Title: Introduction to Population Geography

September 22, 2014
  • Introduction to Population Geography

What is population geography?
  • Population Geography focuses on the number,
    composition, and distribution of human beings on
    the earths surface
  • Population geographers are interested in
    population changes-both growth and
    movement-especially as they relate to the earths
    environment and natural resources

Why study population geography?
  • The study of population geography is critically
    important for three reasons
  • More people are alive at this time-more than 7
    billion-than at any point in Earths history
  • The worlds population increased at a faster rate
    during the second half of the twentieth century
    than ever before in history
  • Virtually all global population growth is
    concentrated in less developed countries

  • Geographers argue that the worlds so-called
    overpopulation problem is not simply a matter of
    the total number of people on Earth, but the
    relationship between the number of people and the
    availability of resources.
  • Problems result when an areas population exceeds
    the capacity of the environment to support them
    at an acceptable standard of living.

Population Statistics
  • All population theories rest on an understanding
    of these basic concepts
  • Crude Birth Rate the number of live births in a
    given year for every thousand people in a
  • Crude Death Rate (also called the mortality
    rate) the number of deaths in a given year for
    every thousand people in a population
  • Life expectancy the number of years that a child
    can expect to live, given current mortality rates

Population Statistics
  • Total fertility rate the average number of
    children a woman will have throughout her
    childbearing years
  • Infant mortality rate the number of deaths among
    infants under one year of age for each 1,000 live
  • Natural increase the difference between the
    number of births and the number of deaths during
    a specific period

The Demographic Transition Model
  • All countries have experienced changes in natural
    increase, fertility, and mortality rates, but
    their pattern vary considerably
  • According to the Demographic Transition Theory,
    these changes occur in stages according to levels
    of technological advancements
  • Demography is the study of population

The Demographic Transition Model
  • The "Demographic Transition" is a model that
    describes population change over time. It  is
    based on an interpretation begun in 1929 by the
    American demographer Warren Thompson, of the
    observed changes, or transitions, in birth and
    death rates in industrialized societies over the
    past two hundred years or so.

What does it look like?
Stage 1 (low growth)
  • This stage is preindustrial, and characterized by
    high birthrates and high death rates and low
    population growth
  • Children are seen as economic assets as they
    provide a steady supply of labor
  • Death rates are high because of low standards of
    living and little medical technology
  • The natural increase rate is close to 0
  • The Earths population was in this stage until
    the mid-1700s

Stage 2 (high growth)
  • This stage is industrial, and characterized by
    high birth rates, low death rates, and high
    population growth
  • Children are still seen as economic assets
  • Death rates are low due to access to medical
    technology, and a steady food supply
  • Many Less Developed Countries are still in this
    stage and see high population growth
  • The Earths population was in this stage until
    the I800s

Stage 3 (moderate growth)
  • This stage is a mature industrial economy when
    the birth rate drops, curbing population once
    again. This stage is characterized by low birth
    rates, low death rates, and low population
  • The birth rate is low because more women are
    educated and work outside the home
  • Children are seen as economic liabilities
  • Women delay marriage and having children
  • Death rates remain low

Stage 4 (low growth)
  • This stage is post-industrial, and characterized
    by extremely low or even negative birthrates, low
    death rates, and low or negative population
  • Birthrates are low or negative as women seek
    higher education
  • Women delay marriage and having children even
    longer than in Stage 3
  • Medical technology is at the most advanced stage,
    increasing life expectancy
  • Countries might experience negative population
