World Population Growth • Describe in detail the growth of the world population. • Describe the unequal growth between ELDC’s and EMDC’s • Think about future world population trends.
What does this mean? • Current population 6 483 149 925 • Every month 10 834 440 births and 4 677 520 deaths. • Every Day 356 201 births and 153 781 deaths. • Every Hour 14 042 births and 6 400 deaths. • Every Minute 247 births and 107 deaths. • Every second 4.1 births and 1.8 deaths…………
That is…….. • 2 extra people in the world every second!!!!!!!
World population distribution shown as % of total population What are the implications of these trends?
That means…. • Greatest rate of growth is in the ELDC’s with an extra 85 million people every year. • Europe’s population is expected to fall. Only an extra 1.5 million per year and shrinking. • Birth rate in Europe is 1.4 • Birth rate in Africa is 6. • Current projections suggest population will continue to rise reaching 27 billion by 2150. • ………What are the implications of these trends?
What would happen if it was accurate??? • Ageing population in EMDC’s – economic disaster. • Population Bomb in ELDCs’ – Leading to war. • Global food crisis. • Global land crisis – SPACESHIP EARTH! • Environmental Impact. • The Malthus Theory “Eventually population will be checked by misery and vice in the form of famine, disease and war”
Think about it… • At current rates of growth the projected population in 2150 will be 27 billion. • What might slow down this growth?
What might slow down this growth??? • Birth control in ELDC’s • AIDS epidemic • Education • Family Planning. • Anti-Natalist Policies – One Child – China. • Increasing living standards. • Natural controls – Famine, Tsunami, Drought…………..Supervolcano?!!!!!
Reducing Fertility Rates - success? • Fertility rates in most regions of the world have fallen with the exception of Africa. • USA 2.06 • Italy 1.18 • China 1.82 • India 3.11 • How has this been achieved?
How has this been achieved? • Improved contraception – forced sterilization in India. • Increased knowledge and acceptance of contraceptives. • Reduced Child Mortality!!!! • High Rates of Urbanization. • Increased education of women and their earning power.
We will continue to look at these issues in more detail over the next few weeks. • Key Words • Crude Birth Rate (CBR) Number of live births per 1000 people in one year. • Crude Death Rate (CDR) Number of deaths per 1000 people in one year. • Infant Mortality Rate The number of deaths of infants under one year of age per 1000 people in one year. • Life expectancy The average number of years from birth that a person can expect to live.
