Cover Slide Continued

• Fertility, Mortality, and Migration are all used
  to consider he demographics of a population.
• The worlds population is increasing, whereas the
  rate at which it is growing is decreasing.
• Urbanization happens differently and at different
  speeds everywhere.
• The four major theories of city growth
  concentric zone theory, sector theory, multiple
  nuclei theory, and peripheral theory

Population and Demography

• Population a group of people living in a
  particular place at a specified time or a group
  of people with specified characteristics
• Demography the scientific study of population

4

• Fertility a measure of the number of children
  born to a woman or a population of women
• Crude birthrate the annual number of live births
  per one thousand members of a population
• Fertility rate the annual number of live births
  per one thousand women aged fifteen to forty-four

5
Producing Children Fertility Cont.

• Fecundity the maximum rate at which women can
  physically produce children
• Total fertility rate average number of children
  born to a women during her lifetime

6

• Life expectancy the average number of years that
  persons in a given population born at a
  particular time can expect to live
• Life Span the most advanced age to which humans
  can survive

7
Death

• Mortalitydeaths within a population
• Crude death rate the annual number of deaths per
  one thousand members of the population
• Infant mortality rate the annual number of
  deaths among infants under one year of age per
  one thousand live births

8
Migration!

• Migration the movement of people from one
  geographic area to another
• Gross migration rate the number of persons per
  year per one thousand members of the population
  who enter or leave a geographic area

• Net migration rate the annual increase or
  decrease per one thousand members of a population
  resulting from migration into and out of the
  population

Thomas Malthus
Thomas Malthus was an English minister who wrote
about the struggles trying to make food supply
keep up with the population growth. He was one of
the first to notice that the changes in
population can drastically affect many diverse
things. He described an intricate relationship
between population growth and economic
development.
