Dumanjug's population is characterized mainly by an increasing birth rate and a gradually declining mortality rate. The growth in population is thus attributed to higher rate of birth than of death.

The bulk of the household population is concentrated in the coastal barangays located in the western part of the municipality. The urban area comprising Poblacion, Sima, Ilaya, and Looc has the biggest slice of the population. Barangays Bitoon, Tangil, Tapon, Balaygtiki, Cogon and Liong are catching up with the urban barangays in terms of household population. With the urban area fast becoming a commercial hub, Bitoon, Paculob, Cogon and Liong are foreseen as upcoming dormitory communities.
