1. Introduction to Population p. 317 Class 3

2. Intro to Population
Present World Population: 6.5 – 7.2 Billion People in the world
China: ~ 1.3 – 1.4 Billion people
India: ~ 1 – 1.5 Billion People
Future of the World Population:
Going to INCREASE!
Why? People are “making babies;)”
Birth rate is more than the death rate
Possible Issues / Problems?
Over population
Live on a different planet..why?
Age?
Access to Resources?

3. World Population Growth
Why has population GROWN so much in the past years??
Reasons for large explosion of Human Population:
Industrial Revolution (Growth of Technology = decline of death rate)
Higher chance to survive BECAUSE living conditions/quality has improved/become better
No restrictions on # of kids (for most places/long time)
Policies about family planning…countries encouraged people to make babies!
Technology to provide FOOD/Products (need more people..and can provide for more people)
Medicine (cure illness/sickness/disease)
Basically…we have made it harder to die than in the past~!

4. Demography “graphy” – The study of……something!
Demography: The study of….. Human Population
The study of Mathematics / Social Studies / Physics
What can we study ABOUT the Human Population?
In the Human Population, we can focus/study:
Control of Population
Total # of people (in a country/city/school/world)
Birth rate / Death rate (where are people dying/born, how old, etc)
Gender (How many males:females)
Nationalities/Ethnicities of people
Patterns of population growth (timeline)
Age of people!!
Income
Education

5. Why Study Demographics of a population?
Who cares about this stuff? Why?!
Why is this useful?
Governments/Countries/World Organizations care because…helps to predict (and PLAN) for the future!!
Who: Parents? Governments…World Organizations (United Nations..?) Political Parties
Why?: Political Views of people? Male/Female could influence the culture

6. The process of collecting demographic data is called….Census!
Census: The process of collecting human population information!
Why…clearly see what we HAVE…and What we WILL have…
Problems with collecting a Census?...
Hard to count..why?: Migration! People move! Especially in areas without a clear address
North Pole…Santa Claus lives..
Remote…in the countryside
No man’s land…has no address
Afghanistan/Africa/Syria/Natives who live in the jungle
Developed/Developing?...Developing countries

7. Types of Migration Migration: The movement of an animal
Side Note: Study Strategy…Make the information make sense to you…
Two Types:
Immigration (I = IN): People go IN TO a country
**How does Immigrants influence a country? What do they BRING WITH THEM??
Emigration (E = EXIT): People LEAVE a country!
** How do Emigrants influence a country? What do they leave with?? Leave Behind?

8. Influence of Immigrants/Emigrants to a Country
Bring habits/culture/traditions/values/beliefs (+/-)
Man power/Labor force (+)
Products/Likes
Competition (for business/jobs)
Most immigrants are young (energy, want to have babies, educated, talented, money…)
Human Needs (Food, Water, Place to live…) (-)

9. Emmigrant:
- “Brain Drain” – Take away their talent/brain from their hometown
Technology/education/knowledge
Human Needs (food, water, shelter) (+)
