population is the high birth rate, low death rate and immigrants.
