Ek tokri, do sach: gaon-shehar aur khaane ki mehangai
Desh ki mehangai 5.54% — par gaon mein 6.08% aur shehar mein 4.88%. Ek desh, ek mahina, phir alag number kyun?
Socho pehle… phir dekho jawab
Kyunki CPI ek weighted average hai. Har ghar ki tokri alag hai: gaon ki tokri mein khaane ka hissa bada, isliye jab khaana mehnga hota hai toh gaon ka number zyada uchhalta hai.
Mechanism: CPI = tokri ki har cheez ke price index ka weighted average; weight = parivaar ke kul kharch mein us cheez ka hissa. Saalana mehangai = (is saal ka CPI − pichhle saal ka CPI) ÷ pichhle saal ka CPI × 100. Naye series ka base year 2024 (=100) hai; tokri ke 12 vibhaag (divisions) hain.
September 2026 (card): headline 5.54%, khaana 7.74%, gaon 6.08%, shehar 4.88%; gaon ki khaane ki mehangai 8.06% aur shehar ki 7.18%. ICRA ke anusaar 71 basis point ki badhat mein se 62 khaane se aaye.
Kise zyada chubhti hai: jis parivaar ki aamdani ka bada hissa khaane par jaata hai — aksar gareeb aur bhoomiheen majdoor. Mehnga anaaj usi kisan ko faayda deta hai jiske paas bechne ko bachat ho.
Average ka sabak: ek national number sabka sach nahi batata. Card ke anusaar Tamil Nadu (6.81%) aur Odisha (6.70%) mein mehangai desh ke average se zyada thi.
Ghar pe try karo
Ek 'mini CPI' banao: khaana (weight 50%, badhat 8%), kiraya (25%, 3%), yaatra (15%, 4%), baaki (10%, 2%). Weighted average nikalo (jawab lagbhag 5.55% aana chahiye). Phir khaane ka weight 60% aur kiraye ka 15% karke dobara nikalo — number kitna badla?
Wow!
Basis point = 0.01 pratishat-ank. 4.83% se 5.54% ki chhalaang = 71 basis point!
3 sawaal
- September 2026 mein gaon ki mehangai shehar se zyada kyun thi?
Jawab dekho
Gaon ki tokri mein khaane ka hissa (weight) bada hai. Khaane ki mehangai tez thi, aur gaon ki tokri mein khaane ka weight zyada hai.
- 4.83% se 5.54% hone par kitne basis point ki badhat?
Jawab dekho
71. 0.71 pratishat-ank = 71 basis point.
- CPI ke naye series ka base year kya hai?
Jawab dekho
2024. Naye series ka base year 2024 = 100 hai.
