Population
Intro To Population
• What are we at right now?
– 6.5-7 Billion people in the world TODAY
• China – 1.4 Billion People
• India – 1.2 Billion People
• What does the future hold?
– Future Populations?:
• Increase into the future…why it will increase?
– Potential Problems…Why
• Not enough food for everyone
• Water shortages (for drinking & agriculture)
• Where are people going to live? Shelter, land, space
World Population Growth
• The world population IS Growing!
– Why is the population growing?
• Medical improvements (diseases, sicknesses)
• Technology Improvements (when we are sick…we can
make ourselves healthy)
• Greater Productivity = More food to feed the people
• Fight for power…encourage countries to increase labor
force
• We’ve made it harder to die…and easier to live.
– (We have separated ourselves from the FOREST/JUNGLE..with
Lions & Tigers & Bears….Oh My!)
Difference between 1 million & 1
billion
• You were 12 days old = 1 million seconds
– > 1 year old
• You will be 32 years old = 1 Billion seconds x 7
– 224 years old…= 7 billion seconds
Demography
• “Graphy” = Study of…something…
• Demography – The study of human populations
– Their INCOME
– The total #! (Country/city/world/house)
– Birth rates (how many people are born…in a certain
time/place/size)
– Death Rate (how many die…in a certain place, time
(year/day)
– Gender (how many males / females)
– Relationship Status (Single, Married, It’s Complicated,
Open)
Census
• What do we call the PROCESS of collecting this
Demographic INFORMATION?
• Census: Collecting information about a
population
– Why is a census important? Why have countries in
the past & present cared about this information?
– How/Why is it difficult to collect?
Census is Important Because…
• Allows us to accurately plan for the future
– Cause & Consequence of the future…gives us an idea
of what future will look like!
• To understand the future, we must understand our past &
present
– Ex. How many workers we will have
– Ex. How many students we will have
• Set the policy…and set future policies…and aid in
making important decisions. Ex. 1 Child Policy
• Also measures success rates (Yearly GDP, etc)
Migrations – Immigrants & Emigrants
• Immigrants: (I = In) A person who comes in
– An Immigrant is someone coming from another place.
(Shanxi goes to Shanghai. They are an immigrant in
Shanghai.
– A person from China, goes to Canada is an immigrant in
Canada)
• Emigrants: A person who comes out.
• These 2 factors affect Population!
– How does an Immigrant affect population/country?
What do they bring with them into a new place?
– How does an Emigrant affect population? What are they
bringing with them away from their place?
Affect of Immigrants
• Money (to spend in the economy) +
• Disease – Human/Plant/Animal (foreign disease
that local people don’t have protection against) –
• Technology/Education +
• Culture/Traditions/Beliefs + / - (Canada see’s this
as a positive..contributes to multicultural nation)
• Human Needs (Shelter, Food, Water) – must be
provided for ---
Affect of Emigrant – What they leave
behind
• “Brain Drain” – Take away their talents/skills --• Wealth taken away from country (ex. Lots of
gov’t officials send their wealth out of country)
• Human Needs are gone from that area (Food,
Shelter, Water)
