Human Population Predicted To Reach 12 Billion By 2100 At 7.2 billion, the human population is already a serious burden on resources and a threat to the environment and species. Imagine, then, how dire the global situation would be if we were to reach 12 billion, because if the current rate continues, that is what our planet may be facing at the turn of the next century. According to a new study by the United Nations (UN) and the University of Washington, there is an 80% probability that the world population will reach between 9.6 and 12.3 billion in 2100. That’s around 2 billion higher than previous estimates. “The consensus over the past 20 years or so was that world population, which is currently around 7 billion, would go up to 9 billion and level off or probably decline,” study author and statistician Adrian Raftery said in a news release. “We found there’s a 70 percent probability the world population will not stabilize this century.

Earth Population as Village of 100 Claim: List summarizes what proportions of common traits would be like if we could shrink the earth's population to a village of precisely 100 people.

Human Numbers Through Time By Susan K. Lewis Posted 04.20.04 NOVA For most of human existence our ancestors led precarious lives as scavengers, hunters, and gatherers, and there were fewer than 10 million human beings on Earth at any one time. Today, many cities have more than 10 million inhabitants each, and populations continue to skyrocket. Trace the dramatic growth of human populations over recent centuries on our global map, and see where on Earth as many as three billion more people may live by 2050.

International Programs - Information Gateway Frequently Asked Questions (FAQ) 1. What is the International Data Base? The International Data Base (IDB) offers a variety of demographic indicators for countries and areas of the world with a population of 5,000 or more. The World's Population Might Not Be About Numbers After All In a world with limited resources, we have to conserve what we have and reduce the number of people on the planet—at least, that’s what most of us believe. But is this true? That’s the provocative question raised by the new documentary Misconception. The film, which premieres at the Tribeca Film Festival on April 20, gives us a personal look at the social and political ramifications of population growth. Oscar-winning director Jessica Yu (best documentary short subject) began exploring the issue of population growth while making her previous documentary, Last Call at the Oasis, which is about the global water crisis. During every post-viewing question-and-answer period, “we literally had people saying, Your next film has to be about population growth,” says Yu.

A closer look at communities thriving in unexpected places In Caracas, the capital of Venezuela, nearly 70 percent of the population lives in slums that appear to drape like silk over every hill of the city. Iwan Baan: Ingenious homes in unexpected placesIwan Baan is not as interested in what architects build as he is in the beautiful ways that people appropriate the spaces once the planners are gone. In today’s talk, Baan — whose breathtaking image of lower Manhattan after Hurricane Sandy hangs on at least one of our walls — shows incredible images from communities thriving in ways that seem quite opposite to the uniformity of suburbs. First, Baan takes us to Chandigarh, India, where people inhabit buildings created by modernist architects Le Corbusier in very different ways than expected. Then, Baan takes us to Caracas, Venezuela, where an abandoned 45-story building has become a miniature city.
