Class 10 Social Science · Chapter 18
Short answer:
Development (Economics, Chapter 18 of Class 10 Social Science — pehla chapter Understanding Economic Development unit ka) yeh sikhata hai ki development ek hi cheez nahi hai — alag-alag logon ke liye alag matlab rakhti hai. Ek majdoor ke liye zyada mazdoori aur kaam ki suraksha development hai; ek kisan ke liye achhi fasal aur sinchai ka pakka intezaam; ek student ke liye achhi naukri aur behtar school.
Chapter teen bade ideas deta hai: (1) Per capita income se countries/states compare hote hain, lekin ye sirf average hai, distribution nahi dikhata. (2) Sirf income kaafi nahi — health, education, security, equal treatment jaise non-income factors bhi zaroori hain, isliye UNDP ne Human Development Index (HDI) banaya. (3) Development sustainable honi chahiye — Punjab ka groundwater level girna isi ka warning example hai.
Development chapter poore Class 10 Economics unit ki neev hai — is unit ke baaki chaar chapters (Sectors of Indian Economy, Money and Credit, Globalisation and the Indian Economy, Consumer Rights) sab isi base assumption par khade hain ki "development" ek single, seedha-saada target nahi hai jise sirf ek number se naapa ja sake.
Roz ki zindagi me hum "development" ka matlab bina soche use karte hain — naya highway ban gaya, GDP badh gaya, to development ho gayi. Yeh chapter is assumption ko todta hai: ek doctor ke liye development ka matlab alag hai, ek daily-wage majdoor ke liye alag, aur ek kisan ke liye bilkul alag. Isi vajah se income ke saath-saath education, health, equality aur environment ko bhi dekhna padta hai — aur yehi Human Development Index (HDI) ka base hai.
Yeh chapter conceptual hai, formula-heavy nahi — lekin ismein per capita income, IMR, literacy rate aur HDI jaise terms ki definitions aur unka comparative use bahut important hai, dono text-based questions aur case-based questions ke liye.
Chapter 18 Summary — 5 Minute Revision
1. Alag logon ke alag development goals
Ek hi cheez sabke liye development nahi ho sakti — kisan achhi paidawar aur sinchai chahta hai, majdoor saal-bhar kaam aur zyada mazdoori chahta hai, ameer farmer apne bete ko engineer banana chahta hai. Isliye development ka matlab define karte waqt kiske liye, kya price par — ye poochna zaroori hai. Ek group ke liye jo achha ho, doosre group ke liye woh nuksaandaayak ho sakta hai (jaise factory ka pradushan).
2. National development ke different notions
Alag log alag cheezon ko priority dete hain — kisi ke liye zyada income, kisi ke liye equal treatment aur azaadi. Mixed development goals hote hain jinme material cheezein (income) aur non-material cheezein (equality, freedom, respect) dono shaamil hain.
3. Average income / Per capita income
Countries ko compare karne ke liye average income (per capita income = total income ÷ total population) use hoti hai. World Bank isi ke basis par countries ko rich ($12,536 ya usse zyada, high-income) aur low-income ($1,135 ya kam) categorise karta hai (2018 World Development Report ke around figures) — India low-middle income group me aata hai.
4. Averages ki limitation
Average income distribution nahi dikhati — do states ka average income same ho sakta hai lekin ek me income barabar bant rahi ho aur doosre me bahut asamaan (unequal) — isliye sirf average income se poori tasveer nahi milti.
5. Income ke alawa doosre criteria
Sirf income kaafi nahi — log free se saans lena, pradushan-mukt paani, dawaiyon me milaavat na hona, bhedbhaav na hona jaisi cheezein bhi chahte hain jo bazaar se nahi milti, sarkar aur samaj se milti hain. Isliye public facilities (school, hospital) dekhna zaroori hai — jaise Kerala ka low Infant Mortality Rate (IMR) aur high literacy rate, jabki uska per capita income Punjab se kam hai.
6. Human Development Index (HDI)
UNDP (United Nations Development Programme) har saal Human Development Report publish karta hai jisme HDI diya jaata hai — teen indicators ka composite: (a) Life expectancy at birth (health), (b) Education level (mean + expected years of schooling), (c) Per capita income (PPP $ me, standard of living). Neighbouring countries me Sri Lanka ka HDI India, Pakistan aur Nepal se behtar hai kyunki health-education par public spending zyada hai.
7. Sustainability of Development
Development ko future generations ke liye bhi kaayam rehna chahiye. Punjab me groundwater ka level tezi se gir raha hai kyunki har saal jitna nikala ja raha hai utna recharge (barish/sinchai se) nahi ho raha — agar yehi trend chala to aane wali peedhi ke liye paani ka sankat khada ho jayega. Isliye natural resources ka overuse rokna aur unhe renewable rakhna development ka zaroori hissa hai.
In-Text Questions — Solutions
Neeche di gayi list me alag-alag logon ke development goals di gayi hain — ek kisan, ek majdoor, aur ek shehri ameer vyakti ke liye in goals ko match karo aur samjhao ki kis tarah ye ek-doosre se takra sakte hain.
Kisan chahta hai achhi sinchai, sahi rate par fasal ki bikri, aur karz me chhoot. Khet majdoor chahta hai saal-bhar kaam aur zyada mazdoori. Shehri ameer vyakti chahta hai apne bachchon ke liye achhi education aur unke naam par property.
Takraav: agar sarkar sinchai ke liye dam banati hai to kisan ko fayda hota hai, lekin usi dam se agar kisi gaanv ka displacement ho to wahan ke logon ka development chhinta hai. Isi tarah factory lagne se majdoor ko rozgaar milta hai lekin agar factory paani/hawa pradushit karti hai to aas-paas rehne walon ki health development peeche jaati hai. Isliye development ek group ke liye achha aur doosre ke liye bura ho sakta hai — yehi is chapter ka central idea hai.
Kya sabhi logon ke liye development ka matlab same hota hai? Reasoning do.
Nahi. Development ka matlab logon ke social aur economic circumstances par depend karta hai. Ek bekaar (unemployed) shehri educated yuva ke liye development ka matlab hai naukri, jabki ek kisan ke liye development ka matlab ho sakta hai achhi barish aur sinchai suvidha. Isliye same policy sabke liye "development" nahi la sakti — development goals define karte waqt yeh dekhna zaroori hai ki policy kis group ko fayda pahuncha rahi hai aur kis group ko nuksaan.
Averages ka istemal karna kyun zaroori hai? Kya averages sabhi comparisons ke liye equally useful hote hain?
Averages zaroori hain kyunki alag-alag states/countries ki total population alag hoti hai — sirf total income compare karna galat hoga (zyada population wale state ka total income zyada dikhega bhale hi per-person income kam ho). Average per capita income is problem ko theek karta hai.
Lekin averages har jagah equally useful nahi — jaise health aur education me sirf average nikalna kaafi nahi kyunki yeh distribution nahi dikhata (kitne log bahut peeche hain). Isliye income ke liye average chalta hai, par IMR/literacy rate jaise sensitive indicators ke saath saath equality/access bhi dekhni padti hai.
Punjab, Kerala aur Bihar ke per capita income aur unke development indicators (IMR, literacy rate) ka comparison karke bataiye ki sirf per capita income development ka poora paimana kyun nahi hai.
NCERT ki illustrative table dikhati hai ki Punjab ka per capita income Kerala se zyada tha, lekin Kerala ka IMR Punjab se kam aur literacy rate zyada tha. Bihar dono — income aur social indicators — me sabse peeche tha.
Iska matlab: agar sirf per capita income dekha jaaye to Punjab "zyada developed" lagega, lekin health aur education ke aadhar par Kerala ka development behtar hai. Isliye per capita income akela indicator hone ke bajaye ek starting point hai, poora paimana nahi.
IMR, aur literacy rate jaise indicators ko HDI banane me kyun use kiya jaata hai, sirf per capita income kyun nahi?
Per capita income sirf average material standard batata hai, lekin yeh nahi batata ki log kitne saal jeete hain, kitne educated hain, ya unhe basic services milti hain ya nahi. IMR aur life expectancy health status batate hain, literacy rate aur schooling years education status batate hain. Isliye UNDP ne HDI me income ke saath health aur education ko bhi jodkar ek composite, balanced measure banaya jo development ko zyada sahi tarike se dikhata hai.
Punjab me groundwater ke level me girawat kyun aa rahi hai, aur isse 'sustainability of development' ka kya sambandh hai?
Punjab me har saal jitna groundwater sinchai aur doosre uses ke liye nikala jaa raha hai, utna barish aur recharge se wapas nahi bhar paata — is wajah se water table lagatar neeche jaa raha hai. Agar yeh trend jaari raha to aane wale saalon me paani itni gehrai par chala jayega ki nikaalna mehenga ya asambhav ho jayega.
Yeh sustainability of development ka classic example hai: aaj ki development (zyada fasal, zyada income) agar natural resources ko is tarah khatam kare ki agli peedhi ke liye wahi resource bache hi na, to woh development sustainable nahi hai. Sustainable development ka matlab hai present zaroorat poori karna bina future generations ke resources ko khatra pahunchaye.

Exercise Questions — Solutions (Q1–Q8)
1. Development of a country can generally be determined by (a) its per capita income (b) its average literacy level (c) health status of its people (d) all the above. Justify your answer with reasoning.
Sahi jawab: (d) All the above.
Koi bhi ek akela indicator development ko poori tarah capture nahi karta:
- Per capita income sirf average hai — distribution ka pata nahi chalta.
- Literacy level batati hai log kitna educated hain, health ke baare me kuch nahi kehti.
- Health status (IMR, life expectancy) zaroori hai par income ke bina zindagi ki quality poori nahi hoti.
Isliye development ek multi-dimensional concept hai — yehi HDI jaise composite index banane ka reason hai jo teeno (income + education + health) ko saath combine karta hai.
2. Which of the following neighbouring countries has better performance in terms of Human Development Index — India, Sri Lanka, Nepal ya Pakistan? Kaunse factors is performance ko influence karte hain?
Sahi jawab: Sri Lanka. South Asia ke in neighbouring countries me Sri Lanka ka HDI rank India, Pakistan aur Nepal se behtar hai.
Reason: Sri Lanka ka per capita income India se kam hone ke bawajood uska overall performance behtar hai kyunki wahan health aur education par public spending zyada hai — life expectancy zyada, IMR kam, literacy rate zyada. Ye dikhata hai ki sirf income high hone se development guarantee nahi hoti — public facilities aur unka fair distribution bhi utna hi zaroori hai.
3. Assess the usefulness of the criteria used by the World Bank in classifying countries as rich or poor.
World Bank countries ko unke average per capita income (GNI) ke basis par classify karti hai — jinka per capita income zyada hai unhe rich/high-income aur jinka kam hai unhe low-income category me rakha jaata hai.
Usefulness: yeh ek simple, easily-available number hone se cross-country comparison aasan banata hai.
Limitation: yeh criterion sirf income dekhta hai, health, education, environment, ya income ke distribution ko nazarandaz karta hai. Do countries same average income ke saath bhi bahut alag development levels rakh sakte hain (jaise unequal distribution wala desh). Isliye World Bank ka criterion ek starting point hai, complete measure nahi.
4. In what respects is the criterion used by UNDP for measuring development different from the one used by the World Bank?
World Bank sirf per capita income (GNI) ko criterion banata hai. UNDP ka Human Development Index (HDI) teen cheezon ka composite hai:
- Life expectancy at birth — health ka indicator.
- Education level — mean years + expected years of schooling.
- Per capita income (PPP $) — standard of living.
Isliye UNDP ka measure zyada comprehensive hai kyunki yeh sirf income nahi, log kitni acchi zindagi jee paa rahe hain — unki health aur education bhi dekhta hai.
5. Why do we use averages? Are there any limitations to their use? Illustrate with your own examples related to development.
Averages zaroori hain kyunki alag-alag countries/states ki total population alag hoti hai — sirf total income se compare karna galat hoga, isliye per capita (average) income nikalte hain jo total income ko total population se divide karke milti hai.
Limitation: Average distribution ko chhupa deta hai. Udaharan: maano do gaanv A aur B ki average income same ₹10,000 hai. Gaanv A me sab logon ki income lagbhag ₹10,000 hai, lekin gaanv B me kuch log ₹90,000 kamate hain aur baaki logon ki income sirf ₹1,000 hai. Average dono me same hai, lekin gaanv B me asamaanta (inequality) bahut zyada hai. Isliye sirf average dekhkar development ka sahi andaza nahi lagaya ja sakta.
6. Kerala, jiska per capita income Haryana se kam hai, uska Infant Mortality Rate bhi kam hai. Kaise sambhav hai?
Yeh isliye sambhav hai kyunki IMR sirf income par nahi, health infrastructure aur public healthcare access par depend karta hai. Kerala ne decades se health aur education par bahut zyada public investment kiya hai — achhe hospitals, trained health workers, high literacy (jo mothers ko health-awareness deta hai). Isi wajah se, kam income hone ke bawajood, Kerala me infants ki mrityu dar kam hai. Yeh dikhata hai ki income high hona zaroori nahi ki achhi public services ho — sarkar ki priorities aur spending pattern equally important hain.
7. Why do you think the fertility rate in urban areas is lower than in rural areas?
Shehri (urban) areas me fertility rate kam hone ke reasons: (a) shiksha ka star zyada hota hai, khaaskar women education, jo family planning awareness badhaati hai; (b) women workforce me zyada participate karti hain, isliye late marriage aur kam bachche; (c) healthcare aur contraception ki access behtar hoti hai; (d) urban families me bachchon ko palne ka cost (education, housing) zyada hota hai, isliye log fewer bachche plan karte hain; (e) infant mortality kam hone se logon ko "zyada bachche paida karo taaki kuch bach jayein" wali soch ki zaroorat nahi padti.
8. Choose the most appropriate answer: The mean years of schooling in India is estimated as (i) 55 years (ii) 5.5 years (iii) 12 years (iv) 7.5 years.
Sahi jawab: (ii) 5.5 years — yeh NCERT me diya gaya illustrative figure hai jo Human Development Report ke education index component (mean years of schooling) ko dikhata hai. (Note: exact current figure UNDP report ke naye edition ke hisaab se update hoti rehti hai, exam me textbook ka diya figure hi use karo.)
Important Equations — Ek Nazar Me
| Term / Formula | Definition ya Calculation |
|---|---|
| Per Capita Income | Per Capita Income = Total Income of Country ÷ Total Population |
| Infant Mortality Rate (IMR) | IMR = (Infant deaths under 1 year ÷ Total live births) × 1000 |
| Literacy Rate | Literacy Rate (%) = (Literate population ÷ Total population age 7+) × 100 |
| Net Attendance Ratio (NAR) | NAR = (Students of relevant age-group attending school ÷ Total children of that age-group) × 100 |
| Human Development Index (HDI) | Composite of 3 indicators: (1) Life expectancy at birth, (2) Education (mean + expected years of schooling), (3) Per capita income (PPP $). Published yearly by UNDP in Human Development Report. |
| World Bank income classification | Countries classified as high-income / low-income based on average (per capita) income — not on health, education or environment. |
| Sustainability indicator (example) | Groundwater level (metres below ground) — agar withdrawal > recharge, level girta hai → development sustainable nahi. |

Common Mistakes — Yahan Marks Kat te Hain
- Per capita income ko hi 'development' samajh lena — yeh bhool jaana ki yeh sirf average hai, distribution nahi dikhata.
- HDI ke teeno components (life expectancy, education, income) ko yaad na rakhna, aur exam me sirf 'income aur education' likh dena, health chhoot jaana.
- World Bank ka criterion (sirf per capita income) aur UNDP ka criterion (HDI — income+health+education) ko ek hi samajh lena.
- 'Average' aur 'equal distribution' ko same maan lena — do states/gaanvon ka average income same ho sakta hai jabki unki inequality bilkul alag ho.
- Sustainability ko sirf 'environment protection' tak limit kar dena, jabki NCERT ka point hai ki development future generations ke liye bhi uplabdh honi chahiye — iska scope resources tak broad hai.
- IMR, literacy rate jaise indicators ki definitions me numerator/denominator ulat dena (jaise IMR ko 'total deaths ÷ live births' bina age-limit ke likh dena, jabki yeh sirf under-1-year infant deaths hai).
Board-Style Important Questions
- Development ke different notions par ek short paragraph likhiye, ek kisan aur ek shehri majdoor ke example ke saath.
- Per capita income aur Human Development Index (HDI) me antar spasht kijiye. Kaunsa zyada comprehensive measure hai aur kyun?
- Sri Lanka ka HDI India se behtar kyun hai jabki uska per capita income kam hai — explain kijiye.
- Sustainable development kya hai? Punjab ke groundwater ke example se samjhaiye.
- 'Averages kabhi-kabhi comparison ko misleading bana sakti hain' — ek numerical example ke saath is statement ko justify kijiye.
- Case-based question: ek passage diya jaata hai jisme do states ki per capita income, IMR aur literacy rate table di hoti hai — student ko poochha jaata hai ki kaunsa state 'zyada developed' hai aur kyun.
Aksar Poochhe Jaane Wale Sawaal
Class 10 Social Science ka syllabus 2026-27 me kitne chapters hain, aur Development kaunse number ka chapter hai?
2026-27 session ke rationalised NCERT syllabus me Class 10 Social Science me total 22 chapters hain — History 5, Geography 7, Political Science 5, Economics 5. Economics unit (Understanding Economic Development) sabse last aata hai, aur Development uska pehla chapter hai (overall chapter 18). Exact syllabus PDF ke liye ncert.nic.in ya apne school ka circular check karein.
Kya Development chapter me koi topic 2026-27 session ke liye deleted hai?
Nahi. 2023 ki rationalisation cycle ke baad Geography aur Economics ke sections me koi poora chapter delete nahi hua tha, aur 2026-27 session ke liye NCERT ne koi naya deletion notify nahi kiya hai. Development chapter poora syllabus me hai — agar koi source isko 'deleted' bata raha hai to woh purani (pre-2023) jaankari hai.
Development chapter ke important questions kaunse hain jo baar-baar poochhe jaate hain?
Sabse zyada aane wale question-types: (1) per capita income vs HDI ka difference, (2) Sri Lanka ka HDI India se behtar kyun hai, (3) sustainable development kya hai (Punjab groundwater example), (4) averages ki limitation ek numerical example ke saath. Neeche diye PYQ-style section me inke full answers hain.
Class 10 Social Science ke notes PDF ya important questions with answers kahan milenge?
Is page par diye gaye quick revision, summary, formulas table, aur exercise answers ko hi apna chapter-wise notes ki tarah use kar sakte ho — inhe copy karke apna khud ka PDF bana sakte ho revision ke liye. Poore syllabus ke liye NCERT ki official website (ncert.nic.in) se textbook PDF free download hoti hai.
Economics unit ke baaki chapters (Sectors of Indian Economy, Money and Credit) is Development chapter se kaise judte hain?
Development chapter woh base framework deta hai (income + non-income indicators + sustainability) jise baaki Economics chapters apply karte hain — Sectors of Indian Economy me hum dekhte hain ki kaunsa sector (primary/secondary/tertiary) zyada development de raha hai, Money and Credit me dekhte hain ki credit access development me kaise madad karta hai. Isliye Development ko achhe se samajhna baaki chapters ke liye foundation hai.
Board exam me is chapter se case-based ya numerical-type questions aate hain kya?
Haan — Development chapter me aksar ek table-based case study diya jaata hai (jaise do-teen states/countries ki per capita income, IMR, literacy rate) aur student se poochha jaata hai kaunsa zyada developed hai aur kyun. Isliye per capita income, IMR aur literacy rate ki definitions aur unko compare karne ka tareeka achhe se practice karo — is page ke formulas table aur intext section me yeh practice mil jayegi.
