Population to double in 20 years

Lanao del Sur, one of the four provinces of Autonomous Region in Muslim Mindanao (ARMM) reported a total population of 669,072 persons in the 2000 Census of Population and Housing. This implied an increase of 97,268 persons over the 1995 census figure.

This resulted to an average growth rate of 3.42 percent, up by 1.18 percentage points from the 1990 to 1995 period. If the current growth rate continues, the population of Lanao del Sur is expected to double in 20 years.

The number of households increased to 97,104 as compared to 91,683 households in 1995. The average household size recorded was 6.89 persons, higher than the 1995 figure of 6.23 percent and the national average of five persons.

Lanao del Sur ranked second in ARMM

Lanao del Sur ranked second in terms of population size among the four provinces (Maguindanao, Lanao del Sur, Sulu and Tawi-tawi) in ARMM. The province shared more than one-fourth (27.74 percent) to the 2.4 million population of the region. At the national level, Lanao del Sur shared 0.87 percent to the total population of 76.5 million.

Sultan Dumalondong, the newest municipality in Lanao del Sur

Females made up the bulk of the younger age group 0 to 35 years, while males dominated the older age group 40 years and over.

Females outnumbered their male counterparts with a sex ratio of 94.27 males for every 100 females. This was due to the large population in the younger age group dominated by females.

Dependency ratio almost unchanged at 85.18

In 2000, the overall dependency ratio was 85.18. This was almost the same as the 1995 ratio of 85.55. This meant that for every 100 persons aged 15-64 years, there were about 85 dependents (82 persons aged 0-14 years - young dependents and three persons aged 65 years and over - old dependents).
