Demography of the Country: Demographic Transitions

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.

• 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.

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)
