In general, population growth is driven by a higher birth rate than death rate, though several smaller factors impact that ratio comparison. The assumed belief before Quetelet and Verhulst worked on population growth was that an increasing population followed a geometric progression. Population growth depends on a combination of birth rate and death rate and is affected by the carrying capacity of the environment. 39, ST/SOA/Series A/39 . population growth and increased human density relate to economic well-being in the developing world. Through the modern discoveries like transportation, equipment, agricultural tools, etc help make our life more comfortable, they have created pressure on the natural resources.

Humans, unlike other species, have the ability and intelligence to grow beyond what would otherwise be the environmental carrying capacity, witnessed by the dramatic growth of the world population in recent decades. Such growing population conserves various natural resources to fulfill various requirements. More precisely, the formula is: doubling time = 100 ln2 / g, where ln2 is the natural logarithm of 2 (0.693) and g the percentage growth rate.So it would be slightly more precise to use a ‘Rule of 69’, but 72 is chosen because more numbers divide evenly into it, and it is good enough for an approximate rule of thumb.

Google Scholar Bourgeois-Pichat, J. The relationship between population growth and growth of economic output has been studied extensively (Heady & Hodge, 2009).Many analysts believe that economic growth in high-income countries is likely to be relatively slow in coming years in part because population growth in these countries is predicted to slow considerably (Baker, Delong, & Krugman, 2005). In particular, population density plays the most important role in shaping the socio-economic environment. Abelson, P.H., (1990).

Population growth is the rate at which a population grows or expands. Population growth is the increase in the number of individuals in a population.Global human population growth amounts to around 83 million annually, or 1.1% per year. If facilities can keep pace with growth, then the increase in contact rates can be kept to a minimum, and the potential reversal in the epidemic transition prevented. Population growth can either operate as a negative factor, increasing pressure on limited arable land, or a positive factor, helping to induce intensification through adoption of improved technologies and higher labor inputs.
