2. DEMOGRAPHY AND POPULATION
Population refers to the
total number of person
inhibiting a country, city or
any district. It also deals
with the observable and
measurable data.
Demography is the study of
the size and make-up of
the human population and
how it changes over time.
3. The main sources of demographic
data are:
• The population census, with data on age, sex, occupation,
employment status, and migration.
• Vital registration statistics like birth, death, and marriages.
• Sample or special surveys on households.
• Data gathered and processed by government agencies
4. MATHUSIAN
THEORY OF
POPULATION
By: Thomas
Robert
Malthus
According to his “Essay on the Principle of
Population”, because of the strong attraction
between the two sexes, the population could
multiply rapidly and, resulted to increase of
reproduction faster than food supply.
Also, as the population grows bigger, food
production would be insufficient and most likely,
famine and overcrowding would cause widespread
suffering and disease and an increase in death
rate, which is nature’s check on over population.
He suggested that an alternative is to postpone
married until a much later age so that birth rate
may be decreased
5. MATHUSIAN THEORY OF POPULATION
Two solutions:
Positive checks to
overpopulation by increasing the
death rate; which include war,
famine, pestilence, and disease.
Preventive checks to prevent
overpopulation by limiting the
number of live births; which
include abortion, infanticide,
sexual abstinence, delayed
marriage, and contraceptive use
6. PROCESS IN POPULATION CHANGE
Fertility - It is the ability to produce offspring. It indicates the rate at
which babies are born. According to the demographers, women have a
potential for bearing age at age of 15 to 50. The fertility rate of a
community was affected by some factors such as weather,
environment, religion and societal norms about children and marriage.
Life expectancy - The average number of years a persons is expected to
live from time of birth. It is hard to determine this accurately because
local statistics on birth and death rates are incomplete and inadequate
because some data are not registered.
7. PROCESS IN
POPULATION
CHANGE
• Mortality- The rate of death in population. A
population with many old people will naturally
have a higher death rate than a comparatively
young population. It is also assumed that
because women live longer than men, a
population with many women will have lower
death rate.
• Migration- The movement of people for
permanent residency. It includes immigration,
movement into an area, while emigration is
movement out of an area. This can be divided
into pull and push factors.
8. BASIS OF
POPULATION
EXPLOTION
• Historical - One of the most important
of Spanish colonization in the
Philippines was the propagation of the
Roman Catholic. Since, the church does
not favour birth control. There is a high
rate of population growth.
• Sociological - The men and women feel
ashamed to submit in artificial methods
of family planning.
• Geography - The rate of population
growth in the rural areas is significantly
higher than that in the urban.
9. BASIS OF
POPULATION
EXPLOTION
• Economic -In rural areas, the perception of
some people that children serves as their
economic assets. They think that a big family is
better than a small one because children can
earn a livelihood for the family.
• Anthropological - It assumed that basis of
population explotion is the Filipino values,
belief system, customs and traditions. The
extended family expected that the couple to
have a number of children during the
marriage. One is not surprised to hear remarks
like, “bakit wala pa?”, if the pregnancy does
not takes place after marriage. The husband is
jokingly branded to be “mahina” if his first
child is not followed by another one year after.
