Unit 2: Chapter 2 Key
Issue 4
What did Thomas Malthus believe
about overpopulation?
The world’s population was
increasing much faster than food
supply.*****
Cont.
Malthus argued that
◦
population
increased
geometrically
◦
while
food supply
increased
arithmetically
.
****
Neo (New)- Malthusians
are people still
influenced by Malthus today.
They believe:
1. Many LDCs have expanded their food
production,
but
they also have more poor
people than ever before.
2. Not only are we using all of the food supply,
but we are also outstripping the energy
supply and other resources like clean air
and fuel.
BELL RINGER:
1.) In what ways could continuing population increase
actually be a good thing? (brainstorm with those around
you)
2.) How does the concept of possibilism relate to Malthus
being wrong?
3.) Referencing the maps/charts on page 73- Where are
the lowest percentages of people using family planning?
What is the most common method in Germany vs. the one
used in China? Nigeria is the most populated country in
Africa- how does this pie chart show that they will
probably remain the most populated for some time?
9.23.16
1.
He had a
pessimistic viewpoint
:
Actual food production has been much
higher than Malthus predicted.******
He thought world’s resources were
fixed instead of expanding but
humans can impact this – possibilism!
He failed to consider technological
innovation.
2.
Contemporary analysts believe population
growth can be positive.
1.
Pop growth could trigger econ. expansion.
2.
Julia Simon: More brains = More good ideas.
3.
Marxist critique
– believe there are plenty of
resources in the world – just need to be shared
between the haves and have nots.
What is contributing to declining
birth rates?
1.
Econ development-
educ and health-care
programs, work for women = lower birth rates.
2.
Distribution of contraception-
rapidly
diffusing around the world.
Some women do not have many rights - so
more children= higher status.
Men see it as a sign of virility.
Religious or political reasons.

Family Planning
1.) Why are the
percentages near D
lower than those near
E?
2.) What event
occurred at C (on both
sides) that would’ve
resulted in a much
lower population?
3.) What happened to
the birth rates at B
(both sides)?
4.) The area around A
indicates that Germany
is in what stage of the
demographic
transition?

What is the Epidemiologic
Transition?
Focuses on
distinctive
causes of
death in
Epidemiologic Transition
Description Example
Stage 1 Pestilence and famine Black Death, 1300s
Stage 2
Stage 3
Stage 4
Epidemiologic Transition
Description Example
Stage 1 Pestilence and famine Black Death, 1300s
Stage 2 Receding pandemics *****Dr. John Snow – geographic mapping contains cholera
Stage 3
Stage 4
Epidemiologic Transition
Description Example
Stage 1 Pestilence and famine Black Death, 1300s
Stage 2 Receding pandemics *****Dr. John Snow – geographic mapping contains cholera
Stage 3 Degenerative and human
created diseases Heart attacks and cancer Stage 4
Epidemiologic Transition
Description Example
Stage 1 Pestilence and famine Black Death, 1300s
Stage 2 Receding pandemics *****Dr. John Snow – geographic mapping contains cholera
Stage 3 Degenerative and human
created diseases Heart attacks and cancer Stage 4 DELAYED degenerative
diseases
Still heart attacks and cancer but life
expectancy longer due to medical advances

Stage 3 Degenerative and human created diseases
Heart attacks and cancer
Stage 4 DELAYED degenerative
diseases Still heart attacks and cancer but life expectancy longer due to medical advances
Stage 5 Possible Reemergence of infectious and parasitic diseases
*****WHY? Evolution, Poverty, Improved Travel – easier to
AIDS
◦
Mostly in LDCs.
◦
CDRs in Sub-Saharan Africa rose sharply in the
1990s because of AIDS.
The Most Lethal Infectious Disease: AIDS
Work on finishing 2.3 and 2.4 guides/notecards (extra notecards on front
desk if needed) and study for the quiz tomorrow!!
Key Issue 2.2 and 2.3 Quiz Hints: Know all vocabulary for 2.2 and 2.3
Be sure to have read through all of 2.2 and 2.3 Know how to calculate NIR given CBR and CDR
NIR FORMULA: ((CBR-CDR)/1000) * 100 = NIR
Know the shape of a population pyramid for a stage 2,3,4, and 5 country Know the CBR, CDR, and NIR for each stage of the demographic transition Be able to calculate doubling time given the initial population, final
population, and time span
