Most of the population of this region is confined to valleys and mid slopes of the hill ranges.
The area is totally rural with few rural service centers which are developed in urban characteristics.
Most of the population is concentrated on the valleys where as fertile agricultural land is available on the terraces.
Moderate concentration of population is found on the gentle slope convex spurs (mid slope).
Very sparse population with scattered settlements is located on the water divides and ridges.
Concentration of most of the population is in the valleys with lowest altitude.
As the altitude increases the distribution of population decreases, hence the hill ranges have less population compared to valley.
Since the very beginning the settlements were located near the source of water.
In the valley areas, dense population is the reason of, abundance of water in the form of perennial springs and rivers.
Lack of water resources on the high hill ranges are responsible for scattered settlements with low population density.
