According to the 2011 Census of India, the population of the Solan municipal council area was 39,256. However, rapid urbanization and the recent expansion of the city limits to form a Municipal Corporation have pushed the estimated current population well over 50,000.
Solan has a diverse population comprising native Himachalis (Pahari speakers), Punjabis, and a large transient demographic of students and professionals from across India. The gender ratio in the district historically hovers around 880-900 females per 1,000 males, a metric the government has been actively working to improve. Hinduism is the dominant religion, with active Sikh, Muslim, and Christian minority communities. Literacy rates are high, typically exceeding 85%, largely due to the dense concentration of educational institutions in the region.
