1 / 5Learning sections
Complete Concept Notes
All major ideas, indicators, comparisons, public facilities and sustainability concepts from the
chapter.
1Meaning of Development
Development or progress is about aspirations, desires and the ways people and societies work
towards better lives.
People ask what they need, how they should live together and whether life can be better for
all.
Development involves goals such as greater equality and improved quality of life.
Development is not only an economic idea; it also connects with history and political
science.
Core idea: Development is a broad process of improving people's lives and
achieving desired goals.
2Different People, Different Goals
People have different aspirations because their life situations, needs and priorities differ.
A landless rural labourer may want more days of work, better wages, education and freedom
from discrimination.
A prosperous farmer may seek assured income, better crop prices and opportunities for
children.
A rural woman may seek equal freedom, education and decision-making opportunities.
An unemployed urban youth may prioritise regular employment and security.
People from different social and economic groups can therefore define development
differently.
Important distinction: Different goals can also be conflicting goals.
3Conflicting Developmental Goals
What is development for one person or group may not be development for another and may even be
destructive for them.
Industrialists may favour large dams for electricity.
People displaced by dams, including tribals, may prefer smaller check dams or tanks.
A girl's desire for equal freedom may conflict with expectations within a household.
Exam point: Development must be evaluated from the perspectives of different
affected groups.
4Income and Other Goals
People want more income, but income alone does not capture everything important in life.
Material goals: regular work, better wages, decent prices, higher consumption.
Non-material goals: equal treatment, freedom, security, respect and dignity.
Some non-material goals can be more important than additional income.
Job choice may depend on family facilities, work atmosphere, learning opportunities, regular
employment and time for family.
Remember: A good development outcome is a mix of material and non-material
goals.
5National Development
When thinking about national development, different people can have different and conflicting
ideas about what India should achieve.
We must ask which goals are important and how conflicts between goals should be resolved.
A fair and just path should be considered.
We should ask whether a proposed development benefits a large number of people or only a
small group.
National development = thinking about collective goals, fairness, conflicts
and wider benefits.
6How Countries or States Are Compared
The criterion used for comparison depends on the purpose. For development, income is an important
starting point, but it is not sufficient.
Total income is not suitable for comparing countries with different populations.
Average income gives a more meaningful comparison of what an average person earns.
Per Capita Income = Total income of the country ÷ Total population
7Per Capita Income
Average income is also called per capita income. It is widely used to compare countries and
states.
The World Bank uses per capita income as a major criterion for classifying countries.
The chapter's 2024 figures identify high-income/rich countries at US$66,500 or above and
low-income countries at about US$2,300 or less.
The chapter states India's 2024 per capita income at about US$11,000, placing it in the
low-middle-income category.
Do not confuse total income with per capita income.
8Average Hides Inequality
Average income is useful but does not show how income is distributed among people.
Two countries can have the same average income but very different distributions.
A society with relatively equal incomes may be preferred over one where most people are poor
and one person is extremely rich.
Exam phrase: Average income hides disparities in the distribution of income.
9Income Is Not a Complete Indicator
Higher income does not automatically guarantee better health, education, safety or environmental
quality.
Money cannot by itself buy a pollution-free environment.
It cannot guarantee unadulterated medicines.
Protection from infectious diseases often requires community-level preventive action.
Public services can strongly influence quality of life.
10Development Indicators
The chapter uses several indicators to compare quality of life and human development.
Per Capita IncomeInfant Mortality RateLiteracy RateNet Attendance RatioLife ExpectancyMean Years of SchoolingGNI Per CapitaHDI
IMR: number of children dying before age one per 1,000 live births.
Literacy Rate: proportion of literate population in the 7-and-above age
group.
Net Attendance Ratio: children aged 15–17 attending school as a percentage
of all children in that age group.
Life Expectancy at birth: average expected length of life at the time of
birth.
11Haryana, Kerala and Bihar Comparison
The chapter demonstrates why per capita income should be considered alongside health and
education indicators.

Kerala has lower per capita income than Haryana but performs better on the
cited health and education indicators.
12Public Facilities
Many important goods and services are best provided collectively because collective provision can
be cheaper and more effective.
Examples include security, schools, healthcare and other basic facilities.
Government and society have a role in providing facilities so that people can access
essential services.
Girls' access to secondary education can depend on adequate public and social facilities.
The Public Distribution System can influence health and nutritional outcomes.
Key idea: Development depends not only on private income but also on access to
public facilities.
13Human Development
Once income is recognised as inadequate by itself, development is assessed through a broader
human-centred approach.
Health and education indicators are used along with income.
The UNDP's Human Development Report compares countries using educational levels, health
status and per capita income.
HDI stands for Human Development Index.
The chapter emphasises that what matters in development is what is happening to
citizens—their health and well-being.
14Human Development Data: India and Neighbours
The chapter's Table 1.6 uses GNI per capita, life expectancy, mean years of schooling and HDI
rank.

PPP note: the chapter explains that per capita income is expressed in dollars
in a way that makes purchasing power comparable across countries.
15Purchasing Power Parity (PPP)
PPP is used in international income comparisons so that a dollar represents comparable purchasing
power across countries.
The chapter uses GNI per capita in PPP dollars in its international comparison table.
The purpose is to make cross-country comparisons of income more meaningful.
16Nutrition and BMI
The chapter includes BMI as an activity for thinking about nutritional status.
BMI = Weight in kg ÷ (Height in metres)²
Students measure weight and height, convert height to metres and calculate BMI.
The chapter directs students to BMI-for-age tables to interpret nutritional status.
The activity explicitly asks students to discuss food and exercise without body shaming.
17Sustainability of Development
Development should not destroy the resources and environmental conditions required by future
generations.
The chapter warns that present types and levels of development may not be sustainable.
Environmental degradation is not confined by state or national boundaries.
Our future is linked together.
Memory line: Development must be desirable today and capable of being maintained
for future generations.
18Renewable Resources
Renewable resources can be replenished by nature, but they can still be overused.
Groundwater is an example of a renewable resource.
If groundwater extraction exceeds replenishment through rain, the resource is being
overused.
Thus, “renewable” does not mean “unlimited”.
19Groundwater Overuse
The chapter gives groundwater depletion as an example of unsustainable development.
About 300 districts had reported a water-level decline of over 4 metres during the previous
20 years cited by the chapter.
Nearly one-third of the country was overusing groundwater reserves.
If the trend continued, the chapter projected that 60% of the country could be doing the
same in another 25 years.
Overuse is particularly noted in agriculturally prosperous Punjab and western Uttar Pradesh,
hard-rock plateau areas, some coastal areas and rapidly growing urban settlements.
20Non-Renewable Resources
Non-renewable resources exist as a fixed stock and get exhausted after continued use because they
cannot be replenished by nature on the relevant human timescale.
Crude oil is the chapter's main example.
New discoveries can add to known reserves, but these too can eventually be exhausted.
Countries dependent on imports can face problems when international oil prices rise.
21Crude Oil and Resource Sustainability
The chapter's crude-oil table shows how long reserves would last if extraction continued at the
cited rate.

Sustainability question: Can a development path continue if it depends on
resources that are being exhausted?
22Big Picture of the Chapter
The chapter moves from individual aspirations to national development, from income to human
development, and finally to sustainability.
People: different goals and aspirations.
Comparison: income and per capita income.
Limitations: averages hide inequality and income misses many
quality-of-life dimensions.
Human development: health, education and income together.
Public facilities: collective provision supports quality of life.
Sustainability: development must protect future generations and natural
resources.

interpretation) · (resources and sustainable development) · (inequality and unsustainable
development).
🎯 Different People, Different Goals
Choose the response that best shows why development cannot be defined in exactly the same way
for everyone.
Recall: Different people can have different
aspirations, and some goals may conflict.
⚖️ Different or Conflicting?
Classify each situation by asking whether the goals are simply different or whether achieving
one goal can harm another.
Situation
Think about
One worker wants a regular job; another wants better opportunities for education.
Different goals
A large project gives electricity but displaces people living in the affected area.
Potentially conflicting goals
A person wants higher income as well as dignity and security at work.
Income + non-material goals
Exam skill: Explain the effect of one person's or
group's goal on another person's or group's goal.
🧩 Build a Development Goal Map
Take one hypothetical person and connect income with other goals. Select the goals that can
reasonably be part of a broader idea of development.
Think: A strong answer connects material goals with
non-material goals and access to public facilities.
➗ Per Capita Income Detective
Use the chapter's formula to solve the comparison.
Scenario: Country A has total income of ₹20,000 crore and
a population of 10 crore. Country B has total income of ₹30,000 crore and a population of 30
crore.
Formula: Per Capita Income = Total Income ÷ Total
Population.
📊 Average Does Not Mean Equality
Two societies can have the same average income but different distributions. Which conclusion
is safest?
Board phrase: Average income can hide disparities in
the distribution of income.
🔎 Which Indicator Should You Use?
Match the question with the most relevant indicator or group of indicators from the chapter.
Question
Relevant measure
What is the average income available per person?
Per Capita Income
How many children die before completing one year?
Infant Mortality Rate
What proportion of the 7-and-above population is literate?
Literacy Rate
How many children aged 15–17 are attending school?
Net Attendance Ratio
How long is a person expected to live at birth?
Life Expectancy at Birth
How can income, health and education be considered together?
Human Development approach / HDI
🇮🇳 Haryana vs Kerala vs Bihar
Use the chapter's table rather than income alone. Identify the strongest conclusion supported
by the data.
Data clue: Kerala has lower per capita income than
Haryana in the chapter's table but better cited IMR, literacy and attendance figures.
🧠 Data Interpretation: What Does the Table Tell You?
Read the chapter's state comparison and complete the reasoning.
Step 1: Compare Haryana and Kerala's per capita incomes.
Step 2: Compare their IMR, literacy and net attendance.
Step 3: Explain in 2–3 sentences why income alone is insufficient.
🌍 Human Development Index: Read the Pattern
Use the chapter's India-and-neighbours table. Look across GNI per capita, life expectancy,
mean years of schooling and HDI rank instead of using only one column.
Income+Health+Education→Broader human development picture
Analyse: Ask whether a country that does well on
income also necessarily has the same relative position on health, education and HDI.
🏫 Public Facilities Matter
Which statement best captures the chapter's argument?
Recall: Development depends not only on private income
but also on access to essential public facilities.
🍚 Nutrition and Economic Background
Development includes nutritional well-being. Think beyond the statement “food is available”.
Chapter link: Use the BMI activity and the chapter's
nutritional comparison questions to examine well-being.
📐 BMI Calculation Practice
Calculate BMI using the chapter's formula. Do not interpret the result using a generic adult
cut-off; the chapter directs students to BMI-for-age tables for interpretation.
Example: Weight = 50 kg; Height = 1.60 m.
Formula: BMI = Weight in kg ÷ (Height in metres)².
Interpretation in the chapter uses BMI-for-age tables.
📈 Rural–Urban and Male–Female Literacy Lens
The learning outcomes require interpretation of literacy differences across rural/urban and
male/female groups. Practise the reasoning without assuming that one average represents
every group.
RuralCompare the literacy figure with the urban figure
and describe the gap.
UrbanAsk what the comparison tells you about unequal
access and opportunities.
Male/FemaleCompare the two groups and identify whether a
disparity exists.
Do not overclaim: A data difference shows a
disparity; explaining its causes requires evidence.
💧 Renewable Does Not Mean Unlimited
Choose the best explanation for groundwater overuse.
Memory line: Renewable ≠ unlimited.
🛢️ Crude Oil Sustainability Check
Use the chapter's crude-oil table to reason about resource limits.
Connect: Non-renewable resources exist as a finite
stock and can eventually be exhausted.
🔗 Resource Use → Development → Future
Complete the causal chain. Explain how today's resource decisions can affect future
development.
Higher resource use→Possible depletion / environmental damage→Reduced options for future generations→Need for sustainable choices
🏛️ National Development Decision
A proposed project may create jobs and services but may also affect another group. What
should be examined before calling it “development”?
National development: Consider collective goals,
fairness, conflicting interests and wider benefits.
🧪 Indicator vs Conclusion
Pick the conclusion that correctly respects the limits of a single indicator.
Exam skill: State what the indicator measures, then
state what it does not capture.
✍️ 120-Word Chapter Synthesis
Write a concise answer to: “Why is development a broader idea than income?”
Include developmental goals, per capita income, inequality, health/education, public
facilities and sustainability.
Self-check: Have you explained both the usefulness
and limitation of income, included non-income indicators, and connected development with
future generations?
NCERT Exercises
All 13 end-of-chapter questions from the supplied NCERT 2026–27 chapter, arranged for practice.
1
NCERT EXERCISE · MCQ
Development of a country can generally be determined by:
i its per capita income
ii its average literacy level
iii health status of its people
iv all the above
Correct Answer: (iv) all the above.
Explanation: A country's overall development cannot be measured solely by income. True progress is multi-dimensional and combines economic growth (per capita income) with human capabilities, including educational attainment (literacy level) and health status (life expectancy / infant survival).
2
NCERT EXERCISE · MCQ
Which neighbouring country has better performance in terms of human development than India?
i Bangladesh
ii Sri Lanka
iii Nepal
iv Pakistan
Correct Answer: (ii) Sri Lanka.
Explanation: According to the UNDP Human Development Report (Table 1.6 in NCERT), Sri Lanka is ranked much higher than India in HDI due to significantly higher per capita income, higher life expectancy at birth (76.4 years), and higher mean years of schooling (11.1 years).
3
NCERT EXERCISE · MCQ
Four families have an average per capita income of ₹5,000. Three families earn ₹4,000, ₹7,000 and ₹3,000 respectively. Find the fourth family's income.
i ₹7,500
ii ₹3,000
iii ₹2,000
iv ₹6,000
Correct Answer: (iv) ₹6,000.
Calculation:
Total income of 4 families = 4 × ₹5,000 = ₹20,000.
Income of 3 given families = ₹4,000 + ₹7,000 + ₹3,000 = ₹14,000.
Income of the fourth family = ₹20,000 − ₹14,000 = ₹6,000.
4
NCERT EXERCISE · SHORT ANSWER
What is the main criterion used by the World Bank in classifying different countries? What are the limitations of this criterion, if any?
Model Solution:
Main Criterion: The World Bank uses Per Capita Income (Average Income) published in its World Development Reports to classify countries into High-income, Upper-middle, Lower-middle, and Low-income nations.
Limitations:
Hides Disparities: Averages do not tell us how income is distributed among people. A country may have a very high average income while the majority live in extreme poverty and a tiny elite controls most wealth.
Ignores Non-Income Factors: It overlooks essential components of human life such as health, literacy, longevity, personal security, equal treatment, and environmental sustainability.
5
NCERT EXERCISE · COMPARISON
In what respects is the criterion used by the UNDP for measuring development different from the one used by the World Bank?
Model Solution:
Scope of Indicators: The World Bank relies exclusively on economic wealth (Per Capita Income). The UNDP uses a composite index — the Human Development Index (HDI) — combining income with Health indicators (Life Expectancy at Birth) and Educational levels (Mean and Expected Years of Schooling).
Philosophy: The World Bank views monetary income as the sole end. The UNDP treats income as a means to achieve broader human well-being, freedom, and dignity.
6
NCERT EXERCISE · SHORT ANSWER
Why do we use averages? Are there any limitations to their use? Illustrate with your own examples related to development.
Model Solution:
Why We Use Averages: Averages are useful because they allow simple comparisons between groups or countries with different population sizes.
Limitations: An average hides inequality and distribution.
Example: Consider Country A where 5 citizens earn ₹10,000, ₹10,000, ₹10,000, ₹10,000, ₹10,000 (Average = ₹10,000). In Country B, 4 citizens earn ₹1,000 each and 1 citizen earns ₹46,000 (Average = ₹10,000). Both have identical average incomes, but Country A is equitable with no extreme poverty, whereas Country B is deeply unequal.
7
NCERT EXERCISE · CRITICAL THINKING
Kerala, with lower per capita income, has a better human development ranking than Haryana. Hence, per capita income is not a useful criterion at all and should not be used to compare states. Do you agree? Discuss.
Model Solution:
No, we do not fully agree. Per capita income is still a useful and necessary indicator because income provides the material means to afford nutrition, technology, infrastructure, and services.
However, per capita income cannot be the sole criterion. Money alone cannot buy a disease-free environment or ensure good public schooling unless collective public facilities exist. Kerala outperforms Haryana because of timely government investments in healthcare, literacy, and the Public Distribution System (PDS). Hence, income must be used alongside health and educational indicators.
8
NCERT EXERCISE · ANALYTICAL
Find out the present sources of energy used by people in India. What could be the other possibilities fifty years from now?
Model Solution:
Present Energy Sources: Coal, petroleum, diesel, natural gas, LPG, electricity generated through thermal power plants, biomass/firewood (in rural areas), and a growing share of solar, wind, and hydro energy.
Possibilities 50 Years from Now: Since fossil fuels (coal, crude oil) are finite non-renewable resources, future energy must rely heavily on clean and renewable alternatives:
Solar photovoltaic and concentrated solar thermal power
Offshore wind and green hydrogen technology
Safe nuclear fusion / advanced fission and tidal/geothermal power
Electric vehicles powered by renewable microgrids
9
NCERT EXERCISE · CONCEPTUAL
Why is the issue of sustainability important for development?
Model Solution:
Sustainability is essential because development that depletes natural resources or destroys the environment is self-defeating and cannot last. Sustainable development means “meeting the needs of the present without compromising the ability of future generations to meet their own needs.”
If groundwater is over-pumped or fossil fuels are exhausted today, economic growth will collapse tomorrow. Hence, sustainability ensures that progress is durable and long-lasting.
10
NCERT EXERCISE · VALUE BASED
“The Earth has enough resources to meet the needs of all but not enough to satisfy the greed of even one person.” How is this statement relevant to the discussion of development?
Model Solution:
This famous quote by Mahatma Gandhi underscores that nature provides abundant resources to satisfy human basic needs if used equitably and responsibly. However, when economic development is driven by mindless over-exploitation, consumerism, and greed, resources are depleted rapidly, creating severe ecological crises, global warming, and extreme inequalities.
It reminds us that true development requires conservation, sustainable consumption, and equitable sharing of resources among all citizens.
11
NCERT EXERCISE · APPLICATION
List a few examples of environmental degradation that you may have observed around you.
Model Solution:
Groundwater Depletion: Severe decline in underground water tables due to excessive tube-well pumping for agriculture and urban housing.
Air Pollution: Toxic air quality in cities caused by vehicular emissions, industrial smoke, and burning of crop residues.
Deforestation & Soil Erosion: Cutting down trees for road expansions and real estate, leading to topsoil loss and habitat destruction.
Water Body Contamination: Untreated domestic sewage and industrial effluents discharged directly into rivers, lakes, and drains.
Plastic Waste Accumulation: Clogging of urban drainage systems with single-use plastics and overflowing landfills.
12
NCERT EXERCISE · DATA ANALYSIS
For each item in Table 1.6, find out which country is at the top and which is at the bottom.
Model Solution (Based on NCERT Table 1.6 — Human Development Data):
Gross National Income (GNI) per capita (2017 PPP $): Top = Sri Lanka ($12,578) | Bottom = Nepal ($3,457) / Pakistan ($4,624).
Life Expectancy at birth (years): Top = Sri Lanka (76.4 years) | Bottom = Pakistan (66.1 years).
Mean Years of Schooling: Top = Sri Lanka (11.1 years) | Bottom = Myanmar (6.4 years) / Pakistan (4.5 years).
HDI Rank in the World: Top = Sri Lanka (Rank 73) | Bottom = Pakistan (Rank 161).
13
NCERT EXERCISE · DATA ANALYSIS
Using the BMI-below-normal table for India, compare Kerala and Madhya Pradesh. Can you guess why around one-fifth of people are undernourished even though there is enough food in the country?
Model Solution:
Comparison: In Kerala, the percentage of adults with below-normal BMI is among the lowest in India (~8.5% for males and ~10% for females), whereas in Madhya Pradesh, it is significantly higher (~28% for males and ~26% for females).
Reasons for Undernourishment despite Adequate Food:
Ineffective Distribution: Lack of well-functioning Public Distribution System (PDS) ration shops in poor states prevents affordable food from reaching remote rural poor.
Low Purchasing Power: Many poor families lack sufficient regular income to buy nutritious food (fruits, pulses, milk, vegetables).
Lack of Safe Drinking Water & Sanitation: Poor hygiene and recurrent infections cause malabsorption of nutrients in children and adults.

How to revise this chapter
First remember the framework, then the indicators, then the comparisons, and finally the
sustainability examples. Use the mnemonics below to recall the structure quickly.
🧠 Master Map — “G → I → H → S”
G — Goals: Different people have different and sometimes conflicting
developmental goals.
I — Income: Per capita income is useful, but averages can hide inequality.
H — Human Development: Health + education + income give a broader picture.
S — Sustainability: Development must remain possible for future
generations.
One-line recall: Goals → Income → Human Development →
Sustainability.
🎯 Different Goals — “I-R-S-F”
I — Income: Better wages, regular work, better prices.
R — Respect: Dignity and freedom from discrimination.
S — Security: Safe work and a secure environment.
F — Freedom: Equal opportunities and ability to make choices.
Exam trick: When asked “other than income”, immediately write
respect, security, freedom, equality and then give a suitable example.
⚡ Different vs Conflicting Goals
Different: Two people simply want different things.
Conflicting: Achieving one group's goal may harm or obstruct another
group's goal.
Classic chapter example: a large dam may provide electricity but can displace people.
Shortcut: Different = “not same”; Conflicting = “one can hurt
the other”.
➗ Per Capita Income — “Total ÷ People”
Per Capita Income = Total Income ÷ Total Population
It is also called average income.
It is more useful than total income for comparing countries with different populations.
The World Bank uses per capita income as a major criterion for country classification.
Numerical trick: If average and number of people are given →
Total income = Average × Population.
⚠️ Average Income — “Average ≠ Equality”
An average tells us the overall average but not the distribution.
Two societies can have the same average but very different income distributions.
Always mention disparity / distribution when asked for a limitation of
averages.
Board tip: Write one mini-example: “Most people poor + one
person extremely rich” can produce a high average.
📊 Development Indicators — “I-L-A-L”
I — Infant Mortality Rate: infant deaths per 1,000 live births.
L — Literacy Rate: proportion of literate population aged 7+.
A — Attendance: Net Attendance Ratio for the 15–17 age group.
L — Life Expectancy: expected length of life at birth.
Mnemonic:ILAL = Infant → Literacy →
Attendance → Life.
🏥 IMR — Remember the Direction
Lower IMR generally indicates better health conditions.
It counts deaths before one year of age.
Unit: per 1,000 live births.
Trap alert: Do not write “percentage” for IMR. The chapter
defines it per 1,000 live births.
🎓 Literacy vs Attendance
Literacy Rate: looks at the proportion of literate people in the
7-and-above age group.
Net Attendance Ratio: looks specifically at children aged 15–17 attending
school.
It exists in a finite stock and gets exhausted through continued use.
New discoveries can add to known reserves, but the resource remains exhaustible.
Memory: Renewable = replenished by nature; Non-renewable =
finite/exhaustible stock.
🧮 Data Question Strategy — “C-U-C”
C — Compare: identify the highest and lowest.
U — Understand: explain what the numbers mean.
C — Conclude: connect the data to development.
Example: Don't merely state Kerala's IMR is lower; conclude
that the cited data indicate better health outcomes.
✍️ 3-Mark Answer Formula — “D-E-C”
D — Define: give the key meaning/term.
E — Explain: explain the reason or mechanism.
C — Connect: connect it to the chapter's example.
Example: Define per capita income → explain why averages are
used → connect to country comparison.
📝 5-Mark Answer Formula — “P-E-E-C”
P — Point: directly answer the question.
E — Explain: give the reasoning.
E — Example: use a chapter example/data point.
C — Conclusion: link back to development.
Presentation tip: Use short paragraphs or numbered points
instead of one large block of text.
🚨 Common Exam Traps
Do not say per capita income is the only measure of development.
Do not say a higher average means every person is better off.
Do not confuse literacy rate with school attendance.
Do not treat renewable resources as unlimited.
Do not forget public facilities when discussing quality of life.
Do not discuss sustainability only in terms of money; include natural resources and future
generations.
⏱️ 60-Second Final Revision
Different people → different/conflicting goals.
Income matters → use per capita income.
Average can hide inequality.
Income alone is insufficient.
Mini Test
Three difficulty levels. Questions are based on the concepts and data in the supplied chapter.
1 mark
1. What is another name for average income?
Correct Answer: B. Per capita income.
1 mark
2. Which indicator measures infant deaths before the age of one year per 1,000 live births?
Correct Answer: B. Infant Mortality Rate (IMR).
1 mark
3. State one reason why people may have different developmental goals.
Suggested Answer: People live in different situations and have different needs, priorities, and aspirations.
1 mark
4. Is groundwater a renewable or non-renewable resource according to the chapter?
Correct Answer: Groundwater is a renewable resource, but it can still be overused and depleted if extraction exceeds natural replenishment.
2 marks
5. Write the formula for per capita income.
Correct Answer: Per Capita Income = Total Income of Country ÷ Total Population of Country.
2 marks
1. Two countries have the same average income. Why might one still be preferred over the other?
Suggested Answer: Average income doesn't show how wealth is distributed. One country might have an equitable income distribution where most citizens live well, while the other might have extreme disparity (most people poor and one person extremely rich).
3 marks
2. Haryana has higher per capita income than Kerala in the chapter's data, yet Kerala performs better on IMR, literacy and net attendance. What does this demonstrate?
Suggested Answer: It demonstrates that income alone is not an adequate measure of development. Health, education, access to basic public infrastructure, and collective welfare are crucial parts of real development.

3. Distinguish between different developmental goals and conflicting developmental goals.
Suggested Answer: Different goals mean different groups seek different targets based on their unique situations (e.g., landless labourers seeking wage employment vs rich urban youth seeking study abroad). Conflicting goals mean that achieving development for one group directly harms another group (e.g., dams providing power for industrialists while submerging lands and displacing tribals).

4. Why are public facilities important even for people who have income?
Suggested Answer: Individual purchasing power cannot buy collective benefits. Money cannot buy a pollution-free environment, ensure protection from infectious diseases, or build public safety networks. Provisioning these facilities collectively is also cheaper and more efficient.

5. Explain why “renewable” does not mean “unlimited”.
Suggested Answer: A resource is renewable because nature replenishes it (like rain replenishing groundwater). However, if our rate of extraction exceeds the natural replenishment rate, the stock declines. Hence, it can still face exhaustion if overused.

1. “Per capita income is useful, but it cannot be the sole measure of development.” Justify using the chapter's examples.
Suggested Answer: Per capita income (average income) is a single, measurable value that facilitates quick comparison, but it conceals major disparities and distributions of wealth. Furthermore, development is multi-dimensional and requires aspects like educational attainment (literacy, school attendance) and health indicators (IMR, life expectancy) which money cannot buy directly. The comparison of Haryana's high income vs Kerala's superior health and educational parameters is a prime chapter example of this limitation.

2. Explain the relationship among income, public facilities and human development.
Suggested Answer: High income provides individual families with purchasing power for private goods. However, public facilities (like schools, hospitals, public distribution systems) represent collective provisions that make vital services affordable and accessible to all. The availability of these public facilities directly improves health, literacy, and capabilities, which are the core parameters of human development. Therefore, income and public facilities are dual pillars required to achieve high human development.

3. A region increases groundwater extraction every year to raise agricultural output. Explain why this can create a development problem.
Suggested Answer: Increasing groundwater extraction to push agricultural yields leads to overuse if extraction exceeds natural recharge from rainfall. Over time, water tables fall dramatically, raising extraction costs, depleting the resource, and causing land subsidence or salinization. This creates a severe developmental problem by compromising water security, risking future agricultural failure, and destroying the resource base needed for future generations (unsustainable growth).

4. Compare the World Bank and UNDP approaches to development. Why is the UNDP approach broader?
Suggested Answer: The World Bank uses a single economic criterion, Per Capita Income (Average Income), to classify countries into development stages. In contrast, the UNDP uses the Human Development Index (HDI), which integrates economic income with life expectancy at birth (health indicator) and mean/expected years of schooling (education indicator). The UNDP approach is broader because development ultimately concerns expanding human capabilities, health, and literacy, rather than just raising monetary output. Income is viewed as a means to live a decent life, not the sole end.

5. “The future of development is linked to sustainability.” Explain with both renewable and non-renewable resource examples from the chapter.
Suggested Answer: Sustainability means development that meets present needs without compromising the ability of future generations to meet theirs.
1. Renewable Resources (Groundwater): These are replenished by nature. However, if overused (extraction exceeds recharge), water tables collapse, creating scarcity. Thus, renewable resources require sustainable limits.
2. Non-Renewable Resources (Crude Oil): These exist in a finite stock and cannot be replaced once exhausted. If we consume crude oil rapidly without moving to renewable energy, future generations will face severe energy crises.
Therefore, to keep development going, we must manage resources efficiently, shift to renewable options, and minimize ecological damage.
