Title: Demography of the Country: Demographic Transitions
1Demography of the Country
Demographic Transitions
2Demography
- Â is the scientific study of characteristics and
dynamics pertaining to the human population. - The characteristics encompassed by this study
include size, growth rate, density, vital
statistics, and distribution of a specified
population.
3- Demography requires the study of specific
information that may be gathered from a
population census or vital statistic records.
census
4- Demographers- People who study and record this
information -
- - must know both how to scientifically obtain
information and how to interpret it relatively.
5- Demography is widely used for various purposes
and can encompass small, targeted populations or
mass populations. - -Governments use demography for political
observations - -Scientists use demography for research
purposes, and businesses use demography for the
purpose of advertising. - -In real estate, demography is employed to give
clients an overview of specific neighborhoods.
6The total number of people in a society is
determined by three variables
Deaths
Migration
7- Births add to the total population
- Deaths subtract from the population
- Migration
- immigration- adds to the population
- emigration- departure of people from a
society - (also called out-migration)
8Demographic Transition (DT)
- Â is a model used to represent the transition from
high birth and death rates to low birth and death
rates as a country develops from a pre-industrial
to an industrialized economic system. - The theory is based on an interpretation
of demographic history developed in 1929 by the
American demographer Warren Thompson (18871973)

10The transition involves four stages, or possibly
five
- In stage one, pre-industrial society, death rates
and birth rates are high and roughly in balance.
11- In stage two, that of a developing country, the
death rates drop rapidly due to improvements in
food supply and sanitation, which increase life
spans and reduce disease.
12- In stage three, birth rates fall due
to access to contraception, increases in
wages, urbanization, a reduction in subsistence
agriculture, an increase in the status and
education of women, a reduction in the value of
children's work, an increase in parental
investment in the education of children and
other social changes. Population growth begins to
level off.
13- During stage four there are both low birth
rates and low death rates. Birth rates may drop
to well below replacement level as has happened
in countries like Germany, Italy, and Japan,
leading to a shrinking population, a threat to
many industries that rely on population growth.
14- The first census in the Philippines was founded
in 1591, based on tributes collected. Based on
this tribute counting, there were about 666,712
people in the islands.
15- In 1799, Friar Manuel Buzeta estimated the
population count as 1,502,574. - However, the first official census was conducted
only in 1878, when the population as of midnight
on December 31, 1877 was counted. This was
followed by two more censuses, namely, the 1887
census, and the 1898 census. The 1887 census
yielded a count of 6,984,727, while that of 1898
yielded 7.832.719 inhabitants.
16BIRTH RATE
- The crude birthrate of a population is the number
of babies born each year for every 1000 members
of the population or, alternatively, the number
of births divided by the total population, times
1000. - Crude birthrate (CBR)

19Death Rate
- The crude death rate of a population is the
number of deaths each year per 1000 people, or
the number of deaths divided by the total
population, times 1000 - Crude death rate (CDR)
