In this video / article Hans Rosling blows up some misconceptions and misunderstandings about population growth. He convincingly makes the following points: 1) Population growth should hit a limit around 11 billion within the next hundred years, as the world equalizes in health outcomes. 2) In developed countries, a ratio near 2 parents to 2 children mostly exists. As a result of equalizing health outcomes, low child mortality, and family planning, family sizes go down, and population growth slows in a predictable way. 3) Current population trends are strong enough that by 2100, only ~10% of the world population will be in Western nations (North America, Western Europe) — Africa will quadruple in population and Asia will increase about 25%.
