Haryana is one of the 29 states in India, situated in North India. It was carved out of the former state of East Punjab on 1 November 1966 on a linguistic basis. It stands 21st in terms of its area, which is spread about 44,212 km2 (17,070 sq mi). As of 2011 census of India, the state is eighteenth largest by population with 25,353,081 inhabitants.

Haryana is one of the wealthier states of India and had the second highest per capita income in the country at ₹119158 (US$1,800) in the year 2012–13 (See List of Indian states by GDP) and ₹132089 (US$2,000) in the year 2013–14, including the largest number of rural crorepatis in India. Haryana is also one of the most economically developed regions in South Asia, and its agricultural and manufacturing industries have experienced sustained growth since the 1970s. Since 2000, the state has emerged as the largest recipient of investment per capita in India.

It is bordered by Punjab and Himachal Pradesh to the north, and by Rajasthan to the west and south. The river Yamuna defines its eastern border with Uttar Pradesh. Haryana surrounds the country’s capital Delhi on three sides, forming the northern, western and southern borders of Delhi. Consequently, a large area of south Haryana is included in the National Capital Region for purposes of planning for development.
