October 1, 2012: Theories of Population & Population Policies
Concluded Population Growth and Change
Understanding Population Change
Demographic Transition Model
- the model suggests that birth and death rates are independent from
each other—it is easier to change the death rate then the birth rate.
Applicability of the model
- yes the transition is possible—the model is based upon population
variables from western Europe
- how long: time component is not well defined...it varies from location
to location. There seems to be this idea that the length of time is
reduced—which would be positive, because if we were to apply this
model today we would achieve it faster
- the significance of technology transfer? Access to markets: if there
isn’t a fair markets, there is not any room for advances.
- Environment issues—consumption (is there an end?)
- with economic development you have greater level of consumptions
- the relationship between people and the environment—must be
taken into consideration.
Lecture 4: Different Views on Population Growth
Economic View: population growth is seen as something that is
positive, because the relationships—you get more people which leads
to more labour—more production more consumption—prices-->a circle
cycle takes place.
Environmental View: population depends on things that are limited
(water, land, etc.) there is a certain carrying capacity that must be
aware of. Renewable resources can become limited. This view sees the
negative stance—things are limited. Limits are related to the actual
Malthus: We have to understand the context: He was English, a
economist, and his religious views. He had a theory about how there is
a disconnection between your food supply and your population supply.
(Population/Food supply equation). Looks at this through the carrying
capacity idea. He never recognized the technological changes—
industrial revolution. Boserup: Also an economist (agricultural). Post WWII she said there
is a relation between food and population—but not the same as
Malthus’s view, rather she believes that population growth
