Data Source: The Institute for Health Metrics and Evaluation's 2021 Global Burden of Disease (GBD) study.
The cumulative population blood lead level (alternately 'Lead Burden Index'), combines average lead blood levels with population size. It can act as an indicator of gross intellectual impairment or cardiovascular disease. This metric can be used to estimate the burden of lead in different countries or regions, and between different source(s) of lead when known. The tool is instructive for donors, governments and United Nations agencies when comparing a range of interventions for viability or cost-effectiveness.
