be elected within the province, and the number within each SP district, varies depending on several factors, including the province's income class and the population count within districts. Ex officio members in the Sanggunian include: the president of the provincial chapter of the Liga ng mga Barangay the president of the provincial federation of Youth Councils (Sangguniang Kabataan) the president of the provincial federation of the Philippine Councilors League (Sangguniang Panlungsod and Sangguniang Bayan members from component cities and municipalities) Reserved seats in the Sanggunian include: the Indigenous People Mandatory Representation (IPMR) is pursuant to the Republic Act 8371, or the Indigenous Peoples' Rights Act of 1997, which calls for the mandatory representation of IPs which is formally certified by the concerned National Commission on Indigenous People (NCIP) regional director, upon recommendation of the provincial or community service center head and shall serve for a period of three years from the date of assumption to office and can be re-endorsed for another term as long as he or she would not serve for more than three consecutive terms. The Local Government Code of 1991 also provides for the election of 3 "sectoral representatives," which are supposed to come from: women's sector agricultural or industrial sector other sectors, including the disabled, the urban poor, or indigenous cultural communities Although several attempts have been made in the past to provide for the election of these sectoral representatives, the lack of a more concrete enabling law upon which the manner of election of these sectoral representatives can be legally based continues to prevent this feature of local governments from being fully realized. Allocation and apportionment of regularly elected members The number of regular Sanggunian members is based on the income of the province as classified by the Department of Finance. The Commission on Elections issues resolutions allocating the number of regular members of the Sanggunian a province may elect should a province's income classification change. First-class and second-class provinces are entitled to 10 regularly elected members, 8 for third- and fourth-class provinces and 6 for fifth- and sixth-class provinces. Exceptions to the rule are provinces which are divided into more than five congressional districts. Each Sangguniang Panlalawigan district in the provinces of Batangas, Cavite, Cebu, Negros Occidental and Pangasinan elect two members to the Sanggunian, resulting in a total number of 16 regularly elected SP members in Cavite, 14 in Cebu, and 12
