Population Basics
The maximum number of people an area can support.
What is carrying capacity?
The term for the number of births in a year per 1,000 people.
What is Crude Birth Rate?
The stage of the DTM where birth rates remain high while death rates begin to fall, causing rapid population growth.
What is Stage 2?
The term for a government policy that encourages people to have more children.
What is pro-natalist?
Conditions that make people want to leave a place.
What are push factors?
This scholar predicted that population would outgrow food supply, leading to famine and conflict.
Who is Malthus?
The term for the number of people per square unit of land?
What is Population Density?
When a country's birth rate is high and death rate is low, what happens to its population?
It grows rapidly.
What can a sharp narrowing at the base population pyramid tell us about a country's birth rate?
The birth rates are declining rapidly.
The country that implemented a one-child policy other than slow population growth in the late 20th century.
What is China?
The term for people who move from one country to another temporarily to work, without intending to stay permanently.
What are guest workers?
Name one social or economic factor that usually leads to a decline in fertility rates.
Increased education for women, access to contraception, urbanization, or high cost of living.
The type of population density that measures people per unit of arable land.
What is physiological density?
The term for the average number of children a woman is expected to have in her lifetime.
What is total fertility rate?
Why do birth rates begin to decline in stage 3 of the DTM.
Due to increased urbanization, access to family planning, and changing social values.
What is a common strategy used in anti-natalist policies?
providing free contraception or access to family planning services.
The type of migration taht happens in a series of smaller moves, gradually bringing a person to their final destination.
What is step migration?
The term for money that is sent by migrants back to family in their home country.
What are Remittances?
Why might a country have a low arithmetic density but a high physiological density?
Much of the land may be unusable for farming, so that arable land is crowded even if the overall land area is large.
What does a total fertility rate below 2.1 indicate about a country's population?
The population is likely to decline without immigration.
The stage of the DTM is characterized by a declining population and an aging society.
What is stage 5?
Why might a developed country adopt a pro-natalist policy?
To counter population decline, labor shortages, and an aging population.
This is the most common type of migration globally.
What is internal migration?
The model that shows the shift in disease patterns as a country develops, paralleling the demographic transition model.
What is the epidemiological transition model?
A country has an arithmetic density of 45, a physiological density of 600, and an agricultural density of 250. What can you infer about its level of development.
It is likely a less developed country with many farmers per unit of arable land and a small portion of arable land compared to total land area.
A country has a crude birth rate of 10 and a crude death rate of 12. What is its natural increase rate, and what does this mean?
The NIR is -2, meaning the population is decreasing.
The stage of the DTM that is represented by a population pyramid with a rectangular shape, showing low birth and death rates.
What is stage 4?
What is one possible negative consequence of a strict anti-natalist policy?
Gender imbalances, aging population, or human rights violations.
According to Ravenstein, this is the type of area that migrants typically move to.
What are urban areas?
How can an aging population impact a country's economy and social services?
Fewer workers to support the economy, greater demand for healthcare and pensions, and a possible need for immigration to fill labor shortages.
