According to the 2020 Census of Population and Housing, Barangay Talisay had a population of 1,177 residents — the constituency that Samuel serves as Punong Barangay. Masbate is classified as a 1st by the Bureau of Local Government Finance.

Elected through the Barangay and Sangguniang Kabataan Elections, Samuel Mahinay Osa is serving the current four-year term established under Republic Act No. 12232, which extended the barangay official's term from three years to four. The next BSKE will be held on Monday, November 2, 2026, following COMELEC Resolution No. 11191.

A Philippine barangay's Sangguniang Barangay is composed of one Punong Barangay, seven Sangguniang Barangay Members (kagawads), a Sangguniang Kabataan (SK) Chairperson representing the youth sector, a Barangay Secretary, and a Barangay Treasurer. Together, these officials administer the smallest unit of Philippine local government and deliver frontline services — from barangay clearance issuance to peace and order, from public health assistance to the barangay's share of the Internal Revenue Allotment.
