Data Accompanying "International Trade and Air-Quality-Related Mortality"

**Data Description:** This dataset provides country- and sector-level estimates of air-pollution–related health impacts, economic externalities, and associated spatial concentration patterns derived from multi-regional input–output (MRIO) modeling and atmospheric simulations (GTAP and EORA frameworks). Files include production- and consumption-based mortality matrices, gridded PM₂.₅ concentration maps, trade-linked net export metrics, externalities, uncertainty analyses, and cross-model correlation summaries used to generate the figures and tables in the manuscript. **Citation Requirement:** If you use this dataset in your research, presentations, or derivative works, please cite both the associated paper and the dataset: Wang, S., Thakrar, S., Johnson, J. et al.
