North India is a geographical region, loosely defined as a cultural region comprising the northern part of India (or historically, the Indian subcontinent) wherein Indo-Aryans (speaking Indo-Aryan languages) form the prominent majority population, while Tibeto-Burmans (speaking Tibeto-Burman languages) form the significant minority population. It extends from the Himalayan mountain range in the north to the Indo-Gangetic plains, the Thar Desert, till Central Highlands. It occupies nearly two-quarters of the area and population of India and includes one of the three mega cities of India: Delhi. In a more specific and administrative sense, North India can also be used to denote the northern Indo-Gangetic Plain within this broader expanse, to the Thar Desert.
Several major rivers flow through the region including the Indus, the Ganges, the Yamuna and the Narmada rivers. North India includes the states of Himachal Pradesh, Uttarakhand, Punjab and Haryana, Rajasthan, Uttar Pradesh, and union territories of Chandigarh, Delhi, Jammu and Kashmir and Ladakh. Occasionally, states of Western, Central and Eastern India are referred as "North Indian" in a broader term.
