A global health and environment dataset integrating seven international sources 1990-2023

GloHEAD (Global Health and Environment Aggregated Dataset) is a harmonized database integrating seven major international data sources for environmental epidemiology research.

Data sources include:
- Global Burden of Disease Study 2023 (disease burden estimates)
- GBD Summary Exposure Values (89 risk factors)
- ERA5 climate reanalysis (temperature, precipitation)
- World Bank Development Indicators (socioeconomic data)
- WHO Global Health Observatory (environmental health)
- Satellite-derived PM2.5 concentrations

- Temporal coverage: 1990-2023
- Spatial coverage: 204 GBD countries and territories
- Over 7.2 million records across 8 core tables
- Standardized country names enabling cross-source joins
- SQLite format with comprehensive documentation

The dataset removes technical barriers to multi-source data harmonization, enabling hypothesis generation and trend analysis for global health research. Full processing code and validation scripts are included.
