INTRODUCTION - POPULATION GROWTH The world experienced dramatic population growth during the twentieth century‚ with the number of inhabitants doubling from 3 to 6 billion between 1960 and 2000. India‚ too‚ saw very rapid population growth during this period – from 448 million to 1.04 billion – and to 1.21 billion in 2010. The effects of past and projected future demographic change on economic growth in India is the main focus of this chapter. Figure 1 plots world population from 1950 to

number of factors that can contribute to the growth of a population and these trends can be seen in a number of species. It is generally believed‚ from an ecological perspective‚ that populations will display either an exponential of logistic growth rate. If optimal environments are consistently maintained with no biotic or abiotic limiting factors (excess food‚ excess space availability‚ optimum climactic environment‚ no predation‚ etc) then a population will grow in an exponential direction.

PERSPECTIVES ON POPULATION GROWTH Based on the current trend‚ there will be a total to about 9.2 billion people on the earth by mid-century‚ fuelled by the birth of 220000 children a day and falling mortality rates (Population Institute‚ 2014). This estimate raises questions about the future of humanity and the planet we inhabit. The debate about an optimal size for human population is one that has waged over the years. The question is fundamentally about sustainability; whether the resources that
