The Global Burden of Disease Study 2021 (GBD 2021), coordinated by the Institute for Health Metrics and Evaluation (IHME), estimated the burden of diseases, injuries, and risk factors for 204 countries and territories and selected subnational locations.

This dataset includes estimates of the burden associated with lower respiratory infection (LRI) and LRI pathogens for Global Burden of Disease Study (GBD) countries in 1990, 2019, 2020, and 2021. Input data for the overall LRI mortality model came from the cause of death (CoD) database. The CoD database contains several types of data sources, five of which are used in estimation of LRI: vital registration (VR), verbal autopsy (VA), sample vital registration (VR-S), surveillance, and minimally invasive tissue sample (MITS) diagnoses.
