- 2. Population Population Terms Population Growth Population Distribution Population Density Population Characteristics Population Pyramids Demographic Transition Solutions to Population Growth
- 3. 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
- 4. 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
- 5. Population Distribution Population Concentrations – East Asia – South Asia – South East Asia – Europe – North America Sparsely Populated Regions – dry lands – wet lands – high lands – cold lands
- 6. Population Population Terms Population Growth Population Distribution Population Density Population Characteristics Population Pyramids Demographic Transition Solutions to Population Growth
- 7. Arithmetic Density: The total number of people divided by the total land area.
- 8. Arithmetic Density: The total number of people divided by the total land area.
- 9. Arithmetic Density: The total number of people divided by the total land area.
- 10. Physiological Density: The number of people per unit of area of arable land, which is land suitable for agriculture.
- 11. Physiological Density: The number of people per unit of area of arable land, which is land suitable for agriculture.
- 12. Agricultural Density: The number of farmers to the total amount of land suitable for agriculture.
- 13. Density Arithmetic Density: The total number of people divided by the total land area. Physiological Density: The number of people per unit of area of arable land, which is land suitable for agriculture. Agricultural Density: The number of farmers to the total amount of land suitable for agriculture.

- 15. Crude Birth Rate : The total number of live births in a year for every 1,000 people alive in the society.
- 16. Crude Death Rate : The total number of deaths in a year for every 1,000 people alive in the society.
- 17. Natural Increase: The percentage growth of a population in a year, computed as the crude birth rate minus the crude death rate.
- 18. Population Characteristics Crude Birth Rate : The total number of live births in a year for every 1,000 people alive in the society. Crude Death Rate : The total number of deaths in a year for every 1,000 people alive in the society. Natural Increase: The percentage growth of a population in a year, computed as the crude birth rate minus the crude death rate.
- 19. Population Characteristics Fertility Rate: The average number of children a woman will have throughout her childbearing years. Doubling Time: The number of years needed to double a population, assuming a constant rate of natural increase.
- 20. Infant Mortality Rate: - the number of deaths of children under the age of 1, per thousand of the general population.
- 21. Population Characteristics Life Expectancy : The average number of years an individual can be expected to live, given current social, economic, and medical conditions. Population under the age of 15 - usually shown as a percentage of the total population of a country - dependency ages Population over the age of 65 - usually shown as a percentage of the population. dependency age
- 22. Life Expectancy : The average number of years an individual can be expected to live, given current social, economic, and medical conditions.
- 23. Population under the age of 15 - usually shown as a percentage of the total population of a country - dependency age is 0-15
- 24. Population Population Terms Population Growth Population Distribution Population Density Population Characteristics Population Pyramids Demographic Transition Solutions to Population Growth
- 25. Population Pyramids Inverted bar graphs that show a wide population base (younger population) with a narrow top (older population). Population Pyramids show: – Age Distributions – Dependency Ratios of under 15 and over 65 – Sex Ratio - Male vs. Female
- 26. Developing Relatively Developed Developed (poor) (rich)
- 27. Population Population Terms Population Growth Population Distribution Population Density Population Characteristics Population Pyramids Demographic Transition Solutions to Population Growth
- 28. POPULATION & DEMOGRAPHIC PYRAMIDS TRANSITION
- 29. Demographic Transition - Stage 1 Demographic Transition - the change in population characteristics of a country to reflect medical technology or economic and social development. Crude Birth Rate: High 40-50 / 1,000 Crude Death Rate: High 40-50 / 1,000 Natural Increase Rate: None 0 / 1,000 Today, no country in the world is in Stage 1.
- 30. Demographic Transition
- 31. Demographic Transition - Stage 2 As medical technology is introduced, a population lives longer as the death rate is lower from the rates of stage one. Crude Birth Rate: High 40+ / 1,000 Crude Death Rate: Lower 15 / 1,000 Natural Increase Rate: Very High 25+/1,000
- 32. Demographic Transition - Stage 3 As the wealth and education of a country increases, social norms, and use of contraception dictate the birth of fewer children per woman. Crude Birth Rate: Lower 20 / 1,000 Crude Death Rate: Low 10 / 1,000 Natural Increase Rate: Low 10 / 1000
- 33. Demographic Transition - Stage 4 As the final stage in the transition of population characteristics, the fourth stage sees the population increase rate again at 0. This stage reflects a highly industrialized, educated society. Crude Birth Rate: Low 10 / 1,000 Crude Death Rate: Low 10 / 1,000 Natural Increase Rate: None 0 / 1,000
- 34. Population Population Terms Population Growth Population Distribution Population Density Population Characteristics Population Pyramids Demographic Transition Solutions to Population Growth
- 35. Solutions to Population Growth Education Birth Control Socialization Abortion Sterilization Government mandate Population redistribution
- 36. Solutions to Population Growth Migration to resource rich areas Empowerment of Women $ for contraception & education Improving farming techniques in poor areas Sterilization Educating men w/ responsibility for birth control Changing cultural norms to value girls
- 37. Solutions to Population Growth Addressing traditional religious values that may encourage gender preference and large families Starvation Medical technology - costs of maintaining vulnerable populations (old & young) Disease Biological Warfare
- 38. Solutions to Population Growth Redistribution of wealth - improve standard of living for poor so that children aren’t as necessary Addressing government policies to deal with their growing populations Environmental pollution causing higher death rates
- 39. Population Population Terms Population Growth Population Distribution Population Density Population Characteristics Population Pyramids Demographic Transition Solutions to Population Growth
