The number of persons in the labor force, or those who are either employed or unemployed, was estimated at 36.4 million out of the estimated 57.4 million population 15 years old and over in January 2008. These numbers translate into a labor force participation rate (LFPR) of 63.4 percent compared to last year's figure of 64.8 percent. The LFPR was highest in Northern Mindanao at 69.5 percent, while lowest in Autonomous Region in Muslim Mindanao (ARMM) at 57.1 percent.
