Population distribution by ecological zones

The country is divided into three ecological zones. Mountains, Hills and Terai zone. Due to the diversity in land structure, soil, natural resources, and means, the population distribution in Nepal is unequal. The area with educational facility, health service, job opportunity, and transport and communication service has a thick population, and the area deprived of these facilities has a thin population. According to the census of 1952/54, the hilly belt occupied 64.8% whereas terai belt occupy 35.5%of the population. After the census of 1961, the population of the hilly belt has declined and the population of terai has increased. The census of 1981 shows the decline of population by 7%in mountains and hills and increase in population by 7% in terai. Similarly in census 1991, the population in mountains and hilly belts declined by 3%and there is an increase of 3% in terai. The major reasons for the increase in population in terai are the Malaria eradication, the alluvial soil, good climate, employment opportunities and transport facilities.
