Demography

Demography is concerned with the collection and analysis of data relating to population indicators and the interpretation of these data against social, biological, economic, political, geographical, ecological and historical background. It should be understood that population is the most important set of information for planning. It is the basis for determining the level of needs for public services. Population creates local demand for goods and services affecting the level of economic activities in sustaining their viable existence in an area

Population Composition

POPULATION BY AGE GROUP AND GENDER

Per 2010 census, total population is 65,493. Of this figure, 33,098 or 50.54% are males while 32,395 or 49.46% are females. Sex ratio therefore is 1:1.02 meaning for every 100 females there are 102 males. Hence there is a predominance of male population.

AGE DEPENDENCY RATIO

Age provides the basis for estimating population services/opportunities for different segments of population: school gong age, the dependent population, the employable group and the elderly.

For 2010, the dependent population, composed of the child and youth (0-14 years old) and those belonging to below 15 and those over 64 years old, total to 26,453 persons. The productive population or working age group total to 39,040 persons. Given these figures, total dependency ratio in 2010 is 1:0.68 meaning for every 100 productive individuals there are 68 dependent persons. Thus, the municipality is more of a provider.

Young dependency ratio is 61%; meaning there are 61 young dependents for every 100 productive population. The old dependency ratio is 7%; that is, 7 old dependents for every 100 working age group.

 

LABOR FORCE AND EMPLOYMENT

Labor Force or the economically active population refers to population 15 years old and above who are either employed or unemployed. Employed persons refer to those engaged in any of the major occupation. In 2010, there is a total of 39,040 labor force. Of this figure, 81.10% are employed and 18.9% are unemployed. Those who are employed may be on an employer-employee basis or self-employed and others are engaged in small –scale entrepreneurship. For 2012, as projected using the 2010 data, employed females total to 19,903 while males are 21,563. Of the unemployed, 4,200 are males and 3,637are females.

SCHOOL AGE POPULATION

School age population refers to the age of individuals who are supposed to go to school.

The advent of K-12 has brought a lot of adjustments to the Local Government Unit. It would only mean new classrooms, new facilities, new materials, new teachers, and perhaps new security. As the new guidelines set by DepEd, children who are 6 years of age must be in Grade 1 but it is also required that they undergo Pre-Scool orientation before they are accepted. So they spend elementary schooling from 12 to 16 years old. Grade 7 to 10 they are 13-16 years old. The remaining 2 years will be spent to TESDA-based education.

Around 19,563 belong to the elementary level and around 8,631 belong to the high school and TESDA-based levels From the groupings , it is estimated that around 10045 students are males and 9581 are females in the elementary, and around 4413 are males and 92284 are females in the secondary
levels.

Population Distribution

TOTAL POPULATION/TOTAL HOUSEHOLDS BY BARANGAY

Current (2012) population is 69,109 and households is 15,707. Urban population represents 17.54% of the total population while 82.46% represents the rural population.

Barangay Mapagong is considered an urban influence area because of its proximity to the Poblacion or the central business district. There are informal settlers along the railways of the PNR. Sil. Malicboy is thickly populated because of the presence of educational institutions in the area, aside from accessibity to transportation lines and in-migration . Barangay Ibabang Polo (4596) is also thickly populated since the coal-fired thermal plant is situated in the area.

As to the number of households, there are 2,718 urban households and 12,989 rural households. Urban average household size is 4.56 and rural average household size is 4.39.

Household Population by Urban and Rural Barangay and Average Household Size

 

Urbanization level is defined as growth in the proportion of a population living in urban areas which takes place when there is development. Where there are economic activities/opportunities in an area, in-migration occurs resulting in increasing population.

Urban population from 1990 to 2010 showed a decreasing trend. In 1990, about 26.75% of the total populated resides in the urban areas. Data in 2010 show that the urban population represents about 17.54% of the total population. Hence, the urbanization level shows a decreasing trend which could be attributed to out-migration. A good number of Pagbilaoins are going abroad and opted to migrate together with their families.

Population Projections and Estimates

Population projections are a basic requirement in planning. These projections are primarily used as basis for estimating future needs for basic services such as education and health services, determining level of demand for facilities and utilities, economic-related needs and corresponding spatial requirements, among others.

For this planning exercise, the combined use of geometric and participation rate methods were used. The derived growth rate of 1.54% was utilized in projecting the population up to the end of the planning period in 2022
