Other barangays in the remote areas have a population less than 1,000 due to the lack of infrastructure support facilities like farm to market roads, electricity, water and communications plus the absence of the livelihood opportunities in the barangays.

The municipality is experiencing uneven distribution of population due to its physical characteristics such as topography and inadequate support facilities that are basic to the need of the populace.

It has an average household size of 5 persons, which is lower compared to other neighboring localities.
