What does demographic momentum mean?
What does Demographic momentum mean? Here are all the possible meanings and translations of the word Demographic momentum. Demographic momentum The tendency for growing population to continue growing after a fertility decline because once this happens a country moves to a different stage in the demographic transition model.
What is population momentum Quizlet?
Population momentum occurs when a country’s fertility rate declines to or below replacement level (2.1 children per woman), yet the population size continues to grow due to the age structure of the population. The higher the percentage of young people in a population, the more growth the country will see, even long after fertility rates drop ...
What is population momentum?
What is Population Momentum? 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).
What is the definition of Population momentum?
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 an example of demographic momentum?
Example of Population Momentum For world population, the UN projections shows global fertility rate dropping to replacement level sometime in the middle of this century. Due to population momentum, the size of our global population is expected to grow beyond 2100.
What is population momentum in demography?
For a given population, total population momentum is the size of the hypothetical stationary population achieved by projecting today's starting population with replacement fertility, zero net migration, and today's constant death rates, divided by the size of the starting population today.
What are demographics in human geography?
Demography is the study of demographics, the social characteristics and statistics of a human population. This study of the size, age structures, and economics of different populations can be used for a variety of purposes.
What is demographic equation AP Human Geography?
Demographic equation. The formula that calculates population change. The formula finds the increase (or decrease) in a population. The formula is found by doing births minus deaths plus (or minus) net migration.
Why is population momentum a matter of interest in population projections?
Population momentum explains why a population will continue to grow even if the fertility rate declines. Population momentum occurs because it is not only the number of children per woman that determine population growth, but also the number of women in reproductive age.
Why is population momentum important?
At times when an increasing share of women enter the reproductive age bracket the population can keep growing even if the fertility rate is falling. This is what demographers refer to as 'population momentum' and it explains why the number of children in the world will not decline as rapidly as the fertility rate.
What are demographics examples?
Demographic information examples include: age, race, ethnicity, gender, marital status, income, education, and employment. You can easily and effectively collect these types of information with survey questions.
What is demography in simple word?
Demography is the science of populations. Demographers seek to understand population dynamics by investigating three main demographic processes: birth, migration, and aging (including death).
What is the difference between demography and population geography?
Demography studies the growth of population and the size, structure and distribution of this growing population. Population geography is the study of the division of humans over geographical factors. This area is interested in studying the population growth patterns related to natural living places.
What is demographic momentum quizlet?
Demographic Momentum. The tendency for growing population to continue growing after a fertility decline because of their young age distribution. Demographic Regions.
How are the DTM and ETM related?
The ETM describes causes of death in each stage of the DTM. The Epidemiological Transition Model focuses on why death rates are high or low.
What is Stage 3 of the demographic transition model?
Stage 3: Total population is rising rapidly. The gap between birth and death rates will narrow. Natural increase is high. Death rates will now remain low and steady (to 15 per 1,000) but birth rates will fall quickly (down to around 18 per 1,000).
What is demographic momentum?
Demographic momentum is the tendency for growing populations to continue growing after a fertility decline because of their young age distribution.
Why is demographic momentum important?
This is important because once this happens a country moves to a different stage in the demographic transition model .
How does population growth affect the population?
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). Once this young group moves beyond childbearing age, however, the momentum will decrease, and population can begin to stabilize so that births and deaths balance (assuming fertility rates remain at or below replacement levels).
How long can a population continue to grow?
In fact, due to population momentum, a country’s population can continue growing for another 70 years once replacement level fertility is reached.
How much of Malaysia's population is under 15?
Yet, with 25 percent of its population under age 15, Malaysia is expected to grow until 2070 (according to UN projections), at which time the country’s under-15 cohort will have dropped to 15 percent of the population.
Why Does Population Momentum Matter?
Projecting populations is paramount to planning for the future, whether it’s on a local community scale, a national scale, or a global scale. Leaders need to know how many people will require food, jobs, homes, educations, energy, and the many other necessities of life, not only tomorrow but well into the future. This knowledge can be a key determinant in whether people get the resources and services they need, and ultimately experience a high quality of life.
When should population momentum be taken into account?
Population momentum must be taken into account when projecting future needs to avoid the common misconception that fertility rate, mortality rate, and net migration are the only factors at play. The age makeup of the established population will play a large role in future population growth or decline.
What are the factors that determine population growth?
When predicting a country’s future population growth, we often discuss factors like the fertility rate and mortality rate. While these determinants play a critical role in population growth rates, it’s important not to overlook population momentum – the additional growth a population experiences after the fertility rate falls to replacement levels. Similar to Marvel’s supervillain character, the Juggernaut, once populations start moving, they do not easily stop. In this blog, we will explain why this phenomenon happens, and examine countries where population momentum is playing a critical role.
What is the population of Japan in 2009?
Negative population momentum can be seen in models of Japan’s projected population. Japan reached its peak population of 129 million in 2009, despite its TFR remaining below replacement levels since 1985. The inertia from Japan’s youth entering reproductive years kept the population growing for a few additional decades.
How many people will be in Japan by 2049?
However, with TFR far below replacement levels for 35 years and its peak population behind it, Japan’s population is expected to fall below 100 million people by 2049. Even if Japan’s TFR rebounded, it would take decades to turn the shrinking population into a stable model without drastic changes to immigration policy.
How can negative population momentum be mitigated?
Negative population momentum on a national scale such as Japan can be mitigated with changes to immigration policy. If more young people from around the world are ushered into Japan, their age structure and overall population trends could quickly stabilize.
When will China's population peak?
In fact, China’s population is expected to peak sometime in the 2030s, despite decades with a total fertility rate (TFR) far below replacement level. At the start of the one-child policy, 36% of the Chinese population was under 15 years of age and hadn’t yet reached their reproductive years – a significant percentage of the overall population.

With respect to lowest-low fertility countries (for example in Europe ), ...
Why does population momentum occur?
Population momentum occurs because it is not only the number of children per woman that determine population growth, but also the number of women in reproductive age.
