  1. Population and Development Koichi Fujita CSEAS, Kyoto University Japan www.AssignmentPoint.com

  2. Long-term Trend of World Population (1) • Basically very slow population growth due to high mortality rate with high birth rate • Malthus’s Principle of Population Population growth is checked by famine, epidemics, war, and so on. www.AssignmentPoint.com

  3. Long-term Trend of World Population (2) • However, there is a strong tendency that Asia became densely populated because of the rice-eating habit and economic prosperity. • Estimate of GDP in the World in the year 1000 (by A. Madison) www.AssignmentPoint.com

  4. Birth rate Natural increase Death rate Time Note: Natural increase is produced from the excess of births over deaths. The Classic Demographic Transition Stage 1 Stage 2 Stage 3 Stage 4 www.AssignmentPoint.com

  5. Demographic Transition • Stage 1 Stagnation of population with high death rate and birth rate. • Stage 2 Due to nutritional improvement and diffusion of hygiene and modern medical technologies, death rate declines while birth rate remains same, resulting in a rapid population growth. • Stage 3 Due mainly to industrialization and urbanization birth rate also starts to decline and population growth rate decelerates. • Stage 4 Stagnation of (or even decrease) of population with low death rate and birth rate. www.AssignmentPoint.com

  6. Differences in experiences of Demographic Transition between Western and Developing Countries • Period from start and end Western: very long --- more than 150 years DCs: short --- about 30-50 years • Population growth rate at the peak Western: relatively low---around 1% per annum DCs: very high ---around 2.5-4 % per annum • Reasons of death rate decline Western: Gradual process with improved nutrition, hygiene, development of medical technologies DCs: Sudden decline due to eradication of tropical diseases such as malariafrom the 1930s. www.AssignmentPoint.com

  8. Why and how birth rate declined in Developing Countries? (1) • TFR (Total Fertility Rate) The average number of children that a woman have over her lifetime. If TFR is more than 2.1, population will increase, and if less than 2.1 population will decrease. Many Developing Countries experienced a rapid decline of birth rate (TFR) in recent years. For example, in Bangladesh TFR was more than 6.0 in the 1970s, but declined rapidly to 2.74 at present. But TFR is still very high in many countries mainly in Sub-Saharan Africa. Niger (7.75), Mali (7.29), Afghanistan (6.53), Ethiopia (6.12), Zambia (5.15), Kenya (4.56), Laos (4.41), Saudi Arabia (3.83), Pakistan (3.60), etc. • Why and how TFR declines? It depends on the behavior of couples. www.AssignmentPoint.com

  9. Why and how birth rate declined in Developing Countries? (2) • Major reasons why TFR declined rapidly Adoption of contraceptives was a reason, but more fundamentally, it was because of the transition from agrarian to industrialized modern society. 1) Rising expected return of investment in education, especially in higher education. Parents’ way of thinking changed from many children for labor force in agriculture to less children with higher education to get remunerable job for the bright future. 2) Delay of first marriage age (partly because of higher education) 3) Higher opportunity cost of women’s duty to take care of children 4) Lower infant mortality rate 5) Development of pension system and other social securities 6) Urbanization 7) Availability of contraceptives with low cost 8) Increased awareness www.AssignmentPoint.com

  10. Demographic Bonus (1) • For a large group of countries where fertility has declined sharply in the last two decades, the proportion of the working age population (15-64) will increase relative to younger and older dependent populations over the next few decades. With appropriate investments, policies and governance, countries can take advantage of this low dependency ratio, or 'demographic bonus', to launch economic, social, cultural and structural transformation. • Dependency ratio is the sum of child population (0-14) and aged population (65+) divided by working-age (15-64) population and, then, multiplied by 100. • Dependency ratio first increases when experiencing high population growth rate, but after that it starts to decrease (‘demographic bonus’) and then finally again it starts to increase (to aging society). www.AssignmentPoint.com

  11. Demographic Bonus (2) • If the ‘demographic bonus’ period is defined widely as the period until the dependency ratio takes a lowest figure (and starts to increase again due to increase of aged population), demographic bonus final year were 1990 in Japan, 2010 in Thailand, Singapore and Hong Kong, 2015 in Korea and China, 2020 in Malaysia and Vietnam, 2035 in India (and Bangladesh). www.AssignmentPoint.com

  12. To the Aging Society • The aging of Asian countries is expected to accelerate in years to come, as the generation with a large population size, who contributed to ‘demographic bonus’, will start turning 65 years of age. • The aged population accounted for more than 10% of the total population only in Japan and Hong Kong in 2000. But South Korea and Taiwan are projected to follow suit by 2010, while Singapore will likely do so by 2015. China is expected to join this group by 2020, to be followed by Thailand by 2025, Malaysia by 2030, Indonesia and Myanmar by 2035, and the Philippines by 2040. www.AssignmentPoint.com

  13. Japanese Economic Society UnderPopulation Onus • Economic impact: Decline in growth potential 1. Intensifying labor shortage 2. Declining savings rate • Social impact: Increasingly heavy pressure on social security system 1. Pension system demands reform 2. Increases forecast in medical expenses www.AssignmentPoint.com
