Faster population growth

19
Q

Demographic Transition

A

Describes the changes in population size, the structure caused by changes in birth rate, death rate and by migration

20
Q

Urbanization?

A

The increase in the proportion of people living in towns and cities vs rural areas

21
Q

Birth Rate?

The number of births per thousand per year

22

The number of deaths per thousand per year

23
Q

Growth Rate?

A

The rate or speed at which the number of organisms in a population increase/ decreases

24
Q

Infant Mortality and importance as a demographic stat?

A

The death of a baby that occurs between the time of birth and one year. It is used as a measure of the health and wellness of a community.

25
Q

Average Income meaning?

A

The income that is earned by a person in a given area for a given period of time.

26
Q

How can an age structure diagram be used to predict population growth by shape?

A

Curves inward with a point at the top - Rapid Growth
Equilateral Triangle Shape - Slow Growth
Equilateral Triangle with Rectangle as the base - Slow Growth/ Stabilizing
Fingernail Shape- Stable

27
Q

What is GDP and why is it important as a demographic stat?

A

Gross Domestic Product ; it is an indicator of how healthy the economy is and generally the access to resources the population has

28
Q

What is the ecological footprint and why is it an important demographic stat?

A

The available land and sea needed to provide the renewable resources ad population uses and the waste it produces. It is a measure of how sustainable a population lifestyle is in a given area and generally Earth’s biocapacity.

29
Q

As a country develops, what are some positive changes that happen for people living there?

A

Better health care and increased life expectancy, better technology and education

30
Q

As a country develops, what are some negative effects on the environment?

A

Overconsumption, overpopulation, pollution, burning fossil fuels, deforestation

31
Q

How is population growth different between developed and developing countries?

A

The population in developed countries is generally more stable or shows a decline in growth rate. The population in developing countries is growing and the growth rate is larger.

32
Q

How is resource use different between developed and developing countries?

A

Developed countries have much higher levels of resource consumption compared to Developing countries due to larger economies, higher standard of living and industrialization.

33
Q

As a country develops, what are some positive changes that happen to the people living their?

A

As a country develops it gains better healthcare and increased life expectancy, as well as better technology. In the table, the more developed country’s (the US and Germany) have higher life expectancies with the US at 77 years and Germany at 81 years While, in developing countries (Mozambique) has a life expectancy of 60 years. This shows that more developed countries have the medical technology and healthcare to have a high life expectancy unlike developing countries, as they do not have all of the resources to be able to have high life expectancy.
