Given a sponsor-authorized release of a commissioned survey item, SWS is disclosing pertinent survey results and technical details for the benefit of the public.
The Stratbase-SWS April 11-15, 2025 National Survey contained a question sponsored by Stratbase Consultancy on voter preferences for senators. The survey used the list of 66 names based on the revised ballot face template released by the Commission on Elections (COMELEC).

The Stratbase-SWS April 2025 National Survey was conducted April 11-15, 2025, using face-to-face interviews of 1,800 registered voters (18 years old and above) nationwide: 300 in Metro Manila, 900 in Balance Luzon (or Luzon outside Metro Manila), 300 in the Visayas, and 300 in Mindanao. Face-to-face is the standard interviewing method for Social Weather Stations; the only exceptions were early in the pandemic when movement restrictions made face-to-face impossible and mobile phone interviews were conducted. Normal face-to-face field operations resumed in November 2020. The sampling error margins are ±2.31% for national percentages, ±3.27% for Balance Luzon, and ±5.66% each for Metro Manila, the Visayas and Mindanao.
The area estimates were weighted by the COMELEC 2025 Project of Precincts data for validated voters to obtain the national estimates.
