Transcript of Demographics
What social, political and economic factors determine population trends and demographics of a region.
What social and cultural factors determine population trends and demographics of a region
How do you determine level of development and standard of living
What human and physical features influence size and distribution of settlements
What processes cause changes in human settlements
How do push and pull factors and geography affect human migration.
Why Study Demographics
Demography is the scientific and statistical study of human populations.
Level of Development
Formerly almost exclusively an economic concept, the term development now signifies the expansion of human possibilities (in terms of life expectancy, education, infrastructure and standard of living).
General course or prevailing tendancy
What is a trend?
Marketers uses demography to help make decision about products and product placement. And other business decisions
Governments use demography to make political observations.
These observations can include:
Population of countries
What types of programs are needed
Predictions about future population and population breakdowns.
Science use demography study understand and study the way people live and interact with each other and Earth.
They accomplish this by studying trends
With demographics scientist can diagnose groups of people, what they need, and what and how much they will need in the future.
They can also use the statistics to give you really neat facts that you probably don't even need.
Average number of people living in an area
Given using "persons" per square mile.
We can not tell exactly how the worlds population will change in the future. So we use demographics to make predictions based on observable trends and past population information.
Density vs. Distribution
is the recognition that people are spread unevenly across Earth.
Why??? Why are people spread unevenly
People tend to gather around places
with fertile soil, fresh water, and
Populations change for 3 major reasons
The number of births for each year for every 1000 people
The number of people who die each year, per 1000 people
Migration: process of moving from one place to another.
Are reasons that a person leaves his or her current location and seeks an new one. Possible reasons could include.
Lack of opportunities
Emigrants are people who leave a country to live somewhere else.
Are reasons attract you from one place to stay in in another. Pull factors might include:
Immigrants are people who come to
a new country to live.
Based on just births and just deaths. The natural increase is genrally expressed as a %
Demographic Transition Model
Shows the birthrate and death rate through different stages of a country's development

Standard of Living and Quality of Life
A level of material comfort as measured by the wealth, goods, services, and luxuries available to an individual, group, or nation.
The basic facilities, services, and installations needed for the functioning of a community or society, such as transportation and communications systems, water and power lines, and public institutions including schools, post offices, and prisons.
Human Development Index
A tool developed by the United Nations to measure and rank countries' levels of social and economic development based on four criteria: Life expectancy at birth, mean years of schooling, expected years of schooling and gross national income per capita.
Per unit of population; per person
Indicators of Developement
Gross Domestic Product (GDP)
GDP Per Capita
Access to clean water
Daily Caloric Intake
Doctors per Capita
Acre of protected natural habitat
Automobile per Capita
Boats per Capita
2 Types of Countries
"Developing countries work their up way up the ladder of economic performance, living standards, sustainability and equality that differentiates them from more developed countries. The point at which developing countries become “developed” comes down to a judgment call based on a combination of development indicators."
