Population momentum is the growth of a population if reproduction were immediately reduced to replacement-level fertility. This population growth is due to the current number of organisms in the childbearing age-range.
Thereof, how does population momentum effect population growth?
Population momentum impacts the immediate birth and death rates in the population that determine the natural rate of growth. If the fertility rate remains higher than the replacement rate, the population would continue to grow.
Also Know, what age group gives populations the greatest momentum for growth? Population growth has a lot to do with the age structure of the population. The higher the percentage of young people (especially those under age 15), the more the population will continue to rise as this large cohort (segment of the population) enters their reproductive years (15-49).
Similarly, it is asked, what does population momentum mean?
Population momentum refers to population growth at the national level that would occur even if levels of childbearing immediately declined to replacement level. For countries with above-replacement fertility, population momentum represents natural increase to the population.
What is population momentum quizlet?
Population Momentum (inc) The continued population growth which is observed even with the reduction of birth rates and increase in mortality rates. Population Momentum (dec) The continued population decrease observed even with the increase of birth rates and decrease in mortality rates.

What is the population momentum effect?
Population momentum is the growth of a population if reproduction were immediately reduced to replacement-level fertility. This population growth is due to the current number of organisms in the childbearing age-range.
What is an example of demographic momentum?
Phenomenon. Even in the face of extreme measures aimed at lowering reproductive rates, the population will continue to grow due to a large proportion of its population entering its reproductive years. For example, when China first introduced its one-child policy, population growth continued regardless.
What are demographic regions?
Demographic Regions. Shows how different parts of the world are in different stages of the demographic transition. Demographic Transition Model. Has 5 steps. Stage 1 is Low Growth; Stage 2 is High Growth; Stage 3 is Moderate Growth; Stage 4 is Low Growth/Stationary; and Stage 5 is a Negative Growth.
How can we achieve zero population growth?
In the long term, zero population growth can be achieved when the birth rate of a population equals the death rate, i.e. fertility is at replacement level and birth and death rates are stable, a condition also called demographic equilibrium.
What are the four stages of demographic transition?
The concept is used to explain how population growth and economic development of a country are connected. The concept of demographic transition has four stages, including the pre-industrial stage, the transition stage, the industrial stage, and the post-industrial stage.
What is age distribution?
Age distribution, also called Age Composition, in population studies, the proportionate numbers of persons in successive age categories in a given population. A population with persistently high fertility, for instance, has a large proportion of children and a small proportion of aged persons.
What is meant by population stabilization?
1. the condition of not changing the total number of people in a country. All countries must make a commitment to resource conservation and population stabilization.
What is population hidden momentum?
The term hidden momentum of population growth refers to the phenomenon of continuous increase in the population of a country even though there is fall in the birth rate of that country. This is so because the youth population becomes the population base of potential parents.
Who gave the theory of demographic transition?
Warren Thompson
What is demographic momentum in human geography?
Demographic momentum. this is the tendency for growing population to continue growing after a fertility decline because of their young age distribution. This is important because once this happens a country moves to a different stage in the demographic transition model.
What is the difference between population change and natural increase?
Rate of change Births and deaths are natural causes of population change. The difference between the birth rate and the death rate of a country or place is called the natural increase. The natural increase is calculated by subtracting the death rate from the birth rate.
What are the most populous countries in the world?
Ten Countries with the Highest Population in the World. are China, India, United States, Indonesia, Pakistan, Brazil, Nigeria, Bangladesh, Russia and Mexico.
Is there evidence that an increase in per capita income stimulates population growth?
No there is no evidence that an increase in per capital income stimulates population growth. This is an assumption of the Malthus trap but one not borne out by the evidence. The outcome depends on the relative contribution of population and human capital in the determination of the growth rate of income per-capita.
What is the theory of demographic transition?
Theory of Demographic Transition is a theory that throws light on changes in birth rate and death rate and consequently on the growth-rate of population. Along with the economic development, tendencies of birth-rate and death rate are different. Because of it, growth rate of population is also different.
What determines biotic potential?
Biotic potential is the ability of a population of living species to increase under ideal environmental conditions – sufficient food supply, no predators, and a lack of disease. An organism’s rate of reproduction and the size of each litter are the primary determining factors for biotic potential.
What is population inertia?

Why will a youthful population still be growing in size even after it has reached replacement fertility?
What is population momentum? Thanks to a phenomenon known as population momentum, a youthful population with constant levels of mortality and a net migration1 of zero continues to grow even when fertility remains constant at the replacement level.
