Survey Methodology
The technical details of the 2025 OECD Trust Survey Data collection follow the methodology of the 2021 and 2023 data collection, as described in 2023 OECD Trust Survey Technical Documentation and 2021 OECD Trust Survey. Fieldwork periods and sample sizes for the 2025 Trust Survey are detailed in Table A.3 of OECD Survey on Drivers of Trust in Public Institutions 2026 Results: Navigating Rising Expectations and New Horizons; and the 2025 questionnaire can be accessed here.
Accessing Microdata
OECD Trust Survey Microdata are available for non-commercial academic and policy research. To request access to the OECD Trust Survey Public Use Microdata for research, please fill out either the general or graduate student terms of use and submit it to govtrustinfo@oecd.org. The OECD Trust Survey team will review your request based on whether your proposed research question can reasonably be addressed using Trust Survey data and requires microdata rather than the indicators published through the Stat.Links associated with each figure in the respective Trust Survey report (2022, 2024, 2026 and the 2025 OECD Trust Survey in Latin America and the Caribbean).
