Ghaziabad is a city in the
Indian state of
Uttar Pradesh. It is sometimes referred to as the "Gateway of UP" because it is close to
New Delhi, on the main route into Uttar Pradesh. It is a part of the
National Capital Region of
Delhi. It is a large and planned industrial city, well connected by roads and railways, and is the administrative headquarters of
Ghaziabad District as well as being the primary commercial, industrial and educational centre of
western Uttar Pradesh and a major rail junction for
North India. Recent construction works have led to the city being described by a City Mayors Foundation survey as the second fastest-growing in the world. Situated in the Upper Gangetic Plains, the city has two major divisions separated by the
Hindon River, namely: Trans-Hindon on the west and Cis-Hindon on the east side. It is known for its high crime rate and for being the most polluted city in Uttar Pradesh.
