The number of deaths per 1000 of the population per year.
What factors need to be present for a stable population?
The Birth rate & Immigration and Death rate & Emigration have to be the same.
What factors need to be present for a growing population?
The Birth rate & Immigration needs to be higher than the Death rate & Emigration.
What factors need to be present for a falling population?
The Death rate & Emigration need to be higher than the Birth rate & Immigration.
Why has the world population exponentially increased since the industrial revolution?
We created medicine and vaccines to stop people from death by disease, and ramped up our food production so we donβt starve.
What are the 3 main necessities of life?
Food, water, and energy.
What are the side effects of our exponential growth?
We are using so many natural resources that the world may not be able to support us - we are experiencing climate change.
What is the current world population?
7.7 billion.
Why is the population decreasing in some countries?
Countries such as Japan and Germany have an aging population, where women do not have many babies and the elderly dependent population slowly dies.
Why does female empowerment correlate with a lower birth rate?
When women are empowered, they pursue education and have a much bigger role than just raising and having children. They put higher education and jobs over having children.
Is the world population expected to continue increasing forever?
No, the 11 billionth human is not expected to be born, as women worldwide get better rights and have less children.
What is an LEDC?
A Less Economically Developed Country.
What is an MEDC?
A More Economically Developed Country.
Why do LEDCs have a far quicker growing population?
Women are not as empowered, and have more children. The child mortality is higher and women have more children. However, this is changing.
What is a census?
When a country asks questions about people in each household, to adjust how they use their resources.
When is the world population projected to reach 8 billion?
2025 according to UN
When is the world population forecasted to reach 10 billion?
2083 according to UN.
How does a high infant mortality impact the birth rate?
Many children die to preventable diseases, which encourages people to have more children in the hope that they survive, increasing the birth rate.
How does the emancipation of women impact the birth rate?
As society empowers women, they break free of the bounds that tell them to stay at home and care for children. They are encouraged to stay in education and pursue a birth rate, so their first priority is not to have children.
How does health care access impact the death rate?
Less people die from disease that could be prevented by vaccines and medicine.
How do diseases such as HIV impact death rate and the economy?
Lots of people die from the disease, and many who have the disease cannot work and produce money for the economy.
What is contraception and how does it impact birth rate?
Contraception are ways to prevent a woman getting pregnancy. When women have access to contraception and are educated about it, accidental babies being born are less of an issue.
How can government policies strengthen or reduce the population
In countries where the fertility rate is too low, government policies can be implemented to increase population by giving benefits to those with more children.
In countries with too high of a population, the opposite can be done.
How can family planning decrease birth rate?
If rural areas are having too many children, the people can be taught that it is easier to support a family with less children.
What are some things that can lead to an increased death rate?
War or conflict, disease, drugs & alcohol, sexually transmitted disease, famine.
Do LEDCs or MEDCs have a higher birth rate?
LEDCs have a higher birth rate.
What is natural increase?
When the birth rate is higher than the death rate.
Define emancipation.
When a discriminated group is given equal rights.
Why is reducing birth rate important for our planet?
Our planet has limited natural resources, and our world cannot support our ever increasing population.
Define infant mortality.
The number of deaths under one year of age, per year, per 1000 live births.
Why has infant mortality reduced?
Vaccines that stop preventable disease.
What does the DTM stand for?
Demographic transition model.
What is the DTM?
A model which shows the way that population growth can be divided into four (or 5 now) stages that show how birth and death rates change over time, based on what happened in Europe and NA.
What is the birth rate, death rate, and natural change like in stage 1 of the DTM?
The birth rate is high, so is the the death rate. There is a stable or slow natural increase, and the population is low.
What is the birth rate, death rate, and natural change like in stage 2 of the DTM?
The birth rate is still high, but the death rate falls rapidly. There is a rapid increase in natural increase.
What is the birth rate, death rate, and natural change like in stage 3 of the DTM?
The birth rate is falling rapidly, the death rate continues to fall more slowly, and the natural increase slows down.
What is the birth rate, death rate, and natural change like in stage 4 of the DTM?
The birth and death rates are low, the natural increase falls and comes to a halt.
What is the birth rate, death rate, and natural change like in stage 5 of the DTM?
The birth rate falls further, and becomes lower than the death rate. The death rate rises as elderly die, and there is a lowering natural increase. (we do not know this for sure as not many countries are in stage 5)
What are the 5 stages of the DTM?
Stage 1 (High fluctuation), Stage 2 (Early expanding), Stage 3 (Late expanding), Stage 4 (Low fluctuating), and Stage 5 (Natural decrease)
Why is there high fluctuation in stage 1 of the DTM?
Due to disease, famine, and war.
What are some examples of places in stage 1 of the DTM?
In traditional rainforest tribes in places such as Indonesia, Brazil, and Malaysia where people live separately from the outside world.
What are some examples of places in stage 2 of the DTM?
In some of the poorest and most underdeveloped countries in the world such as Afghanistan, or a lot of Sub-Saharan Africa.
What are some examples of places in stage 3 of the DTM?
In countries like Nigeria, India, and Mexico, the death rate is much lower than the birth rate, which falls due to changing social conditions.
What are some examples of places in stage 4 of the DTM?
In more developed countries like the USA, Singapore, and Brazil.
What are some examples of places in stage 5 of the DTM?
In more developed countries such as Germany, Japan, and Portugal.
Which stage of the DTM is the most economically sustainable and why?
Stage 4 of the DTM is the most economically sustainable because women work as much as men in high paying jobs, more taxes being paid to the government - and with there still being a healthy fertility rate there is a sustainable population.
What is the problem of being in stage 5 of the DTM?
There is in general, a growing elderly dependent population in stage 5 of the DTM, and the few young people have to work. The elderly are a strain on the young who have to use their time to take care of them, making economic growth difficult.
What are the problems with the DTM?
- The DTM does not take into account migration, which can increase or decrease economic development.
- The original DTM is outdated in some aspects.
How is population growth beginning to slow down?
The average number of babies have been decreasing, due to family planning, education, and contraception.

1.43.
What is the percent of women who have 1 child, and the percent of women who have no children? IN ITALY.
25% of women have only 1 child, and 25% have none. This makes the YDP very low, so once the elderly retire they wont be replaced.
Why is the death rate in Italy higher than the birth rate in Italy?
For one, Italy has a low birth rate. People donβt die of disease but of old age.
Why does Italyβs population increase even with negative natural increase?
Due to immigration. Italy welcomes asylum seekers and immigrants.
