For the first one-half million years of human existence, the population growth rate was about zero. 1). [4] However, some academics outside the UN have increasingly developed human population models that account for additional downward pressures on population growth; in such a scenario population would peak before 2100. It is straightforward to integrate this equation by partial fractions and show that resulting solution is indeed an S-shaped, or sigmoid, curve. If the current growth rates continue, it will have 1.63 billion people by 2050 and will become the most populous country surpassing China. This increase in population is continued till large amount of food materials exist in the habitat. In some geographies, this has slowed through the process called the demographic transition, where many nations with high standards of living have seen a significant slowing of population growth.
