This is a fascinating graphic that shows the total number of people who ever lived, as well as a whole host of other information about them. The text reads:
The numbers are highly speculative but are as accurate as modern science allows. It’s widely accepted that prior to 2002 there had been somewhere between 106 and 140 billion homo sapiens born to the world. The graphic below uses the conservative number (106 bn) as the basis for a concentric circle graph. The red dot in the center is scaled to represent how many people are currently living (red) versus the dead (white). The vertical line represents time. The spectral graph shows the population ‘benchmarks’ that were used to estimate the population over time. Adding up the population numbers gets you to 106 billion. The two spheres are then used to compare against other numbers.
The hypothetical maximum ‘carrying capacity’ of the earth based on current trends, known resources and existing technologies. The world population is expected to reach this size around 2050.
