12. - the quantitative or statistical study of populations
- the study of the size, territorial distribution and
composition of a population, changes therein, and
components of such changes, which may be
identified as natality, mortality, territorial movement
(migration), and social mobility (change of social
status) (Hausser and Duncan, 1959)
13. According to Anderson, demography studies the following:
• Population Size
• Population Growth or Decline
• Population Process
• Factors Related to Population
Processes
• Population Distribution
• Population Structure
• Population Characteristics
14. Population Size
The number of people in a country, a state, a city, a region, or the
world at a given time.

19. Fertility is the ability to conceive children or young.
The worldwide fertility
rate is around 2.4
children per woman.
Here are the 10 countries with the highest
fertility rates:
Niger (6.9)
DR Congo (5.9)
Mali (5.9)
Chad (5.7)
Angola (5.5)
Nigeria (5.4)
Burundi (5.4)
Burkina Faso (5.2)
Gambia (5.2)
Uganda (5)

21. Mortality is the state of being subject to
death.
NOTE: All 2020 and later data are UN projections and DO NOT include any impacts of the COVID-19 virus.
23. World Infant Mortality Rate 1950-2021
The current infant mortality rate for World in 2021 is 27.334 deaths per 1000 live births, a 2.29% decline from 2020.
The infant mortality rate for World in 2020 was 27.974 deaths per 1000 live births, a 2.24% decline from 2019.
The infant mortality rate for World in 2019 was 28.615 deaths per 1000 live births, a 2.19% decline from 2018.
The infant mortality rate for World in 2018 was 29.256 deaths per 1000 live births, a 3.09% decline from 2017

24. Excess mortality: the Coronavirus pandemic
(COVID-19)
Excess mortality is a term used in epidemiology and public health
that refers to the number of deaths from all causes during a crisis
above and beyond what we would have expected to see under
‘normal’ conditions.

26. Effect of
Migration
Many countries with less than replacement rate are
also growing due to net migration. When immigration
is greater than emigration, this increases numbers of
people directly but it can also increase the birth rate.
This is usually because migrants tend to be younger
people of working age, so are more likely to have
children than the average for the existing population,
and because in some cases, they come from countries
or cultures with traditionally higher fertility rates and
family sizes.
27. Factors Related to Population Processes
These are the diseases and socioeconomic
characteristics related to mortality, family
formation, labor force participation, government
policies related to fertility, the difference in
income and opportunities in various areas, war
and immigration policies, and economic
conditions motivating migration.
28. Population Distribution
geographic distribution, such as among states or
between rural and urban areas.
An example of population distribution is the fact that
China’s natural physical conditions resulted in uneven
population distribution. There is a huge contrast in the
number of people living in eastern China compared to
the distribution in the western part of the country.
29.
30. Population Structure
This is the age and sex composition, the growing
proportion of the population at advanced ages, the
sex ratio at birth, and the increasing proportion of
the population that is female with increasing age.
This is also defined by the organization of genetic
variation and is driven by the combined effects of
evolutionary processes that include recombination,
mutation, genetic drift, demographic history, and
natural selection.
31.
32. Population Characteristics
education, income, labor force participation,
marital status, and race or an ethnic group
membership – anything that has a value for each
member of the population and does not have
the same value for everyone.

35. Aggregate Approach
This is where the importance of population
processes comes in. The components of
population change, such as the roles of births,
deaths, and migration in population size, are
dealt with in this approach. It deals with
macrosocial demographic processes. It studies
how the levels of child-bearing, mortality, and
population movement impact the growth or
decline of a population. This scientific
knowledge would lead scientists and concerned
agencies to deal with the situation by
developing what we know today as
contraceptives.
36. This approach investigates why people have children, their
motivations, or the factors that led them to such a
decision. this approach acknowledges that behavior not
only influences decisions leading to natality or birth rates,
the number of annual births per one thousand people; it
also affects mortality or death rates, the number of annual
deaths per one thousand people. Anderson argues that
although most of us would wish to live longer, decisions to
cultivate habits that tend to shorten human life explain why
the mortality rate is sometimes high. Vices such as cigarette
smoking, alcohol consumption, and drug addiction have a
telling impact on one’s mortality.

behavioral Approach
