Key Notes
Chapter-2
The World Population (Distribution, Density and Growth)
Listof the Lesson:
General, patterns of population distribution in the world, density of population, factors
influencing the distribution of population, population growth, trends in population growth,
doubling time of world population spatial pattern of population change, impact of population
change, demographic transition, population control measures.
General:
• People are real wealth of the country
• Country is known by its people
• Pop of the world is uneven
“Asia has many people where people are few and few places where people are very many”.
Patterns of Population Distribution
• Population Distribution refers to “the way the people are spaced over the earth surface”.
• 90 % of people are living in 10% of its land. 10 most popular countries (China, India, USA,
Indonesia, Brazil, Pakistan
• Cis Bangladesh Japan and Nigeria) contribute 60% of population.
Density of population:
Ratio between land and people,
Population
Measured in persons per SQ. km Density =
area
• High Density Areas: (more than 200persons/sq km) NE USA, NW Europe, S, SE, and E Asia
• Low Density Areas (less the 1 person / sq km) hot and cold deserts, low latitude areas
• Medium Density: (11-50 persons /sq.km) other than above two areas
Factors influencing the distribution of population
• Geographical Factors
(a) Availability of water,
(b) land forms,
(c)climate,
(d) soils
• Economic Factors
(a) Minerals,
(b) urbanization,
(c) industrialization
• Social and Cultural Factors
(a) Religious factors,
(b) social and political unrest,
(c) border terrorism,
(d) govt. policies
