Methodology
This dataset is sourced from the OECD through its official SDMX data service.
Rankdat does not alter or model the underlying values — we only clean formats, standardize country names, and reshape the data for visualization.
OECD compiles these indicators from a mix of sources including national statistical offices, international household surveys (such as Gallup World Poll, EU-SILC, ISSP), and harmonised administrative datasets.
Each indicator follows the definitions and structure specified in the OECD’s Data Structure Definition (DSD) for this dataflow.
Because indicators originate from different countries and surveys, collection years, sampling methods, and questionnaire wording may vary. OECD applies harmonisation rules to improve comparability, but differences in national methodology may still affect cross-country comparisons.
Full definitions, data collection notes, and quality documentation are available through the OECD metadata portal linked in the Sources section.
