Demography Day!
Mon., Sept. 14, 2015 Chapter 1 Pages 11-21

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.

9
Zero Population Growth (ZPG)
birth rate immigration rate death rate
emigrant rate
10
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
