  1. Population Unit 2 Copeland APHG

  2. Population Geography • Elements of Population Geography (focuses on spatial aspects of demography) • Demography (study of population) • Population Distribution • Population Density • Arithmetic Population Density • Physiological Density • Rate of Natural Increase (the excess of births of deaths – omitting migration) • Growth Rate (Natural increase + Net Migration)

  3. Why Study Population? • As the proportion of older people in a country increases, the proportion of younger people decreases. • Why is this a problem? fewer young workers paying for more pensions and medical expenses for older population, therefore less pension and medical benefits to go around.

  4. Where are all the children? • Travel to Europe, Japan or Canada and you will notice there are very few kids to be found. • What causes this phenomena? • Women in wealthier countries are having fewer children. Why? • In many of these locations, the Total Fertility Rate (TFR) has dropped below 2.1. In order to keep a population stable over time, the women in a country must have a TFR of 2.1 or higher. • The Total Fertility Rate reports the average number of children born to a woman of child-bearing age. • The TFR highs and lows…Italy=0.8 Kenya=8.1 *highest ever

  5. Population Terms • Demography- the study of population characteristics • Overpopulation- when the available resources cannot support the number of people • Density- How many? The total number of people

  6. Demography • The study of human populations, particularly the size, distribution, and characteristics of members of population groups.

  7. Distribution and Density

  8. Population Growth • 0 AD 250 Million People • 1803 AD 1 Billion People • 1903 AD 1.6 Billion People • 1950 AD 3.0 Billion People • 1987 AD 5.0 Billion People • 1998 AD 6.0 Billion People • 2011 AD 7.0 Billion People

  9. The World and the Top 10 • World7,254, 596, 819TODAY 8/18/14 8:07AM • China1.3 billion • India1.2 billion • United States321 million • Indonesia251 million • Brazil201 million • Pakistan183 million • Nigeria 176 million • Bangladesh 157 million • Russia142 million • Japan127 million • Next…Mexico 123 million

  10. Population Distribution – Descriptions of locations on the Earth’s surface where individuals or groups (depending on the scale) live. Dot Map of World Population – On this map, one dot represents 100,000 people

  11. Cartogram Countries are displayed by size of population rather than land area. Countries named have at least 50 million people.

  12. World Population Clusters • Two-thirds of the world’s population are concentrated in four regions: 1. East Asia (East China, Japan, S. Korea, Taiwan) - ¼ of world population here 2. South Asia (India, Pakistan, Bangladesh) - bound by the Himalayas and a desert in Pakistan 3. Europe - population is concentrated in cities 4. North America - megalopolis

  13. Ecumene=inhabited earth • The portion of the Earth’s surface occupied by permanent human settlement • Increased over time • ¾ of world population lives on only 5% of the Earth’s surface

  14. Densely populated regions Low lands Fertile soil Temperate climate Sparsely Populated Regions dry lands wet lands high lands cold lands Population Distribution
