How to Compare Different Countries or States?
Key Point 1: Using Average Income or Per Capita Income
What is Per Capita Income?
- Per capita income is the average income of each person in a country or state for a given year.
- It is calculated by dividing the total income of the area by its total population.
Formula:
Per capita income = Total income of the area ÷ Total population
Why Do We Use Per Capita Income?
- It is a simple, easy, and widely accepted way to compare how rich or poor different countries (or states) are.
Examples:
-
Country A and Country B:
- Country A: Total income = ₹50,00,000, Population = 1,000
Per capita income = ₹50,00,000 ÷ 1,000 = ₹5,000
- Country B: Total income = ₹60,00,000, Population = 1,500
Per capita income = ₹60,00,000 ÷ 1,500 = ₹4,000
-
International Comparison (World Bank, 2020):
- USA (High Income): Per capita income is above $12,000
- Brazil (Middle Income): About $8,000
- Bangladesh (Low Income): Less than $1,060
-
Indian States:
- Goa (2019-20): Over ₹4 lakh per person
- Bihar: Less than ₹50,000 per person
Important Point:
- A higher per capita income means, on average, people have more money.
Key Point 2: Other Indicators of Development
1. Literacy Rate:
- It is the percentage of people (age 7 or above) who can read and write.
- Important because education directly affects development.
Examples:
- Kerala (2021): Literacy rate above 96%
- Bihar: About 63%
- International: South Africa (~87%) vs Niger (less than 20%)
2. Life Expectancy:
- The average number of years a person is expected to live at birth.
- Indicates health and medical facilities.
Examples:
- Japan: People live about 85 years on average
- India: Around 70 years
- Sierra Leone: About 54 years
3. Infant Mortality Rate (IMR):
- Number of babies dying before age 1 per 1,000 live births.
- Shows child health and healthcare quality.
Examples:
- Kerala: 6 deaths per 1,000
- Uttar Pradesh: 38 deaths per 1,000
4. Public Facilities:
- These are government-provided services like schools, hospitals, clean water, and transport.
Examples:
- Kerala: More government hospitals and schools per 1,000 people than Bihar
- In Europe, almost every house has piped water. In parts of Africa, people walk long distances for water.
5. Net Attendance Ratio:
- It is the percentage of children (say, age 6-10) attending school out of all children in the same age group.
Examples:
- If in a village, 80 out of 100 children (aged 6-10) go to school, net attendance ratio is 80%
Important Point:
- Development cannot be measured by money alone—education, health, and public services are equally important.
Key Point 3: Limitations of Using Only Per Capita Income
1. Inequality Hides in the Average:
- Average income does not tell us if income is equally shared or not.
Examples:
- Village Example:
- 5 people: 1 earns ₹95,000, others earn ₹1,250 each
- Total income = ₹95,000 + ₹1,250×4 = ₹1,00,000
- Per capita = ₹20,000 (misleading, since most are poor)
- A city with wide gaps: Rich few pull up the average even if most are poor.
2. Real World:
- Gulf countries: High per capita income due to oil, but foreign workers often live in poor conditions.
- USA: High average income, but some people lack access to good healthcare.
3. Does Not Reflect Quality of Life:
- Same average income, but different realities.
- Country 1: Healthy, educated, clean.
- Country 2: Poor health/literacy, pollution.
4. Hides Social and Regional Gaps:
- India's per capita income is rising, but some states (like Goa) are much richer than others (like Bihar).
- Girls may not go to school as much as boys, but per capita income does not show this.
Important Point:
- Per capita income is helpful, but not enough. We need to look at health, education, inequality, and facilities.
Activity: Compare Development of States in India Using Data
Step-by-Step Instructions:
- Take recent data for three states: Kerala, Bihar, and Himachal Pradesh.
- Write their per capita income, literacy rate, and infant mortality rate on the board.
- Discuss with the class which state seems most developed if we look only at income. Then discuss what changes if we look at all three indicators.
Observations:
- Kerala may not have the highest income, but it has the best health and education indicators.
- Bihar lags in all indicators.
- Himachal Pradesh does well in both education and income, but not as high as Kerala.
Conclusion:
- The state with the best combination of income, health, and education does better overall in development.
Summary Table
| Indicator | What it Shows | Example |
|---|
| Per Capita Income | Wealth (average) | Goa vs Bihar; USA vs Bangladesh |
| Literacy Rate | Education | Kerala > Bihar |
| Life Expectancy | Health | Japan 85 yrs; India 70 yrs |
| Infant Mortality Rate | Child Health | Kerala 6; UP 38 per 1,000 |
| Public Facilities | Basic Needs | Kerala has better facilities |
Conclusion
- Use many indicators to compare development.
- Per capita income alone is not enough.
- Focus on health, education, and equality too.
- The Human Development Index (HDI) is a good example; it combines income, life expectancy, and literacy.
True development improves the quality of everyone’s life—not just makes them richer!
Scenario Based Questions
Scenario 1:
You visit two states—Kerala and Bihar. Kerala’s per capita income is only a bit more than Bihar’s, but you see many more schools and hospitals.
Question: Which state is better developed and why?
Answer: Kerala is better developed because high quality of health and education is more important for people’s well-being, even if income differences are small.
Scenario 2:
Imagine a country has a very high per capita income, but most people are uneducated and unhealthy.
Question: Can this country be called developed? Why or why not?
Answer: No, because a country needs good education, health, and overall quality of life along with money to be truly developed.
Scenario 3:
You are a policy maker. The per capita income of your state is rising, but only a few people are benefiting.
Question: What can you do to ensure better development for all?
Answer: Invest in health, education, and provide public facilities so that everyone benefits, not just a few.
Scenario 4:
In your village, both boys and girls attend school, but many girls drop out after age 12.
Question: What could be done to improve true development in your village?
Answer: Improve girls’ access to secondary education through scholarships, transport, and awareness to support their continued schooling.
Scenario 5:
You meet a foreign student who says her country’s life expectancy is 82 years, but per capita income is lower than India’s.
Question: What might this tell you about her country?
Answer: Her country probably has better health and environmental conditions, despite not being the richest in terms of income.
