Population and Development
Discussion pointWhat is the pattern of population growth in the world?How does population growth stimulate the development? Briefly explain in terms of Keynes and Lewis model.What are the causes of population growth? Will population continue to increase in the world?What are the consequences of increasing life expectancy and aging in the developing world?Why will the population of underdeveloped countries be higher in 2050? Why will it decrease in Europe and other developed countries?What are the demographic characteristics of Bangladesh? Case studies: Causes of population growth in Bangladesh and Population as asset or liability in Bangladesh
Population Growth Was Very Slow in the Earlier Years of Human Existence, but Has Accelerated in the Past 250 Years

WORLD POPULATION OUTLOOK 1950-2050
Total population 2010 is 6.90 billion and for 2050 will reach 9.08 billionIn spite of higher population for the future, the growth rate of the population is expected to fall due to the decline in fertility rate and the toll taken by the HIV/AIDS pandemic in some countries.However, the death rate declined and the causes of death changed towards Cancer and Cardiovascular diseases.Fertility rate decline – family planningIncreasing population but decrease in average annual growth rate. e.g. 1.1% in 2009, but 0.43% to 0% in 2050

No population explosion after 2050!!
Population Growth Inhibits Development
Population stabilizes at the level of subsistence
“Whenever human beings obtain more than mere subsistence, their numbers go up until everybody is back at the level of subsistence”- Malthus
Population growth and Development
Population Growth Stimulates Development
• Creation of “Effective Demand”
• Supply of labour at a cheaper wage
Keynes and Lewis content population growth as stimulating development through -
During 18 th and 19 th Centuries rapid population growth in developed world contributed to steady economic growth predicted by Keyes and Lewis
POPULATION OUTLOOK BY REGION 1950-2050
World population growth will be concentrated in developing countries for the foreseeable futurePopulation for Asia, Africa, Sub Saharan Africa, Middle East, North America and South America will increase substantiallyPopulation for European countries and Former Soviet Union tends to fall for the foreseeable futureNot much different for the population for Oceania and Baltic region
Europe is the only world region projected to decline in population by 2050.

Ageing and related problemThe world's elderly population (60 +) is the fastest growing age group. Population ageing is a global phenomenon that is now occurring fastest in low and middle-income countries. By 2050 about 80% of the elderly will be living in developing countries With the increase in the life expectancy of the world population ageing is now a global issue. Elder abuse is on the increase as the social dynamics change. physical, psychological, emotional, financial due to neglect.
Ageing and related problemImpacts of an Ageing population:
-Increase in the dependency ratio -Increase government spending on health care and pensions -Fall in productivity and growth of the country -Shortage of labor force -Changing sectors within the economy
Government responses to an ageing population: -Raise the retirement age -Increase the importance of the private sector in providing pension
and health care -Increase tax to pay for pension cost.

The historical trend of population growth rate suggests that the estimated population of 17
million in 1700 took 230 years to double in 1931.
The second doubling took only 43 years, i.e., the population of 1931 doubled its size in 1974.
Third doubling occurred in just about 30 years in 2005.
