Methodology & Data Sources

Our approach

Pendex uses public datasets and publicly available health information covering the countries in our dataset. We bring these sources together in one place and build tools around them to help people better understand how population-level statistics relate to their own situation.

How we build the tools

  1. Collect: identify public datasets and published sources that provide relevant country-level measurements or health indicators.
  2. Consolidate: normalise the available country records into a consistent internal structure, while preserving the source attributed to each figure.
  3. Explain: present national averages alongside global comparisons, definitions, units, and relevant context rather than treating a single number as a personal diagnosis.
  4. Support: provide links to public health agencies, specialist organisations, and other sources of information so visitors can find appropriate next steps when they need more than a comparison tool can provide.

Data sources

Each country page cites the source used for its measurement under “Data Sources & Methodology”. Depending on the country, the public sources represented in the current dataset include the World Health Organization, WorldData, and World Population Review, alongside national government health websites and other public health organisations.

Referrals and health information

Where appropriate, country pages include referrals to government health agencies, public health organisations, mental health services, and further reading. These links are intended to help visitors locate reputable information and support. They are not endorsements, diagnoses, or substitute medical advice, and availability may vary by country.

Limitations

Country averages are population-level statistics, not individual benchmarks. Public datasets can differ in sample size, measurement technique, definitions, coverage, and year of collection. Combining sources improves access and comparability but does not eliminate those differences. We treat figures as approximate and recommend against drawing strong personal conclusions from a single national average.
