United Nations: World Population Reach 10.1 Billion in 2011

In 2007, the United Nations announced that the human population on planet Earth has reached approximately 6.7 billion people. From the figures that about 7 billion people on this year, the United Nations predicts that world population will reach 10.1 billion.

According to official UN report titled 2010 Revision of World Population Prospect, the majority of the population spike was contributed by the countries whose citizens love to give birth. As many as 39 countries were in Africa, 9 in Asia, 6 in Oceania, and 4 in Latin America.

"Between 2011 and 2100, average growth rates in rich countries would be increased three fold," said the United Nations report, as quoted from DailyGalaxy, May 6, 2011. "The numbers rose from 1.2 billion to 4.2 billion," called the United Nations.

In use within the same period, the rate of population growth in countries with fertility rates 'average' only reached 2.6 percent, will rise from 2.8 billion to 3.5 billion.

However, the total population in developed countries the low level of fertility of its citizens declined 20 percent. The population which has now reached 2.9 billion 2.4 billion would be left alone in the coming year 2100.

In addition, the UN estimates that, globally, life expectancy humans also increased. From the age of 68 years in 2005 to 2011, the year 2095 and 2100, the average man lives to 81 years old.

More detail, in countries with high fertility rates, life expectancy reached 77 years of its citizens.

In countries with high fertility, life expectancy reached 82 years. As in countries with low fertility, in the year 2095 - 2100, people over there on average able to survive until the age of 86 years.

However, specifically on the report, the United Nations does not take into account the total population or life expectancy due to the increase in genetic technology, nanomedis, improving human intelligence and other factors or chance of reducing the number of population due to a variety of other risks such as war or outbreaks of infectious disease.
