World Population Reaches 7 Billion in This Year

World population will reach seven billion by the end of this year, according to a recent study published in France on Thursday (08/18/2011). African continent is still experiencing a huge surge in population growth while the rest of the world tends to decline due to restrictions on birth rate. Being in the top four big state with largest population, China, India, USA and Indonesia.

Study Institute, the National Institute for Demographic Studies (INED), predicts that the overall world population will continue to happen until it becomes stable at 90-10 billion figure at the end of this century. Of the six billion people, according to estimates in 1999, world population increased by one billion in just 12 years.

INED estimates, it took 14 years to reach eight billion people, before numbers began to stabilize. The study was undertaken together with the UN, the Bank Dunai and a number of other institutions.

Global population growth surged since the 19th century. "Total world population has increased seven-fold over the last two hundred years, to surpass seven billion in 2011, and is expected to reach nine or 10 billion by the end of the 21st century," the report said.

Half of the world's population lives in seven countries. Because of this demographic shift in those countries will have a major influence. China was top of the list with a total population of more than 1.33 billion people, one after another in India with a number of 1.17 billion. Five other countries, according to the order, is the United States, Indonesia, Brazil, Pakistan and Nigeria.

INED estimates, by 2050 India will become the most populous state. Beijing's one-child policy will make China's population growth is at a moderate level.

According to the INED, although the total world population continues to grow, its growth rate has declined. World population growth rate at 1.1 percent this year, badingkan with 50 last year by 2 percent. It happened because the level of total births per woman fell to 2.5 children, half of the figure recorded in 1950. But there is a difference between regions is very large. In Africa the average was 4.7 children per woman, while in Europe only only 1.6 children per woman.
