4 WORLD POPULATIONDEFINITION: : _ Population is defined as the number of people living in anarea 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]-India[second, 1.0 billion e.t.c]
5 POPULATION CONCEPTS OVER POPULATION: -Over population is a situation where a countryhas more people than its physical and humanresources . Or, -it is a situation where thepopulation exceeds the available resources ofthe country ;if the people are to enjoy highestpossible standard.UNDER POPULATION :-Under population is a situation, in which the size ofthe population is consider too small to fully utilizethe available resources
6 Population concept contd 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. 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
7 Population concept contd Land Area : Total PopulationPopulation DensityTotal 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 + NMBR=Birth Rate, DR =Death Rate, I=Immigration, E=Emigration , NM=Net Migration.
8 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 populationThe population of a country is usually divided into two groups.  Working Age population [15 to 65 years old],  The Dependants[children below 15 years and the elderly above 65 years]
9 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.
10 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.
11 PATTERN OF WORLD POP DISTRIBUTION CONTD [C] THE SPARSELY POPULATED AREAS:Cold LandHot DesertsHigh MountainsThe thick dense forest.
12 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.
13 ASSIGNMENT FOR WEEK 1  Define population  Write short notes on any five population concepts. Calculate the population density of a country “X” whose population is 12,000,000[m] and Land Area is km sq.Explain four physical and four human factors that affect population distribution patterns.Draw the world population map on a cardboard paper.
