Q

Many countries exceed the global average
footprint of 2.7 ha per capita.

36
Q

Slow population growth because high birth rates and high death rates which offset each other.

A

Phase 1: The Theory of Demographic Transition

37
Q

Rapid population growth because birth rates remain high but death rates decline because of better sanitation, clean drinking water, availability of food and health care. (What is “cultural lag”?)

A

Phase 2: The Theory of Demographic Transition

38
Q

Stable population growth as the economy and educational system improves and people have fewer children.

A

Phase 3: The Theory of Demographic Transition

39
Q

Declining population growth because the relatively high level of affluence and economic develop encourage women to delay having children.

A

Phase 4: The Theory of Demographic Transition
