North India in a broader geographic context, refers to the northern part of India or, historically of the Indian subcontinent, occupying 72.6% of India's total land area and 75% of India's population wherein Indo-Aryans form a prominent majority population. The region has a varied geography ranging from the Indo-Gangetic Plain and the Himalayas, to the Thar Desert, the Central Highlands and the north-western portion of the Deccan plateau. Multiple rivers flow through this region including the Ganges, the Yamuna, the Indus and the Narmada rivers. In a more specific and sometimes administrative sense, North India can also be used to denote the Indo-Gangetic Plain within this broader expanse, stretching from the Ganga-Yamuna Doab to the Thar Desert.
