2. Key Issues
Why does development vary among countries?
Why does development vary by gender?
Why is energy important for development?
Why do countries face obstacles to development?

3. Learning Outcomes 9.1.1: Identify the HDI standard of living factor.
9.1.2: Identify the HDI health factor.
9.1.3: Identify the HDI access to knowledge factor.
Describe variations in level of development within countries and regions.

4. Why Does Development Vary among Countries?
United Nations (UN) developed a metric to measure the level of development of every country called the Human Development Index (HDI).
It is based on three factors:
Decent standard of living
Long and healthy life
Access to knowledge
Countries group into 4 classes
Level of development ranging from developed (Very High) to developing (Low).

5. FIGURE 9-2 HUMAN DEVELOPMENT INDEX (HDI) Developed countries are those with very high developed scores in The other classes are for developing countries.

6. FIGURE 9-3HDI BY REGIOIN Regions and other areas are shown in order of level of development. Developed regions are in red, and developing regions in green. Similar patterns will be used for a number of charts in this chapter.

7. Why Does Development Vary among Countries?
A Decent Standard of Living
UN measures standard of living based on two functions:
Gross national income (GNI)
Value of the output of goods and services produced in a country annually, including money that leaves and enters the country.
Gross domestic product (GDP) is similar except it doesn’t account for money entering and leaving the country.
Per capita GNI measures average (mean) wealth, not its distribution among citizens.
Purchasing power parity (PPP)
Cost of living adjustment made to the GNI.

8. FIGURE 9-4 INCOME GNI per capita PPP is highest in developed countries
FIGURE 9-4 INCOME GNI per capita PPP is highest in developed countries. The lowest figures are in sub-Saharan Africa and South Asia.

9. Why Does Development Vary among Countries?
A Long and Healthy Life
UN considers good health to be an important measure of development:
Main health indicator contribution to the HDI is life expectancy at birth.
Average life expectancies of a baby
Global average: 70 years
Developed country: 80 years
Developing country: 68 years
Better health and welfare in developed countries permit people to live longer.

10. FIGURE 9-10 LIFE EXPECT ANCY AT BIRTH The highest life expectancy is in Europe, and the lowest is in sub-Saharan Africa.

11. Why Does Development Vary among Countries?
Access to Knowledge
UN considers years of schooling to be the most critical measure of the ability of an individual to gain access to knowledge needed for development.
Quantity of Schooling
Average Years of schooling
Global: 7 years
Developing: 6 years
Developed: 11 years
Expected years of schooling
Developed: 16 years
Developing: 11 years
Quantity of Schooling
Years of schooling is the number of years that the average person age 25 during the country has spent in school.
Expected years of Schooling
This is a number of years that an average five-year-old child is expected to spend in school.
Children in developed countries are expected to attend college, but they aren’t expected to attend college in developing countries.

12. FIGURE 9-11 MEAN YEARS OF SCHOOLING The highest number of years of schooling is in North America, and the lowest numbers are in South Asia and sub-Saharan Africa.

13. FIGURE 9-12 EXPECTED YEARS OF SCHOOLING The highest numbers of expected years of schooling are in North America and Europe, and the lowest numbers are in sub-Saharan Africa and South Asia.

14. Why Does Development Vary among Countries?
Access to Knowledge cont’d:
Quality of Schooling
Pupil/teacher ratio
Global: 24 (primary school)
Developing: 26 (primary school)
Developed: 14 (primary school)
Literacy rate
Developed: >99%
Developing: 70-90%
Pupil/teacher ratio
If your pupils the teacher asked, the more likely that each student will receive instruction
Literacy Rate
Percentage of a country’s people who can read and write.

15. FIGURE 9-13 PUPIL/TEACHER RATIO, PRIMARY SCHOOL The lowest pupil/teacher ratio is in North America, and the highest is in sub-Saharan Africa.

16. FIGURE 9-14 LITERACY RATE Literacy is nearly 100 percent in developed countries. The lowest rates are in sub-Saharan Africa and South Asia.
