The population growth on the earth

The animation points the development of the world population with a resolution of 1 pixel = 1 year × 20,000,000 people (details >>>)

Details for the animation:

For the time period 1500 < t < 2020 the following function was chosen as an interpolation approach:

Total population( t ) = b × exp( a × t / | c - t | ), with a, b > 0, c > 2020

The parameters a, b, c were decided according to the method of the smallest squares under the auxiliary condition that the most current total population as exact is accepted. The interpolation function represents a development of the compensation from most different statistics of total populations (e.g.,,,,,, For the animation shown here 34 times were used and in a second the development of 100 years is represented.
