demographic transition model

1.Demographic transition model use - shows the changing relationships between birth rates, death rates, and population growth over time

2.Demographic transition model represents - the general trend in countries rather than the current situation

3.Demographic transition model explains - what happens to birth rates, death rates and over population growth over many years

4.Stage 1 birth and death rates - high

5.Stage 1 total population - low

6.Stage 1 changes in population factors - war, famine, disease

7.Stage 1 high birth rate causes - lack of birth control (access) and education

8.Stage 1 high death rate causes - disease, famine, poor diet, poor hygiene, bad medical services

9.Stage 1 characteristics - low level technology, irregular food supplies, uneducated population, agriculture based society

10.Stage 2 characteristics - population explosion (due to difference in birth and death rate) , population starts to grow (early expanding) and tech improves

11.Stage 2 birth rate - remains high (people prefer larger families)

12.Stage 2 death rate - begins to make a significant drop due to improvements in medicine, diet, services, infrastructure and less wars

13.Stage 2 life expectancy - increases due to improvements and causes the reduced death rate

14.Stage 3 (late expanding phase) death rate - stable

15.Stage 3 birth rate - drops due to urbanization and industrialization, large families are no longer beneficial (less farm work) and greater focus on jobs

16.Stage 3 total population - starts to level out as the population growth rate decreases

17.Stage 4 - low stationary phase

18.Stage 4 negative natural increase -leads to a smaller population, birth rate can slowly drop below the death rate

19.Stage 4 birth and death rate - stable, birth rate is just above replacement level (small families become the norm)

20.Stage 5 (declining populations) - birth rates fall below the death rate, leads to a decline and an aging population.

24.Stage 4 shape

25.Stage 5 shape

26.Demographic transition model helps - government planning and decision making, for example pension provisions / necessary incentives
