Demographic Transition?
Ans. This theory explains 3 staged model of demographic transition:

Stage(iii) Low birth rate,low death rate, stable or low growth rate -example Japan.
Classify the world into various region on the basis of population density
Ans.1 Areas of high Density:
(I) Monsoon Asia,South and South East Asia.

2: Areas of Medium Density
(i)Asia
(ii)Europe
(iii)U.S.A, Australia.
(iv)Africa, South America.

Patterns of population distribution and density of population help us to understand the demographic characteristics of an area.
The density of population is usually measured in per square kilometer.
When we found more than 200 person on every square kilometer then an area will be considered as highly and densely populated.
High rainfall Zone near the equator has very low density of population.
Availability of water is the most important factor that attract the human in habitation in a particular area.
Availability of Mineral wealth is responsible for high density of population found in Katanga Zambia located in Africa.
Kobe Osaka region in Japan is highly populated due to presence of industries.
Mediterranean region is more populated due to pleasant climate.
Mega cities are more populated due to good civic amenities and employment.
The population growth and population change refers to the change in number of inhabitants of a territory during a specific period of time.
Mortality rate of a region mainly controlled by demographic structure, social advancement, level of its economic development etc.
Better job opportunities, peace and stability, security of life’s are the pull factors of migration.
Poor living conditions, political terminals, epidemics are the push factors of migration.
Population grown rapidly during the 16 and 17 century because expansion of World Trade during 16 and 17 century is an important cause of it.
Technological advancement factors helps in the reduction of birth rate and provide at a stage for accelerated population growth.
It took almost 12 years to rise population from 5 billion 6 billion.
In the developing countries the birth rate is extremely high as compared to death rates, need for children to go out and work to bring in income for the family, lack of availability and knowledge of contraception and family planning.
Negative type of correlation we found between economic development and the population growth.
Migration may be interpreted as a spontaneous effort to achieve a better balance between population and resources.
The following statements are the true about the population change: increase of population causes depletion of resources, population decline causes under development of resources, the resources that had supported earlier are now insufficient to maintain the population.
HIV/AIDS reduced average life expectancy in Africa and some part of CIS.
Latvia, Estonia, Denmark are the low population growth countries.
Somalia, Albania, Germany are the high growth rate of population countries.
The following are the characteristics of first stage of demographic transition: expectancy is low, people are mostly illiterate and have low level of Technology, people are engaged in agriculture where large families are an asset.
The following are the important characteristics of last stage of demographic transition: the fertility and the mortality decline countably, deliberately controls the family size, the population becomes urbanized and literates.
