DEMOGRAPHY
Subtitle

2. DEMOGRAPHY
 It is the statistical study of human
population.
 examines the size, structure and
movements of populations over space
and time.

3. DEMOGRAPHY
STUDIES THE
FOLLOWING:

4. 1. POPULATION SIZE- The number of people in a
country.
2. POPULATION GROWTH- Changes in the number
of people in a given geographic area over time.

5. 3. POPULATION PROCESSES- Fertility, mortality and
migration.
4. FACTORS RELATED TO POPULATION PROCESSES- disease and
socio-economic characteristics related to mortality,
family formation, labor force participation, government
policies related to fertility.

6. 5. POPULATION DISTRIBUTION- geographic distribution such as
among states or between rural and urban areas.
6. POPULATION STRUCTURE- Age and sex structure.
7. POPULATION CHARACTERISTICS- education, income, labor,
marital status, race and ethnic groups.

7.  Having a child is a symbol of

planting and
harvesting season.

10. URBAN COMMUNITIES
 The poorer districts of urban
centers also tend to have
families with more children

small family business depends
on how many of their
members can be hawking their
wares on the street.

11.  Urbanized, educated and
professional families with
two incomes, however
desire just one or two

12. urban

necessarily because of having a more
children in every families.
 It is rather the combination of the natural
outcome of significant migration to the cities
by people who seek to have work or jobs.

13. THE PERILS OF
OVERPOPULATION

14. THE PERILS OF OVERPOPULATION
 Development planners see urbanization and
industrialization as indicators of a developing
society, but disagree on the role of population
growth or decline in the modernization.

15. THOMAS MALTHUS
 British scholar who
brings back the idea
that “population
growth will inevitably
exhaust world food
supply”.
“AN ESSAY ON THE PRINCIPLE OF POPULATION”

16. PAUL R. EHRLICH
(American biologist)
 It will bring global
environmental
disasters that would
lead to food shortage
and mass starvation.
“THE POPULATION BOMB”
1960

17. RECOMMENDATIONS TO AVOID MASS
STARVATION:
 Bizzare or Chemical Castration
 Policy Oriented- taxing an additional child
and luxury taxes in child related products.
Monetary Incentives- paying of men who
would agree to be sterilized after two
children.

18. RECOMMENDATIONS TO AVOID MASS
STARVATION:
 By limiting the population, vital resources
could be used for economic progress and not
be diverted and wasted to feeding more
mouths.
 This argument became the basis for
government “population control programs”.

19. VASECTOMY
Vasectomy is a form of male
birth control that cuts the

 (It is sometimes called
"tying the tubes.")

21. MOST POPULATED
COUNTRIES
