1. POPULATION GEOGRAPHY Introduction

2. What is Population Geography?  A division of human geography concerned with spatial variations in distribution, composition, growth, and movements of population.

3. 7 BILLION PEOPLE on the planet. :-O We currently have… http://www.worldometers.info/world-population/

4. Ecumene  Portion of the world’s land surface that is permanently settled by human beings.  75% of people live on only 5% of the earth’s surface.  About 50% of people on the earth live in cities.

5. Demography  The study of the patterns and rates of population change, including birth and death rates, migration trends, and evolving populations distributions.  Demographics= statistical characteristics of a population  Gender, age, race, disabilities, mobility, home ownership, employment status, location, etc.

9. Linear Versus Exponential Growth How is our population growing?

10. Doubling Time  Time period required for a population experiencing exponential growth to double in size completely.  At a 3% growth rate, the time it will take for a population to double is less than 25 years.  Growth rates currently exceed 3% in parts of sub- Saharan and tropical Africa, the Middle East, and Central America.

11. Where is the population growing?

12. Carrying capacity  Maximum number of people a region can reasonably sustain.

13. Overpopulation  Occurs when a region exceeds its carrying capacity. This is difficult to measure because of changing technology and environmental issues that continually alter the carrying capacity.

14. Overcrowded  Simply too many people but the carrying capacity has not been reached.

15. Underpopulation  Measure that is difficult to pinpoint; occurs when a population size is below its carrying capacity and cannot sustain the economic development it has reached.  Trouble filling jobs and fulfilling responsibilities to society.

16. Zero Population Growth  Proposal to end population growth through a variety of official and nongovernmental family planning programs.  Many activists in the more-developed countries believe overpopulation is the root cause of the world’s social and environmental problems.
