Measuring Inequality & The Formal Economy [AP Human Geography Unit 7 Topic 3] (7.3)

Measuring Inequality and the Formal Economy

The video explains how economists and geographers measure economic activity, development, and inequality. Its central advice is to understand what each indicator measures and how to interpret it, rather than focusing mainly on memorizing calculations.

Formal and Informal Economies

• Formal economy: Economic activity monitored or regulated and taxed by the government, such as a conventional hourly or salaried job.
• Informal economy: Economic activity that is not monitored or taxed by the government. Examples include under-the-table businesses and unreported goods and services in squatter settlements.

Informal economies are difficult to measure and are often larger in less developed countries than in developed countries.

Economic Indicators

• GDP (Gross Domestic Product): The total value of goods and services produced within a country’s borders in one year. It indicates the scale of production and consumption. Rising GDP can suggest economic growth, while falling GDP can indicate an economic pullback.
• GNP (Gross National Product): The value of goods and services produced by a country’s citizens, both at home and abroad.
  • Example: Cars produced by the Japanese company Toyota in the United States count toward U.S. GDP because they are produced there, but toward Japan’s GNP because Toyota is Japanese.
• GNI (Gross National Income): A measure related to GDP that accounts for income flows across borders: GDP minus income sent abroad, plus net income received from production abroad.
  • Example: Profits from Tesla cars produced in China and sent back to the United States count toward U.S. GNI.
• GNI per capita: National income divided by population. It is used as an indicator of a country’s standard of living; a higher value generally suggests a higher standard of living.

Other Measures of Social and Economic Development

Development can also be assessed through measures such as:

• Income distribution, which shows how wealth is spread across society
• Infant mortality
• Access to health care and education
• Literacy rates

Gender Inequality and Human Development

• Gender Inequality Index (GII): Measures gender inequality using reproductive health, empowerment, and labor-market participation. A lower score indicates less inequality, while a higher score indicates more inequality.
• Human Development Index (HDI): Combines life expectancy, expected years of schooling, and GNI per capita. Scores range from 0 to 1:
  • Scores closer to 1 are associated with longer lives, more schooling, and a higher standard of living.
  • Scores closer to 0 are associated with lower living standards and less access to health care and education.

Study Guidance

Focus on what each indicator measures and what its values suggest about a country and its citizens. On tests, these measures may appear in charts or tables that are already calculated, so interpreting the information is especially important.
