The main occupation in Mewat is agriculture along with allied and agro-based activities. The Meos are the predominant population group and are all agriculturists. Agriculture is mostly rain fed except in small pockets where canal irrigation is available. Agriculture production measured in terms of crop yield per hectare is low in comparison to the other districts of the State. Animal husbandry, particularly dairy, is the secondary source of income for the people and those who live closer to the hilly ranges of Aravali also keep sheep and goats. Milk yields are not so low, however, due to heavy indebtedness most of the farmers are forced to sell the milk to the lenders at lower than normal price, which drastically reduces their income from the milk. The poultry population in Mewat is much less in comparison to other districts of Haryana State.
