Class 9 Geography Chapter 6: Population — 17 Important Questions with Complete Solutions

Population Chapter 6 is a core unit in the CBSE Class 9 Geography syllabus (India: People and Economy). The chapter tests three key competencies: (1) understanding demographic data interpretation—reading census data, population density maps, and age-sex pyramids; (2) calculating and comparing population growth rates; and (3) analyzing policy implications of population trends. In recent CBSE board exams, questions on population density (people per km²), natural growth rate, population composition by age, and the National Population Policy 2000 appear regularly in both Term 1 and Term 2 patterns. Short-answer questions often ask students to distinguish between birth rate and growth rate, or interpret a bar graph showing population distribution. Five-mark questions demand case-study analysis—for example, comparing population trends in two Indian states or explaining how the National Population Policy targets fertility rates. The 2026–27 board pattern emphasizes competency-based questions, meaning examiners will test your ability to read data, calculate rates, and apply concepts to real Indian demographic scenarios. Mastering these 17 questions ensures you can handle variations on exam day and score consistently across all three question types.

**Question 1:** According to the 2011 Census, which Indian state has the highest population density? (a) Uttar Pradesh (b) Bihar (c) West Bengal (d) Maharashtra **Answer:** (b) Bihar — 1,102 persons per km² (2011 Census), higher than West Bengal's 1,029 and Uttar Pradesh's 829. **Question 2:** Which of the following is NOT a component of population change? (a) Birth rate (b) Death rate (c) Migration (d) Literacy rate **Answer:** (d) Literacy rate — Population change = (Birth rate − Death rate) + Net migration. Literacy is a demographic characteristic, not a component of change. **Question 3:** The National Population Policy was adopted in which year? (a) 1995 (b) 2000 (c) 2005 (d) 2010 **Answer:** (b) 2000 — The National Population Policy (NPP) 2000 aims to achieve universal immunization, 100% female literacy, and reduce the total fertility rate to 2.1. **Question 4:** Population pyramid showing a narrow top indicates: (a) High mortality rate (b) Low fertility rate (c) High life expectancy (d) High population density **Answer:** (b) Low fertility rate — A narrow top (fewer children) combined with a broad base in developed countries reflects low birth and fertility rates, typical of aging populations. **Question 5:** Which formula correctly represents the crude birth rate (CBR)? (a) (Total births ÷ Total population) × 1,000 (b) (Total deaths ÷ Total population) × 1,000 (c) (Birth rate − Death rate) × 100 (d) (Total population ÷ Total area) × 1,000 **Answer:** (a) (Total births ÷ Total population) × 1,000 — CBR is expressed per 1,000 population. For example, if a country with 100 million people has 2 million births in a year, CBR = (2,000,000 ÷ 100,000,000) × 1,000 = 20 per 1,000.

**Question 1:** Define population density. Calculate the population density of India if its population in 2011 was 1.21 billion and area is 3.28 million km². **Answer:** Population density is the number of persons per unit area, usually expressed as persons per km². It is calculated as: Population density = Total population ÷ Total geographical area For India (2011): Population density = 1,210,000,000 ÷ 3,280,000 = 369 persons per km² (approximately) **Question 2:** Distinguish between birth rate and growth rate with one example each. **Answer:** Birth rate (BR) is the number of live births per 1,000 population in a year. Growth rate (GR) is the net change in population per 1,000 per year, calculated as (BR − DR) + Net migration, where DR is death rate. Example: India's birth rate (2020) ≈ 18 per 1,000, but growth rate ≈ 10 per 1,000 because death rate is ≈ 7 per 1,000, and migration is minimal. **Question 3:** State two objectives of the National Population Policy 2000. **Answer:** Two main objectives of NPP 2000 are: (1) To achieve universal immunization of children against vaccine-preventable diseases and provide universal school enrollment up to age 14; (2) To achieve 100% registration of births, deaths, marriages, and divorces, and reduce the infant mortality rate to below 30 per 1,000 live births and the maternal mortality ratio to below 100 per 100,000 live births. **Question 4:** Why is population composition important for planning in India? **Answer:** Population composition (age, sex, literacy, occupation) reveals the workforce potential, dependency ratio, and planning needs. An aging population (high proportion of elderly) requires more healthcare and pensions, while a young population (high proportion of 0–14 years) needs schools and job creation. Understanding literacy and occupation helps governments design skill development and employment policies. For India, the high proportion of people aged 15–59 (working-age) is an economic opportunity if they are skilled and employed. **Question 5:** What do age-sex pyramids reveal about a country's development level? **Answer:** Age-sex pyramids show the age and sex structure of a population at a point in time. A broad base and narrow top (triangular or pyramid shape) indicates high birth and death rates, typical of less-developed countries like India or Nigeria. A narrow base and broad middle (columnar shape) indicates low birth and death rates, typical of developed countries like Japan or Germany, reflecting high life expectancy and aging populations. These shapes help demographers assess fertility, mortality, life expectancy, and economic development.

**Question 1:** Explain why population distribution in India is uneven. Give two reasons with examples. **Answer:** India's population distribution is uneven due to varying physical, economic, and social factors. (1) Physical geography: The Indo-Gangetic Plain (covering parts of Punjab, Haryana, Uttar Pradesh, and Bihar) has fertile alluvial soils and abundant water, supporting high population density (>300 per km²). In contrast, the Deccan Plateau and desert regions (Rajasthan) are sparsely populated (<100 per km²) due to irregular rainfall and less fertile soils. (2) Economic development: Industrialized and urbanized regions attract migration and have higher densities. For example, Maharashtra (including Mumbai), Tamil Nadu (Chennai), and Gujarat have high population concentrations because of manufacturing, trade, and service sectors. Rural, agricultural states with limited industries have lower densities. As a result, 48% of India's population lives on just 5% of its land area. **Question 2:** What are the consequences of rapid population growth in India? Explain any three consequences. **Answer:** Rapid population growth creates multiple challenges: (1) Pressure on resources: Housing shortages, inadequate water supply, and food insecurity increase as the population expands faster than infrastructure. Urban areas face acute housing deficits and slum expansion. (2) Unemployment and underemployment: The labor force grows faster than job creation, especially in rural areas with limited non-agricultural employment. This leads to disguised unemployment and low incomes. (3) Educational strain: Schools and colleges cannot accommodate all children. Literacy rates remain lower in rural areas, and the quality of education declines due to overcrowding. (4) Environmental degradation: Deforestation, pollution, and resource depletion accelerate to meet the demands of a growing population, reducing sustainability. **Question 3:** Analyze how the National Population Policy 2000 addresses fertility rates in India. What are two specific measures mentioned in the policy? **Answer:** The NPP 2000 recognizes that high fertility rates (births per woman) drive population growth and limit development. The policy aims to reduce the Total Fertility Rate (TFR) to 2.1 by 2010 through targeted measures. (1) Promoting female education and empowerment: Higher female literacy and education delay marriage and childbearing, reduce TFR. The policy advocates 100% female literacy and universal school enrollment up to age 14, enabling women to make informed reproductive choices. (2) Providing universal access to family planning services: The policy ensures accessible, affordable contraceptive methods—pills, intra-uterine devices (IUDs), sterilization—and reproductive health counseling. It also mandates registration of all births and deaths to track progress. By 2020, India achieved TFR ≈ 2.2, closer to the replacement level (2.1), partly due to these interventions. **Question 4:** Describe the age-sex composition of India's population. How does it differ from developed countries like Japan? **Answer:** India's population is predominantly young, with approximately 27% aged 0–14 years, 68% aged 15–59 (working-age), and 5% aged 60+ years. In an age-sex pyramid, India shows a broad base (many children) tapering to a narrow top (fewer elderly), reflecting high fertility and relatively low life expectancy (≈71 years). Sex ratio is approximately 943 females per 1,000 males, skewed due to historical gender-based discrimination and mortality. In contrast, Japan has an aging population: <12% aged 0–14, ~60% aged 15–59, and >28% aged 60+. Japan's pyramid is columnar or inverted, indicating very low fertility (TFR ≈ 1.4), high life expectancy (≈84 years), and an aging workforce. These differences reflect economic development: India's young population is a demographic dividend if invested in education and employment; Japan's aging population faces labor shortages and pension pressures.

**Question 1:** Explain the concept of population growth rate. Calculate and compare the population growth rates of two Indian states using given data, and discuss the factors causing differences. **Full Solution:** Population growth rate (GR) measures the net change in population per 1,000 per year. It is calculated as: GR = (Births − Deaths) / Total population × 1,000 + Net migration component Or, GR = CBR − CDR + Net migration rate (per 1,000), where CBR is crude birth rate and CDR is crude death rate. **Comparison Example:** Let's take Uttar Pradesh (high growth) and Kerala (low growth) from recent census data. —Uttar Pradesh (2011 Census): Population: 199.8 million Birth rate: 29 per 1,000 Death rate: 8 per 1,000 Growth rate = 29 − 8 = 21 per 1,000 (or 2.1% per year) —Kerala (2011 Census): Population: 33.4 million Birth rate: 12 per 1,000 Death rate: 6 per 1,000 Growth rate = 12 − 6 = 6 per 1,000 (or 0.6% per year) **Factors causing differences:** (1) Fertility and education: Kerala has 94% literacy (highest in India) and universal female education, leading to delayed marriages and fewer children per woman (TFR ≈ 1.8). Uttar Pradesh has 67% literacy, lower female participation, and higher TFR (≈ 3.2), driving higher birth rates. (2) Healthcare and mortality: Kerala's advanced healthcare reduces infant and maternal mortality, but also lowers death rates. Uttar Pradesh's developing healthcare still shows higher death rates in some segments. (3) Economic development and urbanization: Kerala's high urbanization (47.7%) and service-based economy encourage smaller families. Uttar Pradesh's rural economy (77% rural) and agriculture-dependent livelihoods retain larger family preferences for agricultural labor. (4) Migration: Both states receive net migration, but Kerala's migration (out and in) balances, while UP gains migrants from poorer regions, slightly augmenting growth. Conclusion: UP's growth rate (2.1%) is 3.5 times higher than Kerala's (0.6%), reflecting differences in education, healthcare, economic structure, and social attitudes toward family size. --- **Question 2:** What is the National Population Policy 2000? Discuss its main objectives and any three specific strategies it proposes to achieve demographic goals. **Full Solution:** The National Population Policy (NPP) 2000 is a comprehensive government framework adopted by India to address rapid population growth and improve population quality. It recognizes that uncontrolled population growth strains resources, limits development, and perpetuates poverty. **Main Objectives:** (1) Stabilize population growth by reducing the Total Fertility Rate to 2.1 (replacement level) by 2010. (2) Ensure universal access to information, counseling, and services for fertility regulation. (3) Achieve 100% registration of births, deaths, marriages, and divorces. (4) Provide universal immunization of children against vaccine-preventable diseases. (5) Achieve universal school enrollment up to age 14, with special emphasis on female literacy. (6) Reduce infant mortality rate (IMR) to <30 per 1,000 live births and maternal mortality ratio (MMR) to <100 per 100,000 live births. **Three Specific Strategies:** (1) **Female Education and Empowerment:** The policy prioritizes 100% female literacy and universal primary education for girls. Educated women marry later, have fewer children, and make informed reproductive choices. Schools are mandated to provide sex education and health awareness. By 2020, female literacy rose to 70%, and TFR fell to ≈2.2. (2) **Reproductive and Maternal Health Services:** The policy ensures free and accessible family planning methods—condoms, pills, IUDs, sterilization (tubectomy, vasectomy)—through government clinics and camps. Maternal health is strengthened through antenatal care, institutional delivery support, and post-natal care to reduce MMR. Subsidized contraceptives and trained health workers in villages reduce cost barriers. (3) **Child Survival and Healthcare:** Universal immunization programs protect children against polio, measles, diphtheria, whooping cough, and tetanus. Higher child survival rates (achieved through vaccination and healthcare) reduce the pressure on parents to have many children, as fewer are needed to ensure family security. IMR improvements (from 55 in 2011 to ≈28 by 2020) correlate with falling fertility. **Impact:** India's TFR is now ≈2.2 (closer to replacement level), though unevenly distributed—Kerala (1.8) vs. Uttar Pradesh (3.2). The policy's success depends on sustained investment in education, healthcare, and gender equality. --- **Question 3:** Using a hypothetical population pyramid, explain how age and sex composition influences a country's economic and social planning. Discuss three planning areas affected by population composition. **Full Solution:** A population pyramid is a graphical representation of the age (horizontal bars for age groups) and sex (left for males, right for females) composition of a population. Its shape reveals critical insights for planning. **Hypothetical Pyramid Analysis:** Imagine two pyramids: —Pyramid A (Developing country like India): Broad base (high proportion of 0–14 years), tapering to narrow top. Sex ratio shows ~94 females per 100 males. —Pyramid B (Developed country like Germany): Narrow base (low proportion of 0–14 years), broad middle (high proportion of 15–59), and wide top (high proportion of 60+). Balanced sex ratio (100 females per 100 males). **Three Planning Areas Influenced:** (1) **Education and Skill Development:** Pyramid A's broad base means 27% of the population is school-age (5–14 years), requiring massive investment in schools, teachers, and learning materials. India must construct ~1.5 lakh schools and train millions of teachers to achieve universal enrollment. Curriculum must emphasize vocational skills for youth employment. Pyramid B's narrow base means fewer school-age children; Germany focuses on higher education and retraining older workers. (2) **Employment and Labor Market:** Pyramid A's 68% working-age population (15–59) is a demographic dividend—a large workforce. Planners must create millions of jobs annually. However, if education lags, unemployment rises. Pyramid B's shrinking working-age proportion (60% in Germany vs. 68% in India) creates labor shortages, forcing immigration and automation. India's challenge: employ 12–15 million young people annually; Germany's challenge: retain aging workers and attract migrants. (3) **Healthcare and Pension Systems:** Pyramid A's low proportion of elderly (5%) means less pressure on geriatric care and pensions. However, high proportion of children increases spending on maternal and child health, vaccination, and nutrition. Pyramid B's high proportion of elderly (28% in Japan, 21% in Germany) demands expanded geriatric services, nursing homes, and pensions, straining government budgets. Japan spends ~10% of GDP on pensions; India spends <1% because elderly are fewer but are increasingly becoming dependent on shrinking joint families. (4) **Gender Equality and Demographic Programs:** Pyramid A's skewed sex ratio (94 females per 100 males, vs. biological normal of 105) reflects gender discrimination (female infanticide, malnutrition, maternal mortality). Planners must invest in female education, healthcare, and legal protection. Pyramid B's balanced ratio reflects gender equality achievements. **Conclusion:** Population composition is a master variable shaping education, jobs, healthcare, pensions, and social stability for decades. India's young pyramid offers opportunity if investments in education and employment accelerate; postponed investment leads to an unemployed, unskilled youth bulge and social unrest.

**Question:** India's population grew from 846 million (1991) to 1.21 billion (2011), an increase of 364 million in two decades. Meanwhile, Kerala's population grew from 29.1 million to 33.4 million, an increase of only 4.3 million. Analyze the demographic transition in both regions and explain why Kerala is called a "demographic success story" while India faces population challenges. What lessons can be drawn from Kerala's experience for the rest of India? **Step-by-Step Solution:** **Step 1: Calculate and compare growth rates** —India: Growth = 364 million ÷ 846 million × 100 = 43% in 20 years ≈ 2.1% per year —Kerala: Growth = 4.3 million ÷ 29.1 million × 100 = 14.7% in 20 years ≈ 0.6% per year India's growth is 3.5× faster than Kerala's. **Step 2: Identify demographic transition stages** —Demographic Transition Model (DTM) shows 4 stages: Stage 1: High BR, high DR, low growth (pre-industrial) Stage 2: High BR, falling DR, rapid growth (early development) Stage 3: Falling BR, low DR, declining growth (late development) Stage 4: Low BR, low DR, stable/declining growth (developed) Keith's India (1991–2011): Transitioning from Stage 2 to Stage 3 → BR ≈ 26, DR ≈ 8, GR ≈ 1.8% Kerala: In Stage 4 → BR ≈ 12, DR ≈ 6, GR ≈ 0.6% **Step 3: Identify Kerala's "success" factors** (1) **Education:** 94% literacy (vs. India 74%), universal female schooling (94% female literacy vs. India 66%) → Women delay marriage, have fewer children (TFR 1.8 vs. India 2.6). (2) **Healthcare:** Infant Mortality Rate 12 per 1,000 (vs. India 40), Maternal Mortality Ratio 46 per 100,000 (vs. India 130) → Lower child mortality reduces need for large families for security. (3) **Urbanization:** 47.7% urban (vs. India 27%) → Urban lifestyles, smaller homes, and higher costs discourage large families. (4) **Economic development:** Per capita income ≈ ₹1.7 lakh (vs. India ≈ ₹0.9 lakh) → Higher incomes and service jobs reduce agricultural labor dependency, eliminating need for many children. (5) **Women's agency:** Mature population with more women in workforce (participation 29% vs. India 22%) and less gender discrimination (sex ratio 1,084 vs. India 943) → Better reproductive choices. (6) **Government policy:** Early adoption of family planning (1970s), reproductive health campaigns, and subsidized contraceptives normalized small families. **Step 4: Analyze consequences of differing growth rates** —India's 2.1% growth → Population doubling every 33 years. Without control, India could exceed 1.6 billion by 2050, straining food, water, jobs, education, and healthcare. Urban slums expand, rural unemployment persists, forest loss accelerates. —Kerala's 0.6% growth → Stable or declining population structure. Resources stretch further; schools and hospitals per capita are better. However, an aging population (12% aged 60+) creates new challenges: pension burdens, labor shortages, and need for elderly care. **Step 5: Draw lessons for India** (1) **Prioritize female education:** Every additional year of female schooling reduces TFR by ≈0.1–0.2. Kerala's 94% female literacy directly caused low fertility. India must enforce compulsory education for girls and remove barriers (poverty, child marriage, safety concerns). (2) **Strengthen rural healthcare:** 70% of India is rural; IMR in rural areas remains high (40–50). Mobile health camps, maternal health services, and child vaccinations in villages reduce child mortality, a key driver of high fertility. (3) **Empower women economically:** Kerala's high female workforce participation reflects economic opportunity and gender equality. Job creation in villages, microfinance for women entrepreneurs, and equal wages encourage smaller families. (4) **Normalize small families culturally:** Kerala's social acceptance of 1–2 children (vs. 3–4 in UP) took decades but is now normalized. India's National Population Policy must continue campaigns promoting small families as modern and desirable. (5) **Invest in urbanization and services:** Kerala's urbanization attracted industries (tea, spices, IT in Kochi), reducing agriculture dependency and enabling service-sector jobs compatible with smaller families. Planned urbanization in backward states (Bihar, Madhya Pradesh) could replicate this model. (6) **Strengthen contraceptive access:** Make family planning methods cost-free and culturally sensitive (addressing myths about sterilization, IUDs). Kerala's high contraceptive usage (52% vs. India 48%) enabled fertility control. **Conclusion:** Kerala achieved demographic transition to Stage 4 (developed-country pattern) through education, healthcare, economic opportunity, and female empowerment—the same pathway now being pursued nationally under NPP 2000. India's challenge: scaling Kerala's model across 28 states and 8 union territories, each with different cultural, economic, and educational contexts. The next 10 years (2025–35) are critical; if fertility stabilizes at 2.1–2.2, India avoids the population explosion of another 400 million; if it stays at 2.5, India's population could exceed 1.6 billion by 2050, worsening resource pressure.
