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)
