| Demographic Characteristics of Sabtang |
| The Barangays - Nearly one in two Isabtangs or 48% of the population live in the town proper that comprises the barangays of Malakdang and Sinakan. Nakanmuan with a population of 126 is the smallest barangay in all of Batanes. Imnajbu, Batanes with a population of 130 was the second lowest. Median Age - A way to measure the aging of a population is the median age, the age at which half of the population is younger and half is older. In 1995, the median age in Sabtang |
| was 21.8 years. Because of a higher life expectancy, the median age of Sabtang women was greater than that of Sabtang men by 2.6 years, 23.3 years and 20.7 years, respectively. Age Structure - While the median age shows the aging of the population, a more detailed picture may be obtained by looking at age groups. A useful breakdown distinguishes between persons aged under 15 (children), those 15-64 (working age population) and those 65 and over (elderly). |
| In 1995, children accounted for 36.5% of the total population of Sabtang compared to 37.8 for Batanes. Working age population accounted for 54.5% while the proportion of persons aged 65 and over was 9%. A greater proportion of women than of men were aged 65 and over, 11.3% and 6.8%, respectively. The major difference between the figures for men and women in this age group was primarily because of higher male mortality. Dependency Ratio - The various dependency ratios (for children, for the aged and the total ratio) also serve as useful indicators |
