Hans Rosling, the Swedish statistician known for turning data into performance, argues that most people badly misjudge where world population is headed and why. Using animated bubble charts and floor-sized infographics built by Gapminder, he tracks fertility rates, income, and family size across decades, showing that the number of children per woman has already fallen close to replacement level in most of the world. He visits families in Bangladesh and other countries once assumed to be locked into runaway growth, using their actual living conditions to test the assumptions behind old population predictions. Rosling's target is the instinct to picture the planet as a single undifferentiated mass of poor, high-birth-rate countries, when the data shows income and health rising fast enough to bring birth rates down on their own. The film builds toward a population plateau rather than an explosion, driven by falling child mortality and rising education rather than by coercive limits. It first aired on the BBC in November 2013, and its case rests entirely on the numbers Rosling puts on screen.
