Geography Unit 2: Population and Migration

Cards in this deck (88)

  1. 1World PopulationThe total number of humans currently living.
  2. 2Population Clusters2/3rds of the world's population.
  3. 3How many regions are the world's inhabitants clustered in?Four
  4. 4The four Population Cluster Countries/RegionsEast Asia
    South Asia
    Southeast
    Asia
    Wester Europe
  5. 5Arable LandSuitable Land for Planting Crops
  6. 6Arithmetic DensityThe total number of people divided by total land area.
  7. 7Why is Arithmetic Density useful?Because Geographers rely on Arithmetic Density to compare the conditions of different countries. Doing this results in the two pieces of information needed to calculate the measure and total population/land area are easy to obtain.
  8. 8What is the Arithmetic Density of the US?32 people per square kilometer
  9. 9Sparsely Populated RegionsPeople scattered in different areas.
  10. 10How do you calculate Arithmetic Density?Divide the population by the land area.
  11. 11Do people live in large numbers in certain physical environments?No.
  12. 12Physiological DensityPeople supported by a unit area of arable land.
  13. 13Why is Physiological Density useful?Physiological Density offers insights into relationships between the size of a population and the availability of resources in that particular region.
  14. 14What is the Physiological Density of the US?175 people per square kilometer of arable land.
  15. 15What happens when you compare Physiologically and Arithmetic Densities?It helps you understand the capacity of the land to give enough food for the need of the people.
  16. 16What happens with Physiological Density when the Density is higher?If the Density if high, the greater the pressure that people may place on the land to produce enough food.
  17. 17(Example of P.D) What does the large difference between the physiological density and arithmetic density in Egypt mean?It means that most of the country's land is unsuitable for intensive agriculture.
  18. 18DensityThe frequency with which something occurs in space.
  19. 19Agricultural DensityThe ratio of the number of farmers to the number of arable lands.
  20. 20Why is Agricultural Density useful?Measuring agricultural Density helps to account for economic differences.
  21. 21Why do Developed countries have lower agriculture densities?Developed countries have lower agriculture densities because technology and finance allow a few people to farm extensive land areas and feed many people.
  22. 22What do Geographers do to understand the relationship between population and resources in a country?They examine the Physiological and Agricultural Densities together.
  23. 23Natural Increase RateThe Percentage by which a population grows in a year
  24. 24Why is Natural Increase Rate Useful?Because Natural Increase Ratehelps to keep track of the trends of the population.
  25. 25Crude Birth Rate (C.B.R)The number of live births in a year for every 1,000 people alive in the society.
  26. 26Why is C.B.R Important?C.B.R is important
    Because it helps to compare between different groups, countries, regions etc.
  27. 27What does a C.B.R of 20 Mean?A CBR of 20 means that for every 1,000 people in a country, 20 babies are born over a 1-year period.
  28. 28Crude Death Rate (C.D.R)The total number of deaths in a year for every 1,000 people alive in the society.
  29. 29How is knowing C.D.R Helpful?Because it is C.D.R is a helpful indicator on figuring out the health statuses of different places/countries/
    regions
  30. 30Life ExpectancyAt Birth, it measures the average
  31. 31Where is Life Expectancy more favorable?Life Expectancy is more favorable in Wealthy countries
  32. 32How is Life Expectancy helpful?Because it helps to measure the health status across an age group.
  33. 33Total Fertility Rate (T.F.R)The average number of children a woman will have throughout her childbearing years.
  34. 34How is T.F.R Useful?Fertility Rate is useful because it attempts to predict the future behavior of individual women in a world of rapid cultural change.
  35. 35What are the ages for T.F.R?Roughly 15-49
  36. 36Infant Mortality Rate (I.M.R)The annual number of deaths of infants under 1 year of age out of every 1,000 births.
  37. 37How is knowing I.M.R useful?Because it reflects a country’s health-care system
  38. 38Where are Lower I.M.Rs found?Lower IMRs are found in countries with well-trained doctors and nurses, modern hospitals, and large supplies of medicines.
  39. 39Population PyramidA bar graph that displays the percentage of a place’s population for each age and gender.
  40. 40Three types of Population PyramidsThree types of Population Pyramids
  41. 41What is the Population Pyramid determined by?Crude Birth Rate (C.B.R)
  42. 42Why is a population pyramid useful?Because The Population Pyramid is a tool made to help understand the makeup of a given population
  43. 43Dependancy RatioThe Number of people who are too young or too to work compared to the number of people in their productive years.
  44. 44Why is Dependancy Ratio useful?Because The Dependency Ratio helps us tell the financial burden that people have compared to others in different countries.
  45. 45Who is usually known to be classified as independent?People who are 0-14 years of age and 65-plus are normally classified as dependents.
