World Population Will Grow Fastest in Poorest Areas
nature.com — The world's least-developed regions will double in population between now and 2050, from 828 million to 1.66 billion, predicts the non-profit Population Reference Bureau, based in Washington DC, in data published last week. More…

"By 2050, India will overtake China as the world's most populous country." - a highly disappointing news to many, but not all, of us Indians. In my reckoning, that could happen much earlier. In fact, unrestricted population growth is the price we have to pay for our multiparty `decocratic' system of government. For all practical purposes, talking of polulation has become a taboo in political circles. The country has been just waiting for a good sense to descend on our poor masses, who would then realise the gravity of the scenario. But that may take a few centuries, perhaps, and nobody can be sure of the shape this globe may assume by that time. o 21 Aug, 2009 o Posted by: Yogendra Joshi www.nature.com/news/2009/090819/full/460943b.html

Globally, the growth rate of the human population has been steadily declining since peaking in 1962 and 1963 at 2.20% per annum. In 2007 the growth rate was 1.19% per annum. The last one hundred years have seen a rapid increase in population due to medical advances and massive increase in agricultural productivity[3] made possible by the Green Revolution.[4][5][6]
The actual annual growth in the number of humans fell from its peak of 87.5 million per annum in 1989, to a low of 76.4 million per annum in 2002, at which it stabilised and has started to slowly rise again to 79.4 million per annum in 2007, and 80.2 million per annum in 2009. Growth remains high in the Middle East, South Asia, Southeast Asia, Latin America, and primarily in Sub-Saharan Africa.[7] According to projections by the U.S. Census Bureau, the annual world population growth will peak in 2011 at 80.9 million.[8]
Some countries experience negative population growth, especially in Eastern Europe (mainly due to low fertility rates and emigration). In Southern Africa, growth is slowing due to the high number of HIV-related deaths. Some Western Europe countries might also encounter negative population growth.[9] Japan's population began decreasing in 2005 [10 en.wikipedia.org/wiki/Population_growth

The term world population commonly refers to the total number of living humans on Earth at a given time. As of 24 August 2009, the Earth's population is estimated by the United States Census Bureau to be 6.78 billion.[1] The world population has been growing continuously since the end of the Black Death around 1400.[2] There were also short term falls at other times due to plague, for example in the mid 17th century (see graph). The fastest rates of world population growth (above 1.8%) were seen briefly during the 1950s then for a longer period during the 1960s and 1970s (see graph). According to population projections, world population will continue to grow until around 2050. The 2008 rate of growth has almost halved since its peak of 2.2% per year, which was reached in 1963. World births have levelled off at about 134-million-per-year, since their peak at 163-million in the late 1990s, and are expected to remain constant. However, deaths are only around 57 million per year, and are expected to increase to 90 million by the year 2050. Because births outnumber deaths, the world's population is expected to reach about 9 billion by the year 2040.[3][4] en.wikipedia.org/wiki/World_population

What is the basis of the estimate? Are they only using birth rate statistics? Does it take into account the high mortality rate, low hygiene and general health care in these and available technology and resources ready to maintain the population?

Oh god,hopefully people will see it as soon as possible and stop having children since this planet is so overpopulated
It seems that those in the poorest regions and also very tied to tradition and definitely not very educated and therefore open minded.
Thats why,when they know better they'll stop mindlessly breeding like rabbits
