Which indicator measures the average income per person in a country?
Poverty headcount ratio
GDP per capita
Human Development Index
Gini coefficient
GDP per capita divides a country's total GDP by its population, representing the average income level. It directly reflects the income available to each person on average.
The Human Development Index (HDI) combines which three dimensions?
Health, education, and standard of living
Population growth, health, and unemployment
Life expectancy, inflation, and political stability
Income inequality, education, and poverty
The HDI aggregates three core dimensions: a health measure (life expectancy), an education measure, and a standard of living measure (GNI per capita). These capture human well-being beyond income alone.
What does a Gini coefficient of 0 indicate?
Perfect equality
Balanced poverty and wealth
Majority share by the top 10%
Perfect inequality
A Gini coefficient of 0 means that income or wealth is perfectly equally distributed among the population. No individual has more or less than another.
Which region typically has the highest average HDI?
Western Europe
South Asia
Latin America
Sub-Saharan Africa
Western Europe consistently records very high HDI values due to strong health, education, and income indicators. Other regions lag due to lower averages in one or more dimensions.
If a country's Gini coefficient rises from 0.35 to 0.45, what does this indicate?
Income inequality has decreased
Income inequality has increased
Education levels have improved
GDP has grown faster than population
An increase in the Gini coefficient signifies a rise in income or wealth inequality within that country. Higher values mean the distribution is more unequal.
Country A and Country B both have a GDP per capita of $10,000, but Country A has a life expectancy of 75 years and Country B has 65 years. Which indicator best reflects this health difference?
Gini coefficient
GDP per capita
HDI
Poverty rate
The Human Development Index incorporates life expectancy as its health dimension, capturing differences in longevity. GDP per capita alone does not reflect health outcomes.
A country reduces its poverty headcount ratio at $1.90/day from 20% to 10%. What does this show?
Higher median incomes only
An increase in income inequality
A growth in GDP without social change
A reduction in extreme poverty
The headcount ratio at the $1.90/day threshold measures extreme poverty. A drop from 20% to 10% indicates that fewer people live below that global poverty line.
If the Lorenz curve moves closer to the line of equality over time, what happens to the Gini coefficient?
It cannot be determined
It decreases
It increases
It remains unchanged
The Gini coefficient equals twice the area between the line of equality and the Lorenz curve. As the curve moves closer, that area shrinks and the Gini coefficient falls.
Which scenario suggests economic growth has not improved living standards?
High GDP growth and rising median household income
High GDP growth accompanied by reduced Gini
High GDP growth but stagnant median household income
Low GDP growth and rising median household income
If GDP growth does not translate into higher median incomes, most households may not experience improved living standards despite aggregate growth.
Which region has historically exhibited the highest poverty headcount ratio at $1.90/day?
Sub-Saharan Africa
Middle East and North Africa
South Asia
Latin America
Sub-Saharan Africa has persistently had the highest share of its population living below the $1.90/day extreme poverty line compared to other regions.
A country's HDI increased mainly due to an improved education index while income and health indexes remained constant. What is likely true?
Life expectancy fell
Income inequality rose
Average years of schooling rose significantly
GNI per capita soared
The education index reflects schooling metrics. An improvement there while other components stayed constant implies a significant rise in average years of schooling or school enrollment.
If the bottom quintile's income share falls from 8% to 6%, what does this indicate?
Higher average incomes for all
Worsening income inequality
Reduced poverty depth
Improving income equality
A decline in the income share of the poorest 20% indicates that a smaller portion of total income goes to the lowest quintile, which signals increased inequality.
Which advantage does the Theil index have over the Gini coefficient?
It directly measures poverty
It ranges strictly between 0 and 1
It is simpler to compute by hand
It can be decomposed into within- and between-group inequality
The Theil index's main strength is its decomposability, allowing analysts to separate total inequality into within-group and between-group components.
During analysis, you notice GDP per capita increased but HDI decreased. Which is the most likely explanation?
The poverty rate fell
Gross enrollment rose
Inequality decreased
Life expectancy or education declined
The HDI includes life expectancy and education. If GDP per capita rises but HDI falls, at least one of those non-income dimensions must have deteriorated.
Which factor is NOT directly included in the HDI calculation?
GNI per capita
Mean years of schooling
Life expectancy at birth
Population growth rate
The HDI combines health (life expectancy), education (years of schooling), and income (GNI per capita). Population growth rate is not one of its dimensions.
If the area between the line of equality and the Lorenz curve is 0.18, what is the Gini coefficient?
0.36
0.09
0.18
0.82
The Gini coefficient equals twice the area between the line of equality and the Lorenz curve. Therefore, Gini = 2 Ã - 0.18 = 0.36.
A country's HDI uses a life expectancy index of 0.7, education index of 0.8, and income index of 0.9. What is its HDI (geometric mean)?
0.850
0.702
0.750
0.798
The HDI is the cube root of the product of its three dimension indexes: (0.7à - 0.8à - 0.9)^(1/3) ≈ (0.504)^(1/3) ≈ 0.798.
Which inequality measure can be decomposed into within- and between-group components?
Palma ratio
Theil index
Gross National Happiness index
Gini coefficient
The Theil index's key advantage is decomposability, allowing analysts to split total inequality into within-group and between-group parts, unlike the Gini or Palma ratio.
A poverty gap index of 15% implies which of the following?
Poverty fell by 15% last year
The average income is 15% above the poverty line
15% of the population is below the poverty line
On average, the poor are 15% below the poverty line
The poverty gap index measures the average shortfall of the poor from the poverty line, expressed as a percentage of that line. A 15% gap shows the depth of poverty.
When adjusting the HDI for inequality, which metric is used?
Multidimensional Poverty Index (MPI)
Gross Happiness Index
Gender Development Index (GDI)
Inequality-adjusted HDI (IHDI)
The Inequality-adjusted HDI (IHDI) penalizes the HDI value by accounting for inequality in each dimension, unlike other indexes that focus on gender or multidimensional poverty.

Cheat Sheet

  1. Understand Gross Domestic Product (GDP) - Think of GDP as the ultimate economic report card that adds up consumption, investment, government spending, and net exports to measure a country's total output. It's your go-to indicator for comparing who's sprinting ahead or lagging in economic growth. Gross Domestic Product (GDP) - IMF
  2. Explore the Human Development Index (HDI) - HDI is like a well-rounded student, combining life expectancy, education levels, and per-person income into one score that reflects overall well-being. By looking at HDI, you'll get a fuller picture of how people really live beyond just dollars and cents. Human Development Index (HDI) - UNDP
  3. Learn about the Gini Coefficient - The Gini Coefficient measures how evenly or unevenly income is spread out, with 0 meaning total equality and 1 meaning total disparity. Visualize it using the Lorenz curve to see whether wealth is cruising in the fast lane or stuck in traffic. Gini Coefficient - Wikipedia
  4. Analyze regional disparities in health metrics - Compare life expectancy and infant mortality rates across regions to uncover hidden health gaps. For example, you might spot why Sub-Saharan Africa often has lower life expectancy compared to Europe, helping you understand global health challenges. Life Expectancy - WHO
  5. Evaluate education disparities - Dive into literacy rates and school enrollment figures to map out educational inequalities around the world. You'll soon notice how higher literacy often correlates with higher HDI scores - education really is life-changing! Literacy - UNESCO
  6. Examine income distribution patterns - Break down income quintiles to see who's got the gold and who's barely scraping by. A big gap between the richest and poorest quintiles signals a tilted playing field that policies might need to level out. Income Share Held by Highest 20% - World Bank
  7. Identify global poverty trends - Track the share of people living below the $1.90/day poverty line to chart progress toward ending extreme poverty. Watching this trend over time tells you if global efforts are climbing uphill or making real strides. Poverty Overview - World Bank
  8. Apply quantitative reasoning - Crunch numbers like a pro by calculating growth rates, averages, and index comparisons to unlock the story hidden in raw data. Practice with real-world datasets to build your confidence and turn stats into clear insights. Statistics and Probability - Khan Academy
  9. Understand the impact of economic policies - Analyze how things like taxation, minimum wage, or social welfare shape development indicators. For instance, progressive taxes can narrow income gaps, while cuts in social spending might widen them - be the policy detective! Revenue Statistics - OECD
  10. Stay updated with current data - Keep your knowledge fresh by reviewing the latest global reports, dashboards, and statistical releases. Staying in the loop ensures your insights stay sharp and your arguments rock-solid. Human Development Reports - UNDP
