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.

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.
