Another quarter of the population inhabits the continent of Africa, where the African nations of South Sudan and Niger experienced a growth rate of 4. A specific example will clarify this point. Such growth is affected by factors such as war and contraceptive measures, the distribution of the population among age groups, and life expectancy at birth.
It is certain that there was no decline in the reproductive capacity; in fact, with improved health, the contrary is likely. In order to achieve early and Development was first held in Bucharest, Romania in August A family planning placard in Ethiopia.
Africa will experience the greatest percentage increase percent-from million today to million by the year Note first that the birth rate in the less-developed areas is higher than it was in pre-industrial western Europe.

Even if the death rate were to fall to zero, at the present level of human reproduction the growth rate would not be much in excess of three and one-half per cent per year, and the time required for world population to double would not fall much below 20 years.
Similarly, the transition to farming about 10, years ago greatly increased the overall food supply, which was used to support more people. Demographic transition and Sub-replacement fertility The theory of demographic transition held that, after the standard of living and life expectancy increase, family sizes and birth rates decline.
This difference results from the fact that in many less-developed countries almost all women at age 35 have married, and at an average age substantially less than in 18th-century Europe.Rapid population growth in impoverished nations presents unique obstacles as they strive for prosperity.
Elevated rates of growth in such countries also places a heightened burden on their governments, as they try to stretch their finite resources and infrastructure. Humans everywhere must understand that rapid population growth damages the Earth's resources and diminishes human well-being."
