UPSC CSE 2026 notification

What this covers

Tertiary activities provide services rather than transforming material inputs. Their locations respond strongly to demand, accessibility, connectivity, skills, information flows, institutions, amenities and trust. Some services must be near users; others can be delivered through digital networks but still cluster around talent, infrastructure and organizational ecosystems. Compare retail, transport, logistics, finance, tourism, education, health, administration and knowledge-intensive services.

Key ideas

  • Service demand threshold and range
  • Accessibility and centrality
  • Transport logistics and network nodes
  • Digital and communication connectivity
  • Skilled labour knowledge and institutions
  • Amenities reputation and trust
  • Clustering outsourcing and remote delivery
  • Public services equity resilience and regulation
