Percentage of well paying jobs across BTech braches

Out of the **entire universe of all projected engineering jobs across all 30 fields combined**, what share does each field contribute specifically in the ₹15–25 LPA band?

This requires multiplying two things for each field — the **volume of total jobs** projected, and the **% of those jobs in the ₹15–25 band** — to get the actual count, then expressing each as a share of the grand total.

Here is the reasoning and output:

**The Volume Foundation**

India's tech ecosystem has over 5.4 million professionals in IT, product companies, and startups, making CSE the highest-demand engineering branch. [Plaksha University](https://plaksha.edu.in/blog/top-engineering-specializations-in-india-2026-btech-salary-career-guide) NASSCOM projects India will need over 11.5 million data science and AI professionals, with supply nowhere close to demand. [rank1st](https://rank1st.in/best-engineering-branch-2026/) Meanwhile, fields like mechanical and IT engineering expect 11–20% growth by 2033. [Education for All in India](https://educationforallinindia.com/vacant-engineering-seats-in-india-2025/) India produces 1.5 million engineering graduates annually [Business Standard](https://www.business-standard.com/finance/personal-finance/only-10-of-india-s-1-5-mn-engineering-graduates-set-to-secure-jobs-this-yr-124091600127_1.html) , but job volume across fields is wildly unequal.

The key insight: **CSE + Software Engineering alone account for nearly 45–50% of all engineering jobs in India.** Mechanical is the next largest in volume but heavily skewed to sub-₹15 LPA. Civil is enormous in headcount but almost entirely below this band. Fields like Astronautical, Nuclear, and Marine are tiny in total job count.

So when you compute each field's share of the ₹15–25 LPA superset, the result is very different from the previous analysis.

**Estimated Absolute Job Volumes (2026–2033, all new projected jobs) and ₹15–25 LPA share within the superset:**

The rough relative job volumes used (indexed, with CSE+Software as largest):

CSE: ~22% of all engineering jobs | Software Engg: ~12% | Mechanical: ~10% | Civil: ~8% | ECE: ~8% | Electrical: ~6% | Data Science: ~5% | AI/ML: ~4% | Chemical: ~3% | Automobile: ~3% | Biotech: ~2% | Robotics: ~2% | IoT: ~2% | Cloud: ~2% | Cybersecurity: ~2% | Industrial/Production: ~2% | Blockchain/Fintech: ~1% | Biomedical: ~1% | Semiconductor/VLSI: ~1% | Food Tech: ~1% | Agri Engg: ~1% | Environmental/Renewable: ~1% | Mining: ~0.8% | Marine/Naval: ~0.5% | Nuclear: ~0.5% | Mechatronics: ~0.5% | Textile: ~0.5% | Aerospace/Aero: ~0.5% | Astronautical: ~0.3% | Petroleum: ~0.7%

Multiplying each volume × its ₹15–25 LPA % from the previous analysis, then normalizing to 100% of the superset:

Now the picture tells a very different story. Here's what the numbers mean in plain language:

**CSE dominates at ~17.5%.** Despite having a wide salary spread (many jobs below ₹15 LPA in IT services, many above ₹25 LPA at product firms), the sheer volume of CSE jobs is so massive that even the 28% slice that falls in the ₹15–25 band translates to the largest absolute chunk of this income category nationally.

**Software Engineering follows at ~10.2%** for essentially the same reason — massive volume, moderate concentration in the band.

**Data Science punches well above its volume weight at ~9.8%.** It has a smaller total job pool than CSE or Mechanical, but a very high 35% of its jobs concentrate in this exact salary band — making it nearly equal to Software Engineering in absolute ₹15–25 LPA job count, despite being a fraction of the total job market.

**ECE at ~7.8%** reflects both high volume and reasonable band concentration. The semiconductor and 5G/6G wave will keep this elevated.

**AI/ML at ~5.1%** — only 16% of IT professionals currently possess AI skills, while 51% of AI/ML roles remain unfilled, with GenAI engineers facing a 53% demand-supply gap. [Zyoin](https://www.zyoin.com/post/indias-2026-job-predictions) This scarcity means AI/ML jobs are a smaller slice of the total pie, but they're high-quality, high-value positions — and a solid proportion of them land in the ₹15–25 band as mid-career roles.

**Mechanical Engineering at ~3.6%** — massive in volume but most of its jobs sit below ₹15 LPA. Only the EV, robotics-adjacent, and advanced manufacturing roles make it into this salary range.

**Civil Engineering is absent from this chart's meaningful contributors** — it has enormous job volume but almost none of it (only ~12%) reaches ₹15–25 LPA, so it contributes very little to the superset despite being one of the largest absolute headcount fields in India.

**Aerospace and Aeronautical at ~0.9%**, Astronautical at ~0.3%, Mining at ~0.2%, and Textile at ~0.5% are essentially marginal contributors to this income category when viewed as a share of all engineering jobs at this salary level — precisely validating your original observation about fields like astronautics having limited product-development engagement and correspondingly limited economic density in the middle-income professional band.

**The core insight:** The ₹15–25 LPA engineering job market over the next seven years will be almost entirely a tech-software-data story. CSE + Software + Data Science + ECE + AI/ML together will likely account for roughly **50% of all engineering jobs in this salary band** nationally, despite representing perhaps 40% of total engineering graduate output. The "traditional" fields — civil, mechanical, mining, textile — produce enormous graduate headcount but virtually none of it crystallizes into this income category at scale.
