SUDAN YEMEN There are more than twice as many people on the planet today as there were in 1960. World population has never doubled this quickly before, but it is unlikely to double again. The era of explosive growth is expected to end by 2050, at more than 9 billion people, with an esti- mated range of 8 to 10.5 billion people. Youthful momentum Age-distribution pyramids (right) show why the overwhelmingly young populations of developing countries will produce almost all the future population increase. Even with falling birthrates, the world's population is still growing by about 80 million people a year. The Shape of Seven Billion Each country in this cartogram is sized according to its projected population in 2011. Black dots represent the country's population in 1960; light dots are population added since then. Each dot represents two million people. Colors indicate the amount of growth (detailed below). Nations with populations under 1.5 million are not shown. POPULATION The less developed world will account 3 billion 1960 7 billion 2011 World population Europe collectively grew 21%.
