2020 will live 7.7 billion people on the earth if the present increase in population of approx. 80 million per year further continues. Whether now this are too many or too few people, everybody should decide for himself in a free and democratic world.
Already then some people talk about an overspill population. Which ones from the 194 states on the earth were already now overpopulated, however?>>>To the ranking list of the most overpopulated states >>>
Criteria for building the ranking list >>>
Result: Japan, South Korea and Germany are hereafter the most populous states.With every forecast of a future population removal scenarios of dying out are designed by politics and media. On the other hand, what talks about the fact actually that the population in Germany goes back of 82 m. on it from France (60 m.), Spain (40 m.) or even Sweden (10 m.)???> Power and money, because only a large market promises wealth for the rich and power for the ruling. Unfortunately, only more become the poor. Therefore:
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. www.census.gov/ipc/www/popclockworld.html, www.census.gov/ipc/www/img/worldpop.gif, www.ecopop.ch, www.weltbevoelkerung.de, www.un.org/esa/population/unpop.htm, www.bib-demographie.de, http://members.aol.com/jspanalysis/analysis/wachst4.htm). For the animation shown here 34 times were used and in a second the development of 100 years is represented.
