Population Population Presentation Transcript

  • Population
  • What is Population?
    • The collection of people living in a given geographic area, or space, usually measured by a census
    • Demography
      • The study of human populations
    • Various aspects of human behavior in populations are studied in Sociology, Economics, and Geography
    • The study of populations is almost always governed by the laws of probability

  • Worldwide Population Growth
    • Earth’s population hit 1 Billion in the early 1800’s
    • As the world industrialized, people grew more and better food
    • Also, people improved their sanitation methods
    • This combination enabled the population to boom

  • Trends in Population Growth Worldwide Population Increase and Growth Rate, Five-Year Periods Millions Percent increase per year Source: United Nations, World Population Prospects: The 2004 Revision (medium scenario), 2005.
  • Notes on Trends in Population Growth Worldwide
    • Over the period 1985-1995, the population growth rate declined (a reflection of declining fertility), yet millions of people were added to the world’s population (which peaked around 1985, when 87 million people were added each year).
    • From 2000 on, the growth rate will continue to decline.
    • Between 2015 and 2020, we will still be adding 72 million people each year. Why?
    • Because the generation of women now having their children is very large as the result of high fertility in their mothers’ and grandmothers’ generations.
  • Birth Rates
    • Birthrate- the number of live births per 1,000 population
    • In 2000, the highest birthrate in the world was more than 54/1000 in Niger
    • Lowest = 8/1000 in Latvia
    • World Average = 22/1000

  • Fertility Rate
    • Shows the average number of children a woman of childbearing years would have in her lifetime
    • A fertility rate of 2.1 is necessary just to replace current population
    • Today, the worldwide average fertility rate is about 2.59
  • Fertility Rates
    • What do you think the average number of babies each woman has in the world? US?
    • What do you think the highest average is? Where?

  • Questions to Consider
    • Why is the world’s population increasing but the growth rate is decreasing?
    • Why is the world’s population growing so quickly?
    • What problems/implications does this growth bring about?
  • Mortality Rate
    • Also called the death rate
    • Number of deaths per 1,000 people
    • Generally, a society is considered healthy if it has a low mortality rate
    • However, some healthy nations have higher mortality rates because they have large numbers of elderly people

  • Infant Mortality Rate
    • For this reason, geographers also look at infant mortality rates
    • Infant Mortality Rate
      • Shows the number of deaths among infants under age 1 per 1,000 live births
    • In the 1800’s, the worldwide I.M.R. was 300/1,000
  •  
  • Rate of Natural Increase
    • Birthrate – Death Rate
    • B-D = R

  • Human Population Growth Rate
  • Population Pyramid
    • Another way to analyze populations is to use a population pyramid
    • PP = a graphic device that shows sex & age distribution of a population
    • Allows geographers to examine how events in society, such as wars, famine, or epidemics, affect the population of a country or region

  • Population Density
    • The average number of people who live in a measurable area, such as a square mile
    • The number is reached by dividing the number of inhabitants in an area by the total amount of land they occupy
    • Geographers use this to understand how heavily populated an area is
    • Which countries do you think are the most densely populated?
    • GeoHive
    • List actual
  •  
  •  
  • Population Density
    • This number can be misleading for an entire nation
      • Why?
    • Example: U.S. P.D.  1990
      • Alaska = huge land area, small population
        • 1 person per square mile
      • New Jersey = small land area, large population
        • 1,098 people per square mile
    • Total U.S. Population Density = 70.3 people per square mile
  • Carrying Capacity
    • The number of individuals an environment can support without significant negative impacts
    • A region with fertile land may be able to support far more people than one with land of poor quality or with little land available for cultivation
    • Technology
      • Level of technology of a group living on the land may affect carrying capacity
  • Carrying Capacity

  • Land Area
    • Write what you think the five largest countries(land area) are.
    • GeoHive

  •  
  • Population Distribution
    • Of the billions of people in the world, most are not distributed equally across the earth
    • Some lands are not suitable for human habitation
      • Examples?
    • Almost 90% of the world’s population lives in the Northern Hemisphere
      • N.H.- ½ of the planets surface, which is north of the equator
  •  
  • Population Distribution
    • 1 in 4 people in the world live in East Asia, and 1 in 2 people live in either East Asia or South Asia
    • Factors:
      • Climate
      • Altitude
      • Access to water
      • All influence where people live
  • Urban-Rural Mix
    • Currently, more than ½ of the world’s population lives in rural areas
    • However, this number is changing rapidly
    • More and more people are migrating to cities
    • Particularly, cities with populations of more than one million people
