Least Populated Province of Pakistan: Balochistan

Balochistan is Pakistan's largest province by area (347,190 km²) but least populated, with ~12.3 million people (2023 estimate).

Low density reflects its arid, mountainous terrain, limited water, and underdeveloped infrastructure. Capital: Quetta. Other key centers: Gwadar (port), Turbat, Chaman.

By contrast, Punjab (~127M), Sindh (~55M), and Khyber Pakhtunkhwa (~40M) are far more populous.
