Civilians accounted for 80 percent of all bombing casualties in Laos, and the war killed 10 percent of the country's population.
Notes on verification
The 10% population death toll is well corroborated by multiple independent sources (History.com, academic journal, CFR summary of Kurlantzick's book). The 80% civilian casualty figure is consistent with reporting on the US bombing campaign but lacks a fully independent secondary source confirming that exact statistic.
