2. Population
Population is a group of similar species living
in a certain place at the same time
Population is the interaction between the
organisms that causes a population to change.
DEMOGRAPHY – is the science that deals with
age, size, distribution, and number of births and
deaths of human population.
4. Characteristics of Population
1.
Size
Pertains to the number of individuals in a population
Factors that Contribute to the Size of a Population:
1. Natality – the number of species that are born
2. Mortality – the number of species that die
3. Migration – the transfer of species from one place to another
a. Immigration – the number of species that entered the land.
People who move to a place add to the population.
b. Emigration – the number of species that leave the land lessen
the population of that place.
5. Characteristics of Population
2. Density
Refers to the number of persons living per square
kilometer which can be computed as:
Population density increases when the factors are
favorable to the population and decreases when they
are unfavorable.
Population density may vary from year to year and is
determined by external factors
6. Characteristics of Population
3. Distribution
The arrangement of the individuals of a population
within a particular space.
Random Distribution – There is no specific order in
random distribution, the organism is spread throughout the
area without an over-all pattern.
Uniform Distribution – the organism are evenly distributed
over an area.
Clumped Distribution – the organism are concentrated in
an area. It may offer the population protection from enemies.
7. Reasons why Filipino have an Immense
Growth of Population
Tradition of having big families
Question of Gender
The male macho image
Educational background
Unsatisfactory/Ineffective family relationship

8. Problems on Population Growth in the
Philippines
Environmental problem
Increase in population means increase in waste materials thrown in the
environment and there is a greater degradation and deterioration of nature.
Social problem
Over population may result to prostitution, drug addiction, crime,
juvenile delinquency, suicide and others due to lack of opportunity to
have a nice stable job because of too much competition.
Economic problem
The economists consider population growth a problem because it hinders
the country’s effort to satisfy the needs of the citizens.
Educational problem
It is a problem when the Philippine government cannot provide enough
education, classrooms, school facilities, education materials even qualified
teachers.
9. Problems on Population Growth in the
Philippines
Health problem
The health condition of the people is being affected due to adverse
conditions: prevalence of disease, epidemics and undernourishment.
Spiritual and moral problem
Due to overpopulation, people become materialistic and liberalistic.
The morality and spirituality of young generation seem rapidly
declining.
Problem of food supply
Overpopulation leads to problem on how to provide for people’s
basic needs.
Problem of destruction of nature
Population growth may result to fast deteriorating environmental
resources, such as virgin forest.
Agricultural lands are converted into industrial sites, biodiversity
becomes endangered.
10. Birth rate refers to the number of children
who are born. This is usually the dominant
factor in determining the rate of population
growth. It depends on both the level of fertility
and the age structure of the population.
Death rate is the number of persons who died.
13. Age structure — the proportion of the population in each
age class. It influences whether a population will increase
or decrease in size.

As the population increases, problem multiplies
such as problems about food, housing,
employment, peace and order, health, and others.
16. Projected Philippine Population
Philippine population would continue to grow,
increasing from 76.5 M, as of the latest population
census conducted in May 2000, to 141.7 M in 2040
The population is projected to grow by 1.95% in the
2005-2010 periods, from 85.3 M in 2005 to 94 M in
2010
In 2010, CALABARZON would have 11.9 M people,
while NCR, 11.6 M. By 2040, CALABARZON would
have 18.5 M and Central Luzon would have 15 M.

19. Impact of Population in the
Developing Country
There will be an increase in working age population
and this will give the country an opportunity to
develop its human capital.
The government and private sector will have to start
planning for their education and health needs as well
as for their employment.
