📖 PART A: Frequently Asked Questions (20 FAQs)
Questions students most commonly ask about Development.
-
Q: What is development? Why do different people have different goals for development?
A: Development is the process of improving the quality of all human lives by raising people's living standards, creating conditions for self-esteem, and increasing freedom and choice. People have different goals because their aspirations, needs, and situations vary. For example, a landless rural worker may want more work days, while a rich urban professional may want freedom from pollution.
-
Q: What are the common indicators used to measure development? List their limitations.
A: Common indicators: Income (Per Capita Income), Literacy Rate, Infant Mortality Rate, Life Expectancy, Net Attendance Ratio. Limitations: (1) They don't capture inequality (2) Ignore non-material aspects (freedom, security) (3) National averages hide regional disparities (4) Don't account for environmental degradation (5) May not reflect people's own perceptions of wellbeing.
-
Q: What is Per Capita Income? How is it calculated? What is its main limitation?
A: Per Capita Income (PCI) is the average income earned per person in a given area (country/state) in a specified year. It is calculated as: PCI = Total National Income / Total Population. Main limitation: It is an average that hides income distribution. A high PCI can coexist with extreme poverty if income is concentrated in few hands.
-
Q: Compare the developmental goals of a girl from a rich urban family and a boy from a poor rural family.
A: Girl (Rich Urban): May want freedom to choose her career, higher education abroad, a pollution-free environment, gender equality. Boy (Poor Rural): May want regular employment, good wages, education for siblings, electricity and water at home, freedom from debt and caste discrimination. Their goals differ due to their contrasting economic and social positions.
-
Q: What is the Human Development Index (HDI)? What are its three components?
A: HDI is a composite index published by the UNDP to measure a country's average achievement in three basic dimensions of human development: (1) Health: Measured by Life Expectancy at Birth. (2) Education: Measured by Mean Years of Schooling and Expected Years of Schooling. (3) Standard of Living: Measured by Gross National Income (GNI) per capita (PPP US$).
-
Q: Why is the concept of 'sustainable development' important?
A: Sustainable development means development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It is important because unchecked exploitation of resources for current growth leads to environmental degradation (pollution, resource depletion), which will harm the wellbeing and development options of future generations.
-
Q: What is the difference between economic growth and economic development?
A: Economic Growth: Narrow concept, refers only to increase in a country's output (GDP) or per capita income. Economic Development: Broader concept, includes growth plus progressive changes in socio-economic structure (reduction of poverty, inequality, unemployment) and improvement in quality of life (health, education).
-
Q: What is the significance of the 'Body Mass Index' (BMI) as a development indicator?
A: BMI is a measure of nutrition (weight in kg divided by square of height in meters). It indicates whether a person is undernourished (BMI below 18.5), normal, or overweight. A high proportion of undernourished people indicates poor developmental outcomes related to health and food security, even if income levels are rising.
-
Q: Why do we use averages (like PCI) for comparisons? What is the problem with them?
A: We use averages to get a single representative value for the entire population, making comparisons between countries/states easier. The problem is that an average conceals disparities. For example, India's per capita income hides the vast inequality between the income of a billionaire and a street vendor. It doesn't tell us how income is distributed.
-
Q: What is the Public Distribution System (PDS)? How does it contribute to development?
A: PDS is a government-run system that distributes subsidized food grains (rice, wheat) and other essentials to the poor through ration shops. It contributes to development by: (1) Ensuring food security (2) Fighting hunger and malnutrition (3) Stabilizing food prices (4) Providing a safety net for vulnerable sections, thus improving their health and productivity.
-
Q: Explain the terms 'developed country' and 'developing country' with examples.
A: Developed Countries: Have high per capita income, high HDI, advanced technological infrastructure, and dominant service/industrial sectors. Examples: USA, Japan, Germany. Developing Countries: Have lower per capita income, lower HDI, a large agricultural sector, and are in the process of industrialization. Examples: India, Bangladesh, Kenya.
-
Q: What is the importance of literacy rate in development?
A: Literacy rate is crucial because: (1) Educated people can make better use of health and other facilities. (2) It leads to a skilled workforce, boosting economic growth. (3) It empowers people (especially women) to fight exploitation and injustice. (4) It is essential for the functioning of democracy (informed citizens). (5) It correlates with lower infant mortality and better health.
-
Q: What is Infant Mortality Rate (IMR)? Why is it a sensitive indicator of development?
A: IMR is the number of infants dying before reaching one year of age, per 1000 live births in a given year. It is a sensitive indicator because it reflects: (1) The overall health and nutritional status of mothers and children (2) The effectiveness of the healthcare system (3) Level of sanitation and availability of clean drinking water (4) Social status of women. A high IMR signifies poor development.
-
Q: How can two countries with similar per capita income have different human development levels?
A: Because per capita income doesn't show how the income is spent. Country A may spend its income on arms and luxury goods for the rich, leading to low HDI. Country B with similar PCI may spend more on public health, education, and social security, leading to higher life expectancy, literacy, and thus a higher HDI. The composition of spending matters.
-
Q: What is the role of health in development?
A: Health plays a foundational role: (1) A healthy population is more productive, contributing to economic growth. (2) It reduces absenteeism and healthcare costs. (3) It ensures children can attend school regularly (link to education). (4) It improves the quality of life, which is a core objective of development. (5) Poor health perpetuates the cycle of poverty.
-
Q: What are the developmental goals of an adivasi from Narmada valley?
A: An adivasi (tribal) from the Narmada valley might prioritize: (1) Control over their traditional forest and land resources (2) Preservation of their cultural identity (3) Rehabilitation and fair compensation if displaced by dams (4) Access to education and healthcare that respects their way of life (5) Freedom from exploitation by outsiders.
-
Q: Why is the issue of sustainability important for development?
A: Unsustainable development (overuse of resources, pollution) may show high growth today but will cause environmental crises tomorrow (climate change, water scarcity, soil erosion). This will severely undermine the health, livelihoods, and security of future generations, effectively robbing them of their chance for development. Hence, sustainability is essential for long-term, genuine development.
-
Q: How do political freedom and dignity become developmental goals?
A: Development is not just about income. People seek: (1) Political Freedom: The right to vote, speak, and protest. This allows them to participate in decisions affecting their lives. (2) Dignity: Respect, freedom from discrimination (based on caste, gender, religion). Without these, even high income does not lead to a sense of wellbeing and fulfillment.
-
Q: What is the main criticism of using only income as a measure of development?
A: The main criticism is that income is a means to an end, not the end itself. The ends of development are long, healthy, creative lives and enjoyment of rights and freedoms. A person with high income but no political freedom, or living in a polluted area, is not necessarily "developed." Income alone cannot buy happiness, security, or clean air.
-
Q: What is the main takeaway from this chapter?
A: Development is a multi-dimensional concept involving not just income growth but improvements in health, education, equality, freedom, and sustainability. Different groups have different developmental goals. Therefore, we need better measures like HDI that go beyond per capita income. Most importantly, development must be sustainable and equitable to be meaningful.
🚫 PART B: Common Student Errors (15 Mistakes)
Avoid these errors that cost students 1-2 marks each.
Error 1: Equating "Development" with only "increase in income" or "economic growth".
Error 2: Writing "Per Capita Income = Total Income" - It's Total Income divided by Total Population.
Error 3: Confusing "Infant Mortality Rate" with "Maternal Mortality Rate". IMR is death of infants under 1 year.
Error 4: Spelling errors: "Sustainability" not "Sustainibility", "Mortality" not "Mortalilty".
Error 5: Stating "HDI is published by the World Bank" - It is published by the United Nations Development Programme (UNDP).
Error 6: Writing that "All people in a country have the same developmental goals".
Error 7: Confusing "Economic Growth" (quantitative) with "Economic Development" (quantitative + qualitative).
Error 8: Forgetting that "Net Attendance Ratio" is for children in school-going age, not literacy rate of adults.
Error 9: Saying "A high PCI country always has high HDI" - Not necessarily (e.g., Saudi Arabia vs Sri Lanka).
Error 10: Writing "BMI measures income levels" - It measures nutritional status (weight for height).
Error 11: Using "Developed" and "Rich" as perfect synonyms. A country can be rich in resources but have low HDI.
Error 12: Stating "Sustainable development means no development" - It means development that doesn't harm future prospects.
Error 13: Confusing "Life Expectancy" (average years a person is expected to live) with "Literacy Rate".
Error 14: Writing that "Public Distribution System (PDS) provides free education". PDS is for food grains.
Error 15: Forgetting the three components of HDI (Health, Education, Standard of Living).
💯 PART C: Score-Saving Tips (10 Tips)
Implement these to gain 5-10 extra marks in board exam.
Tip 1: Always start your answer by defining key terms: "Development is...", "Per Capita Income means...".
Tip 2: For "Compare goals" questions, create a table or use clear bullet points: "A girl from a rich family may want... while a boy from a poor family may want...".
Tip 3: Underline key terms and acronyms: PCI, HDI, IMR, BMI, PDS, UNDP, Sustainable Development.
Tip 4: Memorize the formula for PCI and the three components of HDI. These are often asked directly.
Tip 5: When asked about limitations of PCI/other indicators, give at least 3 points with brief explanations.
Tip 6: Use real-world examples: "For instance, Kerala has high HDI despite moderate PCI due to high literacy and health spending."
Tip 7: For sustainability questions, link to current issues: "Climate change shows why unsustainable development is dangerous."
Tip 8: Distinguish clearly between "what development is" (multi-dimensional) and "how it's measured" (indicators like HDI).
Tip 9: In numerical problems on PCI, show your calculation steps clearly: Total Income / Population = PCI.
Tip 10: Conclude answers by emphasizing that true development is about expanding human choices and capabilities, not just wealth.
