Agriculture is the primary vocation of its residents. Agricultural land is very fertile, but the farming is still on the old pattern and dependent upon the natural rainwater. Proper arrangement of irrigation, scientific technique of farming, and good quality of seeds and proper availability of fertilizer is still not available. Farming land is not sufficient for the densely populated village and also the land area is not sufficient to feed and engage such a large population. Livestock and Animal Husbandry are the other major occupations ancillary to agricultural activities. Fisheries are another occupation due to abundant water reservoir available in the form of various ponds. There are around 20 small and large ponds available in the village.

On the south-eastern side of the village Division-2 office of the water ways along with Inspection Bungalow (IB) of irrigation department is an important establishment for flood control and other activities related to water resources. Executive Engineer level officer heads this division. In 1957 a dike on the western and eastern side of Kamla Balan River was made to protect the surrounding area from the flood. Western dike is passing from the eastern side of Naruar. In 1987 this elevated dike was broken from many places due to overflow of water surpassing all previous records. Naruar was one of the many villages which suffered severe loss due to this natural calamity.

Still the industrialisation is to be initiated in the area, even the sugar mills and some cotton mills situated at around 10-15 kms from Naruar are closed. Some of the residents are engaged in the business in the village and the nearby Jhanjharpur Market. As per census 2011 report around 3266 persons were workmen as main and marginal workers.

Facilities like roads, electricity, drinking water and toilet has been improved nowadays, but still a lot is to be done in this field. Apart from street roads one main road passes through the village from south to north and it is the main connecting road of the village.

Mango trees are abundant in Naruar and it is also an important seasonal occupation of cash crop for the villagers.

Brain drain is the major area of concern for the village due to lack of proper opportunities in the State. Most of the educated and even uneducated youths of the village are staying outside the state for the education and source of living.
