DEMOGRAPHIC CHARACTERISTICS

Population      

The 1995 census on population figured the population of Ivisan at 22,720. It has  increased by 1,210 in a span of five (5) years as presented in  Table 8. The municipality’s population size ranked 15^th among the 16 municipalities in the province. It  comprises 3.6 percent of the province’s population and contributes 0.4 percent to the region’s overall figure.

Gross Density            

With the total population of 22,720 and land area of 54.20 square kilometers (sq. km.) or 5,420 hectares, the population density of the municipality is at 419.19 persons/sq. km or 4.192 persons/hectare (Table 9). There is a recorded increase of 22.33 from the 1990 density which is at 396.86 persons/sq. km. (3.9686 persons/hectare) and an increase of 97.90 from the 1980 density. With the present figure, Ivisan is classified as a low density area.

Population density per barangay is presented in Figure 14. The population density standard set by HLRB classifies below 150 persons per hectare as  low density area. Based on this standard, all barangays within the municipality are classified as low density areas. The urban center have relatively higher densities at 31.369 and 13.618 persons per hectare for Poblacion Sur and Poblacion Norte respectively. Rural barangay with the highest population density is Basiao with 10.73 persons/hectare. Basiao serves as a growth center of the municipality  with facilities such as the fishing port, public market, filling station  and other services. Barangays with the least densities are Agustin Navarra at  1.562 persons/hectare followed by Cabugao at 1.916 persons/hectare. Both barangays have higher slopes and is utilized as the watershed area of the municipality.

 Should the population continue to increase at its present rate, Ivisan would still be a low density municipality by the year 2006. By then the projected population density of Ivisan will be at 4.69 persons/hectare or an increase of 0.5 persons per hectare over a period of ten years. This figure however could change should Ivisan serve as the alternative residential area for people working in the provincial capital.

Annual Population Growth , Birth and Death Rate and Migration

The average growth rate registered between the year 1990 to 1995 is 1.03 percent showing a downward trend compared to the 1980 to 1990 which is 2.13 percent and 1970 to 1980 which is 2.15 percent (Table 8 and Figure  15). The crude birth rate during the same year is 23.40 percent while the crude death rate is only 4.80 percent (Table  ). It could be noted that despite the high birth rate and the low death rate, the registered growth rate is still low. This could be influenced by the out migration of residents. Young people especially those that were able to  complete their high school and college education opt to go to big cities within and outside of the country to look for employment opportunities which is very scarce in the municipality. No record, however, is available as to the actual number of people who actually migrated out of Ivisan.

Population in 1990 is 21,510 and increased to 22,720 in 1995. At 1.03 growth rate the population is projected to reach 25,431 in 2006 as presented in Table 10. The projected population growth by barangay as presented shows Poblacion Norte having the highest figure and Agustin Navarra having the lowest figure by the year 2006.

Age Structure

            The 1995 Census on Population shows a relatively young population with ages 0 - 14 years old comprising 41.23 percent of the total figure  (Table 11). A total of 53.85 percent falls under the productive age group (15-64) and 4.92 percent belong to the older (65 and over) age group.  Dependent population   (0-14 and 65 and above) age group totals to 10,484 or 46.15 percent of the total population. This scenario indicates that for every 100 productive population there are 84.32  dependent population. The percentage of dependent population increased from 39.09 percent in 1980 by 7.06 percent in 1995.

There is an increase in the percentage of younger population in 1995 as compared to the 1980’s  which is only 36.77 percent and a decrease in percentage in the productive population which was recorded at 60.91 percent in 1980

            Projection of population by age group is presented in Table 12. Under normal conditions the same trend could be observed during the next ten years.

Sex Structure

            There are more males than females in 1995 with a ratio of 103.16:100 as  presented in Table 11. This also holds true in  1980 where  survey result showed a ratio of 101.8 male to every 100 female. Figure 16 shows a graphical presentation of the population by sexes and age group. The figure indicates that from ages 0-34 and 40-44 age group there is a consistent dominance of male population but this dramatically change at age group 45 and above where there are more female than the male population. This figure could be indicative that the female population has a longer life span than their  male counterpart or this could also be due to out migration. Culturally, women are left at home while men go out to look for livelihood opportunities outside of the municipality.

Urban-Rural Population Distribution

            Of the total population in 1995, 80.48 percent resided in the rural areas while 19.52 percent resided in the urban area as presented in Table 13.  This percentage of urban population is higher than the 18.65 percent  in 1990 and 16.50 percent in 1980. There is an evident upward trend of urban population in the last 15 years although at a very minimal rate of increase. It may be due to the presence of infrastructure and basic service facilities in the rural areas, the lack of which is usually the reason for people to go to the urban center. Accessibility of the rural areas could also be the reason why many people still opt to live there and commute to and from work daily.

            Among the barangays with bigger population are Ilaya-Ivisan (rural), Poblacion Norte (urban) and Basiao (rural) with a population of 2,305, 2292 and 2,273 respectively. Barangay with least population is Agustin Navarra with only 734 people.

Mother Tongue

            Majority  of Ivisanons speak Ilonggo/Hiligaynon with a total of 97.94 percent speaking the dialect as can be gleaned in Table 14. This is due to the proximity of Ivisan to Roxas City, the provincial capital which is an Ilonggo/Hiligaynon  speaking area.  Another dialect spoken most by the population is Tagalog which counts at 0.72 percent, a language being taught in school and most of the population had been to Manila for job opportunities. Other dialects spoken by the population are Aklanon, Cebuano, Bicolano, Masbateño, Negrito, Chavacano, Ilocano, Waray and a combination of other dialects.

Religion of the Population

            Majority of the religious affiliation of the population is Roman Catholic which comprises 97.36 percent as presented in Table 15. Other religions of the population are Aglipayan, Iglesia ni Kristo, Jehovah’s Witness, PBMA (Philippine Benevolent Missionary Association), Seventh Day Adventist, Born Again Christians, Assembly of God, Protestant, and other religious groups which accounted for a total of 2.64 percent.

Labor Force

            Based on Table 16 as obtained from the 1990 census  there are a total of 12,393 population that are 15 years and over. Of this population, 7,847 or 63.32 percent are in the labor force or economically active  and 4,546 or 36.68 percent are not economically active. Of the economically active population, 5,146 or 65.58 percent are male and 2,701 or 34.42 percent are female. Among the economically active male population 4,991 or percent are employed and only 155 are unemployed.

Of the economically active female population 2,516 are employed and 185 are unemployed. Female population in the labor force is further broken down into 95.67 percent employed and 4.33 percent unemployed. 

It could be noted that there are more male that are economically active and employed than their female counterpart. Again, this could be attributed to the Filipino culture where women are usually left behind to take care of family instead of finding gainful employment outside of the home.

            By the projected population of 25,431 in the year 2006,  14,946 or 55.5 percent will contribute to the labor force.

Literacy Rate

            Literacy rate of the municipality in 1980 is 75.09 percent. This figure dramatically increased to 92.08 percent in 1990 as presented in Table 17 and Figure 17. This dramatic increase could be attributed to the efforts of the Department of Education,  Culture and Sports (DECS) through the program and projects implemented which aimed at upgrading teaching competencies and physical facilities of the schools or learning centers. The repeal of Continuous Progression Program and the on going Non-Formal Education Program which offers functional literacy skills to adults has also contributed to this high literacy rate.

Highest Grade Completed of Population

            Data obtained from the 1990 NSO record (Table 18) shows that 10,372 or 60.26 percent of the population 7 years old and over have acquired elementary education. This is  followed by those that have acquired secondary education with a total of 3,735 or 21.20 percent.  Population with no grade completed reached 1,036 or 6.02 percent and those that have reach college but were not able to get a degree totals to 913 or 5.30 percent. There are 637 or 3.70 percent that are college degree holder. Only 410 or 2.31 percent were able to have post secondary/vocational courses and those that were able to finish pre-school reached 67 or 0.39 percent of the population 7 years old and over.  Graphical presentation of the data could be seen in Figure 18.

Marital Status of the Population

Statistics on the marital status of the population 18 years and above obtained from the municipal survey conducted in 1995 is presented in Table 19. A total of 10,880 or 25.99 percent belonging to the age group are single, 7,477 or 63.15 percent are married, 572 or 4.83 percent are widow, 80 or .067 percent are separated  and about 5.35 percent did not state their marital status. 

Table 20 shows the marriageable age of the population. Of the 98 marriages that took place in 1995, 114 of either spouse or both spouses are within the age bracket of 18-27. Most women marry at 18-22 followed by 23-27 age bracket while most men marry at older age bracket of 23-27 and 28-32. The age bracket with the least number of marriages for both sexes is 38 and over.  The 18-27 age bracket for women happen to the peak of reproductive years which could probably be a contributing to the high birth rate  of 23.40 percent.
