Inthe estimated total population in India amounted to approximately 1. Total population in India India currently has the second-largest population in the world and is projected to overtake top-ranking China within forty years. In comparison with other countries whose populations are decreasing, such as JapanIndia has a relatively small share of aged populationwhich indicates the probability of lower death rates and higher retention of the existing population. With a land mass of less than half that of the United States and a population almost four times greater, India has recognized potential problems of its growing population.
India as a developing nation should deal quite tactfully with this issue. We work here to estimate the population growth of India since to using the logistic model approach and give a comparison with actual population of India for the same time period.
An error equation is also deduced based on the trend line for the specified time period and the population of India for the year and onwards till is estimated. The time required for India to reach its carrying capacity is also discussed.
A relevant conclusion is also made based on the obtained results. Modelsallow a better understanding of how complex interactions and processes work.
Modeling of dynamic interactions in nature can provide a manageable way of understanding how numbers change over time or in relation to each other. However, a plethora of patterns can be noticed and are brought forth by using population modeling as a tool.
There are various methods to develop a population model. A simple exponential model gives sufficient approximation in estimation of population but does not defines a saturation point. Hence the population estimated increases exponentially without any upper limit giving an unrealistic figure for longer time period.
This is because it does not considers the environmental factors and hence suitable for very short period of time.
Logistic model tells that the population growth rate decreases as the population reaches the carrying capacity or saturation point of the environment. The logistic model is more accurate than the exponential model .
Much work has been done to further develop these models so as to predict population growth accurately. This simple model only considers the excess of births over deaths per unit time and does not account for the limitation of resources.
Hence a suitable parameter is considered to modify the simple model using logistic law. This form is known as simple logistic model. The authors also indicate that this modified model explained very well growth of bacterial colony in a nutrient medium and also been successfully used to fit the data for human population.
An S-shape curve is obtained when the population is plotted against time. Apart from this the authors have proposes their own models to predict the population of bacteria. They also hint that the solution for basic equation of continuous-logistic model can be obtained by integrating the equation.
More details of this solution are discussed later in this paper.
The report also tells us that the death rate is much lesser than the birth rate hinting net increasing population of India. Carl Haub and O. He also points out that the increasing population of India is main reason behind the environment degradation.
He suggests that immediate remedial actions have to be taken to reverse the degrading trend.Identify top companies for sales and analysis purposes. compared to the previous year) Population growth in India previous year) Gross domestic product (GDP) growth rate in India.
The statistic shows the growth rate of the real gross domestic product (GDP) in India from to In , India's GDP growth was at about percent compared to the previous year. India’s Population: Becoming Number One.
India is poised to overtake China as the world’s most populous country by Poverty is linked to fertility rates, and individual and government attention to population trends contributes to sustainable development. India’s rate of urban population growth is expected to climb, partly due to.
If fertility growth rate is not continuously decreasing & population increase day by day then by India will cross China and will became most populated country of the world. In , China applied ‘One Child Policy’ so that now we can see the effect of that policy. Mumbai's urban population is estimated to be over 22 million, and the densely populated city is the largest in India in terms of population, trade activity and business.
The metropolitan area has experienced an explosion in growth over the past 20 years, a common occurrence with metropolitan areas in India.
