According to the Population Census of 2001, the population of the Gurungs is 543,571 consisting 2.43% of the total population of Nepal standing at 23,151,423 The Gurungs were originally nomadic hunters, and engaged in highland pastoralism. It now has the highest percentage of migration among the ethnic groups of Nepal. This is due to the scarcity of food, economic imbalance, and the environmental pressures in the high hills. In order to cope with the situation, a big number of Gurungs migrated to different parts of Nepal including the low lands of Terai.
