WORLD POPULATION

DEFINITION: : _ Population is defined as the number of people living in
an
area at a particular time.
SIZE OF WORLD POPULATION :
-World population estimate[4.5 billion people,1982]
-1990 [5.2 billion people]
-World average growth rate [2.3%]
-By year 2000 [6.2 billion people]
IN TERMS OF CONTINENTS:
-Asia [the most populous];Europe [second];Africa[third];
;North America[fourth];Australia[sixth].
IN TERMS OF COUNTRIES:
-China [most populous,1.3billion people]
POPULATION CONCEPTS

[1]OVER POPULATION:
-Over population is a situation where a country
has more people than its physical and human
resources . Or, -it is a situation where the
population exceeds the available resources of
the country ;if the people are to enjoy highest
possible standard.
[2]UNDER POPULATION :
-Under population is a situation, in which the size of
the population is consider too small to fully utilize
the available resources
Population concept contd
[3]OPTIMUM POPULATION:
-Optimum population is a situation in which
the number of people can be supported by
the available resources in the area ,so as to
achieve the highest possible standard of
living.
[4]POPULATION DENSITY:
-Population density is the number of people
per. Unit area, and recorded as X number of
people per. Sq.km.
Formula: Pop Density = Total Population
land area
Population concept contd



Land Area : Total Population
Population Density
Total Population : Population Density * Land Area.

BIRTH RATE: It is the rate at which children are being giving birth to in a country
otherwise known as natality.

DEATH RATE: It refers to the rate at which people, both adult and children die in a
country otherwise known as Mortality.

GROWTH RATE: This is determined by the rate of birth, death and population
movement in the country [inward and outward].


Formulae:-pop growth=[BR-DR]+[I-E] or BR-DR + NM
BR=Birth Rate, DR =Death Rate, I=Immigration,
E=Emigration , NM=Net Migration.
Population concept contd

AGE AND SEX STRUCTURE: The age structure of a population is a relative
proportion of children, adults and old people in a population.

The sex structure or ratio is a relative proportion of males and females in a
population. Note: Information about age and sex structure is expressed in
form of population pyramids.

DEPENDENCY RATIO: Dependency Ratio means the number of dependants
expressed as proportion or percentage of the working age population
The population of a country is usually divided into two groups. [1] Working Age
population [15 to 65 years old], [2] The Dependants[children below 15 years and
the elderly above 65 years]
FACTORS OF POPULATION DISTRIBUTION PATTERNS

FACTORS OF POPULATION DISTRIBUTION PATTERNS:

Factors of population growth can be broadly classified into physical and
human factors.

[a] Physical Factors: Climate , Availability of water, Relief, Soil, Presence of
mineral resources.

[b] Human Factors: Agriculture, Religious Beliefs/cultural Factors,
Industrial/trade/commerce ,Immigration, Transport network , Improved social
amenities.
PATTERNS OF WORLD POPULATION
DISTRIBUTION
Population is not uniformly distributed through out the world.
The pattern of world population distribution is grouped into three namely
[a]DENSELY POPULATED AREAS:
---Industrial North West Europe
---Industrial North East USA
---Agricultural Monsoon Asia
---The Nile Valley and Delta
[b] MODERATELY POPULATED PARTS OF THE WORLD:
---Cold Temperate Regions of Europe, Asia and other parts of USA.
---Tropical Temperate Grassland of Southern Russia, Prairies [N/America], Sudan savanna belt of West Africa.
---Africa and most parts of South East Asia.
PATTERN OF WORLD POP DISTRIBUTION
CONTD

[C] THE SPARSELY POPULATED AREAS:

Cold Land

Hot Deserts

High Mountains

The thick dense forest.
REASONS FOR RAPID GROWTH OF WORLD
POPULATION
The world population has been growing at a
rapid rate for the past few decades:.
 REASONS FOR THIS ARE;
 [A ] Improved medical care
 [B] Advanced Technology and Industry
 [c] Others: Polygamy, early marriage, Lack of
family planning, Illiteracy, Child bearing,
Traditional function of women.

.
