1. What were the populations of the global core and periphery in 1960?

            Global core = 1 Billion

Periphery = 2 Billion


2. To what “gap” does Rosling refer?

Rosling explains the gap in living standards and social-economic development that exists between populations in the Global Core and the Global Periphery.


3. Describe the changes in the world population between 1960 and 2010.

            a. Population increased by 4 billion.

            b. Almost all of the population growth occurred in the Global Periphery.

c. The core experienced economic growth, so did some countries in the periphery. Those countries are called Emerging Economies. They represent 4 billion people who have living standards that are in the gap between the richest 1 and poorest 2 billion.


4. What changes does he predict for the global population between 2010 and 2050?

            a. China will join the Global Core making the Core’s population 2 billion.

b. Emerging economies will experience economic growth and grow at a slower rate because of lower total fertility rates.

c. The two billion poorest might double in size if their standards of living are not improved.



5. What are the measures on Rosling’s graph? Total Fertility Rate and Child Survivability


6. What does each of these indicate about a country’s population? Child Survivability is an indicator of a country’s living standards: high living standards = high survivability. Total Fertility Rate is also an indicator of a country’s living standards: high living standards = low total fertility rate.


7. What happens to each of these indicators after Rosling begins the graph?

Total Fertility Rate decreases and Child Survivability increases.


8. Why? An improvement in a country’s living standards is usually accompanied by, and a result of, increased education for women and control of their reproduction. Increased living standards also are accompanied by an improvement in nutrition and health care, which improves survivability.


9. Why do the poorest 2 billion people continue to have high total fertility rates?

Poor living standards: Lack education for women and girls, lack of access to means to control reproduction, low child survivability.
