Population means an organised form of people living together in a certain place having certain social norms and values.
The population of the world before Christ was 25 million at that time 15 million were engaged in agriculture. In 1659 AD population increased to 59 million. Likewise in 1850 AD-1 billion, in 1930 AD-2 billion, in 1975 AD- 4 billion, in 1998 AD about 6 billion and at present 7 billion.
Distribution of population means a total number of people living in different geographical regions.in
It also has its own importance. They are as follows:
Reasons for having less population in Far development region:
The population growth rate for mountain and hill has increased and it has slightly reserved for Terai. The population growth rate for the Terai in 2011 BS was 1.72 %. The mountain and hilly regions have lower PGR than the Terai region. The high growth of population in the Terai region is due to the migration from mountain, hill and flow of immigrant from the neighbouring countries.
The population is unevenly distributed according to geographical region. Mountain region contains 35% of the land, although the population is only 7.5%. In the hilly region, the population is 45%, though its area is 42%, and in the Terai region, it has only 23% land but the population is 46%.
Causes of unequal distribution of population in Nepal

Population density is calculated by the following formula:
Population density = population/area per sq. km.
Population density differs because of:
