Introduction of World population in the demographics is a total number of people

            World population in the demographics is a total number of peoples which is presently living. And it is assessed to reach approximately 7.7 BILLION people in 2019. The population is experienced the unremitting growth, in a end of a Great Famine of 1315-1317, as well as a  Black death during 1350, and it near to 370 million. A growth rates of the high population is the global population which increases the 1.8% per years, and it is occurred among the 1955 and 1975, and peaking to 2.1% among the 1965 and 1970. During past weeks supposed the use of the exponential, power, linear along with the polynomial functions with the mathematical models in the various contexts. Various type of function is also known as logistic functions and its occurs when explaining the various growth. The function whereas the exponential function is propagates rapidly at first, due to the limitations and its dwelling the limits on a size for underlying a population and it ultimately grow the slowly as well as level off (Kunen).

As shown in the above graph , the characteristics of S-Shaped in graph is the logistic function that presents the exponential growth that is followed through the period where the growth of population of slows along with the levels offs that approaching the maximum upper limits.

The formula of the logistic function is;

There are 3 parameters, like A , B , C where in this case the quadratic function is ;

Whereas C is represent the limiting value of the output in the below graph;

            The life expectancy of Global, which is enhanced in the current years, and its increasing an overall population of the life anticipation at the birth of the 70 years age. Population is aging a massive impact on an ability of a population growth which uphold the support ratio. During 2017, a majority of a world is going to face substantial growth in a 60 age brackets.

            The population of the World is increases where the growth rates of the populations is declining in a last century.  Growth rate of the population is very high in 1970 where everywhere about 2% growth of power years is declining in the 1980 (Zwelithini). In 2019 an annual growth rate of a world population is everywhere about the 1.1% as well as it is prophesied to decrease the smooth more for a few periods which is ongoing a tendency of a gentler of population growth.

            The importance of the population is explained; the target of the population is being studied and it is understand what data is referring for this. There are certain limitations by studying the populations, where it is mostly are too able and observed the individuals in the groups.  Whereas the study of the subpopulation is taking the statistical samples in the small portion for the larger population which is more accurately and it’s analyze the full spectrum, of the characteristics and behaviors of the population at large (Hoppensteadt F.C).

Description of Aim of World population in the demographics

        In this report the aim of the report is explains the matehemical exploration about the World Population. In this report first of explain the introduction about the population, then give some graphs with the proper equation in the mathematical forms.

Conclusion on World population in the demographics

            Summing up all the discussion, the exploration of the mathematical is about the population. As mentioned in the above discussion the aim of the exploration is fulfilled. It clearly explain the matehemical background of the populations. All the requirements and the purpose of the report is achieved, and the result related to the population growth is explained.
