Population of Ilocos Sur increased at the rate of 1.03 percent annually

Based on the 2010 Census of Population and Housing (CPH), the province of Ilocos Sur posted a total population of 658,587 persons as of May 1, 2010.  This is larger by 64,381 persons compared to its total population of 594,206 persons counted in the 2000 CPH.  The increase in the population count from 2000 to 2010 translated to an average annual population growth rate (PGR) of 1.03 percent.  This is lower than the 1.34 percent annual PGR of the province between the census years 1990 and 2000.

If the average annual PGR recorded at 1.03 percent during the period 2000 to 2010 continues, the population of Ilocos Sur would double in 68 years.  

Fifty years ago, the population of Ilocos Sur was only 338,058 persons.  This population size is less than half of the population of the province in the 2010 CPH.

 

City of Candon was the most populous

Among the two cities and 32 municipalities comprising the province of Ilocos Sur, the City of Candon was the most populous with a population size making up 8.8 percent of the total provincial population.  The City of Vigan, the provincial capital, was second with 7.6 percent share, followed by the municipalities of Narvacan (6.5 percent), Tagudin and Santa Cruz (5.8 percent each), Cabugao (5.4 percent), and Bantay (5.2 percent). The rest of the municipalities contributed less than 5.0 percent each.

The least populated area was the municipality of Sigay with 0.4 percent share to the total population of the province. It was also the least populated area in 2000.

 

Sex ratio was 101 males per 100 females

Of the 657,902 household population in 2010, males accounted for 50.3 percent while females comprised 49.7 percent.  These figures resulted in a sex ratio of 101 males for every 100 females, which is similar to the sex ratio recorded in 2000 (100 males per 100 females).

Median age increased to 26.6 years

In 2010, the median age of the population of the province was 26.6 years, which means that half of the population was younger than 26.6 years. This is higher than the median age of 24.0 years that was recorded in 2000.

Moreover, almost three in every 10 persons (29.1 percent) were under 15 years old.  Children aged 5 to 9 years (9.9 percent) comprised the largest age group, followed closely by those in the age groups 0 to 4 years (9.7 percent) and 10 to 14 years (9.5 percent).  Males outnumbered females in the age groups 0 to 49 years. On the other hand, there were more females than males in the older age groups (50 years and over).

 

Nearly two thirds of the population were of voting age

The voting-age population (18 years and over) accounted for 65.0 percent of the household population of the province in 2010, up from 61.5 percent in 2000.  There were more females (50.6 percent) than males (49.4 percent) among the voting-age population.

Dependency ratio decreased to 57 dependents per 100 persons in the working age group

In 2010, the young dependents (0 to 14 years) comprised 29.1 percent of the household population while the old dependents (65 years and over) posted a share of 7.2 percent. The working-age population (15 to 64 years) accounted for the remaining 63.7 percent.          

The overall dependency ratio was 57, which indicates that for every 100 working-age population, there were about 57 dependents (46 young dependents and 11 old dependents). This ratio is lower than the dependency ratio in 2000, which was recorded at 64 dependents per 100 working-age population (53 young dependents and 11 old dependents).

There were more males than females among the never-married persons

Of the household population 10 years old and over, 49.3 percent were married while 40.8 percent were never married. The rest of the population were categorized as follows: widowed (5.8 percent), in common-law/live-in marital arrangement (3.1 percent), and divorced/separated (0.9 percent).

Among the never-married persons, 54.5 percent were males while 45.5 percent were females.  For the rest of the categories for marital status, the females outnumbered the males.

Moreover, of the total 16,748 persons aged five years and over with at least one type of functional difficulty, 52.3 percent reported difficulty in seeing, even if wearing eyeglasses.  There were 34.3 percent who had difficulty in walking or climbing steps; 29.5 percent had difficulty in hearing, even if using a hearing aid; 18.8 percent had difficulty in remembering or concentrating; 15.5 percent had difficulty in communicating; and 15.3 percent had difficulty in self-caring (bathing or dressing).
