If current demographic trends continue, however, Islam will nearly catch up by the middle of the 21st century. Both the positive checks of hunger and disease referred to by Malthus do not operate today, except the terrible disaster sometimes caused by Tsunami, Katrina, Rita and floods or rains in desert areas like Banner and Jaisalmer in August In it, he argued that population multiplies geometrically and food arithmetically ; therefore, whenever the food supply increases, population will rapidly grow to eliminate the abundance.
Some predicted that human species would die out. Or if disaffiliation were to become common in countries with large Muslim populations — as it is now in some countries with large Christian populations — that trend could slow or reverse the increase in Muslim numbers.

Increased birth control is one reason for their lower fertility rates but so are decisions by women to stay in school longer, to go to work right after their schooling ends, and to not have their first child until somewhat later.
During the depression of the s, the debate changed somewhat because the birth rate fell sharply in industrial western nations. Over the coming decades, Christians are expected to experience the largest net losses from switching.
The Chinese philosopher, Confucius argued that a numerical balance be maintained between population and environment. Demographic transition theory links population growth to the level of technological development across three stages of social evolution.
Two of every three species is estimated to be in decline. Phillip Connor prepared the migration input data, wrote descriptions of migration results and methods, and helped write the chapters on each religious group and geographic region.
The third stage marks the beginning of the decline in the birth rate due to socio-economic changes and the fourth stage stabilises this trend and establishes a low and steady population growth rate. Demographic transition is a term, first used by Warren S. Globally, about 40 million people are projected to switch into Christianity, while million are projected to leave, with most joining the ranks of the religiously unaffiliated.
Since it is not possible to measure O, this formula is only of academic interest. He said the gap between the food supply and population will continue to grow over time. But the optimum theory takes a realistic view when according to this, the law of diminishing returns does not operate in agriculture immediately but after the optimum point is reached.
Modern drugs are used by the people.
He was the first who gave the concept of optimum population level. The optimum theory of population is superior to the Malthusian theory on the following grounds: Data on subgroups of the unaffiliated are also unavailable in many countries.

Population growth projections feed into many other forecasts and models - projections of energy use, for example, or corporate profits - so people like Sanyal scrutinise these UN figures carefully.
Population growth is driven by three different factors: mortality, fertility, and population momentum. The World Fertility Rate The visualization below shows the total fertility rate by the level of development and includes the UN projections through The chart below shows that global population growth reached a peak in and with an annual growth rate of %; but since then, world population growth was halved.
For the last half-century we have lived in a world in which the population growth rate has been declining. Sacred to the memory of the Rev THOMAS ROBERT MALTHUS, long known to the lettered world by his admirable writings on the social branches of political economy, particularly by his essay on population.Three views of population growth
