Officially local government in the Philippines, often called local government units or LGUs, are divided into three levels – provinces and independent cities; component cities and municipalities; and barangays. In one area, above provinces and independent cities, is an autonomous region, the Autonomous Region of Muslim Mindanao. Below barangays in some cities and municipalities are sitios and puroks. All of these, with the except of sitios and puroks, elect their own executives and legislatures. Sitios and puroks are often led by elected barangay councilors.
