Q

the emergence of early and modern agriculture allowed more people to be fed for each unit of land area farmed.

A

Second

17
Q

the development of sanitation systems, antibiotics, and vaccines helped control infectious disease agents.

A

Third

18
Q

– is the actual level of reproduction of a population per individual, based on the number of live births that occur.

A

FERTILITY

19
Q

also known as birth rate is the total number of live humans births per 1,000 population divided by the length of a period in years.

A

FERTILITY RATE

20
Q

also known as death rate is a measure of the number of deaths in particular population, scaled to the size of that population per unit of time.

A

MORTALITY RATE

21
Q

– the act of someone coming to live permanently in foreign country

A

IMMIGRATION (INTO)

22
Q

– leaving own country to settle permanently to another country.

A

EMIGRATION (EXIT)(OUT)

23
Q
  • is the average number of children born to each woman, over the woman’s lifespan, in a population.
A

TOTAL FERTILITY RATE

24
Q

-It is an accelerating pattern of increasing population size

-According to Malthus model once the population size exceeds available resources, population growth decreases dramatically.

A

EXPONENTIAL GROWTH

25
Q

Birth rate and death rates drop to low

A

Stage 4

26
Q

birth rates are higher than death rates.

A

Stage 3

27
Q

As a country develops, medical advances are made such as access to antibiotics and vaccines. Sanitation improvements, such as proper waste and sewage disposal, and water treatment for clean drinking water also progress. Food production also increases.

A

Stage 2

28
Q

is the preindustrial stage. In Stage 1 both birth rates and death rates are high. The high death rates are because of disease and potential food scarcity.

A

Stage 1

29
Q
  • shows the changes in the patterns of birth rates and death rates that typically occur as a country moves through the process of industrialization or development
