the study of population
Demography
several components of population
size, composition, and territorial distribution.
refers to the total number of people inhabiting a particular geographic area at
a specified time
population
Sources of Population Data
Vital Statistics
Census
which consist of information recorded by the government about births, marriages,
deaths, and migrations into and out of a country.
Vital Statistics –
– refers to the periodic head count of the entire population of a country. It includes data such as
age, sex, education, occupation, and residence.
Census
is the difference between the number of births (B) and deaths (D), plus
the difference between immigrants(I)(those who enter a country to establish permanent residence) and
emigrants (E) (those who leave a country permanently), thus the formula GR = (B-D) + (I-E)
Growth Rate (GR) of a society
Theories of Population Growth
Malthus Thesis
The Marxist Perspective
The Neo-Malthusian Perspective
proposed by Thomas Robert Malthus. He believed that the world’s population was
growing more rapidly than the available food supply. He argued that food supply increases in an
arithmetical progression (1,2,3,4,5, etc) whereas population expands by geometric progression
(1,2,4,8,16, etc). According to this analysis, the gap between food supply and population will continue to
grow though time. Even though the food supply will increase, it will not increase enough to meet the
needs of an expanding world population.
Malthus Thesis
Karl Marx strongly criticized Malthus’ views on population. According to Marx
and Engels, food supply is not threatened by overpopulation; technologically, it is possible to produce the
food and the other goods needed to meet the demand of the growing population. For Marx,
overpopulation is not a problem of too many people. Instead, it is a problem of too much poverty. People
are poor because they are exploited by their employers.
The Marxist Perspective
Neo-Malthusians has reemphasized the dangers of overpopulation. To
them, the earth is a dying planet with too many people and too little food (?), compounded by
environmental degradation. Early-Malthusians proposed birth-control methods while Neo-Malthusians
encouraged people to be part of the solution to the problem of overpopulation though “number of child
policy” in order to bring about zero population growth – the point at which no population increases occur
from year to year because the number of births plus immigrants (those who enter a country to establish
permanent residence) is equal to the number of deaths plus emigrants (those who leave a country
permanently).
The Neo-Malthusian Perspective
is a social institution (basic unit of society) found in all societies that unite people in
cooperative groups to oversee the bearing and raising of children.
