Population

  • The world population (now 6.67 billion people) will reach 9.19 billion in 2050. This increase of 2.52 billion people is equivalent to the world’s total population in 1950. In the same period of time, the population in less developed regions is projected to grow from 5.45 billion to 7.95 billion. (Japan Times, 29 April)
  • The vast majority of this growth (2.5 billion) will occur in the developing world. The populations of the United States, Europe, and other developed countries will remain roughly the same in number, but will –along with the rest of the global population- age considerably. (The Futurist, 1 September 2007).
  • Between 2005 and 2050, half of the increase in the world’s population will be accounted for by a rise in the population aged 60 years and over. (The Futurist, 1 September 2007)
  • Net migration from developing countries to developed countries averages 2.3 million people a year (Japan Times, 29 April)
  • The number of children a woman gives birth to in her lifetime is expected to drop from 2.55 in 2005-2010 to 2.02 in 2045-2050 worldwide (Japan Times, 29 April)
  • As a result of decreasing fertility and increasing longevity, the number of people aged 60 years and over is expected to almost triple, jumping from 673 million in 2005 to 2 billion by 2050 (Japan Times, 29 April)
  • More than one billion people in the world live on less than one dollar a day. In total, 2.6 billion struggle to survive on less than two dollars per day. (“Fast facts: the faces of poverty”)
  • Currently, there are over 6 million displaced people worldwide, out of which approximately 3 million are in Africa. (Associated Press, 29 August 2007)
