2. World Population
Essential Questions: How does the growing population of the world shape how we interact with others?
Learning Target: IWBAT describe how the world’s population is distributed.
Formative Assessment(s): What information can I tell about a country based on their crude birth rates? Crude death rate? Natural increase? Doubling time?

6. Classwork Birthrate: # of people born per year per thousand
Death rate: # of people who die per year per thousand
Natural increase: the growth rate (births minus deaths)
Migration: movement of people from place to place

Answer these questions as we watch:
The video lists the population of Earth as approximately 1 billion in the year 1800, which means it took the earth almost 12,000 years (starting with the first civilizations 10,000 years ago) of human habitation to reach 1 billion. Describe how many years from 1800 it took to reach each of the following milestones:
Why do think there has been such a quick population growth in the last 230 years?
By how much did the life expectancy increase between 1960 and 2010?
The video discusses the rise of urbanization (living in cities) among the human population. How does it define a megacity? How many megacities are there currently?
One of the more interesting parts of the video describes space – according to the video, if all the people on earth stood shoulder to shoulder, what U.S. city would we all fit into?
So then what, according to the video, are some problems facing the world due to having 7 billion people?

The video lists the population of Earth as approximately 1 billion in the year 1800, which means it took the earth almost 12,000 years (starting with the first civilizations 10,000 years ago) of human habitation to reach 1 billion. Describe how many years from 1800 it took to reach each of the following milestones:
2 Billion: 130 years
3 Billion: 160 years (+ 30 years)
4 Billion: 174 years (+ 14 years)
5 Billion: 187 years (+ 13 years)
6 Billion: 199 years (+ 12 years)
7 Billion: 211 years (+ 12 years)
Why do think there has been such a quick population growth in the last 230 years?
People are living longer due to better medicine and technology, more babies are surviving to adulthood, industrial revolution means more goods more readily available, more food, less disease, etc
By how much did the life expectancy increase between 1960 and 2010?
It increased from 53 to 69, 16 years!
The video discusses the rise of urbanization (living in cities) among the human population. How does it define a megacity? How many megacities are there currently?
A megacity is a city with a population over 10 million. Today there are 22 megacities (21 according to the video).
One of the more interesting parts of the video describes space – according to the video, if all the people on earth stood shoulder to shoulder, what U.S. city would we all fit into?
Los Angeles
So then what, according to the video, are some problems facing the world due to having 7 billion people?
Problems of energy conservation, clean water, sanitation, language.

Answer these questions as we watch:
Describe all of the physical and cultural characteristics of the world’s most typical person.
By 2030, from what country will the world’s most typical person come from?
The video also talks about life expectancy – specifically how a woman in Japan will live on average 86 years, while the life expectancy of an Afghan woman is 45 (41 years difference)! Why do you think there is such a difference in the life expectancy of women based on geographic differences?

Describe all of the physical and cultural characteristics of the world’s most typical person.
They are right handed, make less than $12,000 a year, has a cell phone, does not have a bank account, is a 28 year old Chinese man.
By 2030, from what country will the world’s most typical person come from?
India
The video also talks about life expectancy – specifically how a woman in Japan will live on average 86 years, while the life expectancy of an Afghan woman is 45 (41 years difference)! Why do you think there is such a difference in the life expectancy of women based on geographic differences?
I would expect a difference in lifestyles between these two regions. Japanese women are more likely to work in the service industry and buy everything they need at stores. Afghan women most likely work at home, have more children (putting them at risk in childbirth), and make most of the things they use.
