Title: Demography of the Country: Demographic Transitions


1
Demography of the Country
Demographic Transitions

Demography
  •  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.

6
The total number of people in a society is
determined by three variables
  • Births

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)

8
Demographic Transition (DT)
  •  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)

The 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.

16
BIRTH 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)

Death 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)
