A sex ratio of 102 males per 100 females was computed in 2007. The sex ratio in 2000 was 100 males for every 100 females, meaning the number of males equals that of females.

Males outnumbered females in age brackets 0 to 49 years while females outnumbered males in age brackets 50 years and over.

Median age increased to 25 years

The median age of the household population of the province increased from 23 years in 2000 to 25 years in 2007. The median age of 25 in 2007 means that half of the household population for that year was below 25 years old.


Age groups 0 to 4 years (10.4 percent), 5 to 9 years (10.5 percent), and 10 to 14 years (10.5 percent) comprised almost one-third of the total household population.

The overall dependency ratio in 2007 was 63 dependents (51 young and 12 old dependents) per 100 persons in the working-age population. This is slightly lower than the ratio recorded in 2000, at 64 dependents per 100 persons in the working-age population.

Married persons comprised nearly half of household population 10 years old and over

Eight in every 10 (79.1 percent) of the household population were 10 years old and over. Of this age group, 49.0 percent were married while 41.8 percent were never married. Those who were widowed, or divorced/separated, or who had common-law/live-in marital arrangement, or had unknown marital status made up less than 10.0 percent.

Among the never married persons in 2007, there were more males (54.9 percent) than females (45.1 percent). Females outnumbered males in the rest of the categories for marital status.

In 2007, there were 131,204 occupied housing units in Ilocos Sur. This number is 13.5 percent higher than the occupied housing units of 115,586 recorded in 2000. This translated to a ratio of 102 households per 100 occupied housing units in 2007, lower than the ratio of 103 households per 100 occupied housing units in 2000. A ratio of 4.8 persons per occupied housing unit was recorded in 2007, down from a ratio of 5.1 persons per occupied housing unit in 2000.
