3. Worked Example

Question (Possible SI Exam):

Identify the state that has the highest per‑capita income in India and explain why it is considered a “high‑income” state.

Answer

• State: Gujarat
• Reason:
  1. Industrial Base – Heavy industries (steel, chemicals), petrochemicals, and a thriving textile sector.
  2. Agriculture – High productivity in cotton and groundnut, leading to export earnings.
  3. Infrastructure – Excellent road network (NH‑8, NH‑48), ports (Kandla), and special economic zones.
  4. Governance – Business‑friendly policies, lower GST rates, and robust tax compliance.
  5. Human Capital – High literacy rates and skilled labour force.

Relevance to policing:

• Rapid economic growth attracts migration; police must manage urban crowd control, property crimes, and labor disputes.
• Coastal ports demand robust maritime security.
