Population and Migration Flashcards
What is natural increase?
Difference between birth and death rates.
What is exponential growth?
Pattern where growth rate constantly increases in a J shape.
What is the difference between dense and sparse populations?
Dense has a high concentration of people, sparse has a low one.
What does NIC stand for and what are some examples of NICs?
Newly Industrialising Countries. For example India, China and Singapore.
What causes high birth rates in LEDCs?
Limited contraception, few women’s rights, dropping out of school, early marriage, the need for big families.
What causes high death rates in LEDCs?
Contaminated water, no access to hospitals, poor infrastructure (prone to damage; could trap, collapse, break on someone), dropping out of school w/o needed knowledge, unhealthy diet.
The global population distribution is very uneven. True or false?
True.
Why might weather cause counties to be sparsely populated?
People that work outside like farmers need good weather. Coldness prevents growing, hotness makes the soil thin. They will move somewhere that is more suitable.
Why is global population increasing?
Better living conditions and medical care. There is a natural increase happening.
What does DTM stand for and what is it?
Demographic Transition Model explains birth and death rate and global population patterns through time.
What happens on Stage 1 of the DTM?
High fluctuating, birth rates are high, death rates are high.
What happens on Stage 2 of the DTM?
Population increase, birth rates are still high like Stage 1, death rates start to decrease.
What happens on Stage 3 of the DTM?
Population increase, birth rates start to decrease a lot, death rates continue to decrease.
What happens on Stage 4 of the DTM?
Low fluctuating, birth rates stay low, death rates stay low.
What happens on stage 5 of the DTM?
Ageing and decline, birth rates are very low, death rates rise slightly.
