What is Demography?
The study of human populations, including their
size, growth, density, distribution, and rates of
birth, marriage, and deaths.
3
Population Density

• The number of people living per unit of an area
  (usually per square mile).

4
Birth Rate
The number of live births each year per 1000
people in a population.
Death Rate
The number of deaths each year per 1000 people in
a population.
Total Fertility Rate
Average number of children that women have.
5
Demographic Transition

• Definition the change from HIGH birth/death
  rates to LOW birth/death rates usually
  accompanies a cluster of other changes such as
  change from subsistence economy (families produce
  own food) to a cash economy (families purchase
  necessities with ), increased education rates,
  and urbanization

6
Migration

• The movement of people from one location to
  another in any setting, whether within a
  community, within a country, or between countries.

7
Emigrant
A person who exits a country to live elsewhere.
Immigrant
A person who moves into a country.
8
Migration Factors

• Push Factors Problems that push people out of
  one area into another. Ex. Hunger, landlessness,
  political instability, etc.
• Pull Factors Benefits that pull people into a
  new area. Ex. Jobs, housing, etc.

Age Structure Diagrams (Often Called Population
Pyramids)

• Classifies a population by gender and by 5 year
  increments. May classify a population by
  pre-reproductive, reproductive, and
  post-reproductive phases.
• Were going to draw the shape of what a country
  looks like with rapid, slow, zero, or negative
  growth

Gross Domestic Product (GDP)
The total market value of all the goods and
services produced within the borders of a nation
during a specific time period.
GDP Per Capita GDP divided by the total
population of a country. Average.
Population Below Poverty Line Percentage of
population making less than GDP per capita.
14
Purchasing Power Parity (PPP)

• Definition the amount that the local currency
  equivalent of U.S. 1 will purchase in a given
  country
• GDP Per Capita PPP the total market value of
  all goods and services produced within the
  borders of a nation in a year, divided by the
  total population of a country and adjusted for
  purchasing power parity

15
United Nations Human Development Index (HDI)

• The ranking of countries based on 3 indicators of
  well being
• Life expectancy at birth
• Educational attainment
• Income adjusted to purchasing power parity
• This is more complex than just looking at the GDP
  of a country

16

• Developing Country (LDC)
• Undeveloped economy
• No modern technology
• No industrial production
• Low standard of living
• Dependent on developed countries

• Developed Country (MDC)
• Well developed economy
• Modern technology
• Modern industry
• High standard of living

17
Characteristic MDC LDC
GDP Per Capita Income High Low
Percent in Middle Class High Low
Percent in Manufacturing High Low
Energy Use High Low
Percent Urban High Low
Percent Rural Low High
Birth Rate Low High
Death Rate Low Low (higher than MDC)
Population Growth Rate Low High
Percent Under Age 15 Low High
Percent Literate High Low
Leisure Time Available High Low
Life Expectancy High Low
