World War II caused the deaths of 60 to 75 million people.
Notes on verification
Multiple independent sources (Wikipedia, History.com, EBSCO) corroborate a range that overlaps with the claimed 60-75 million figure, though exact totals vary across sources due to inherent record-keeping uncertainty. [tier=bronze indep_score=0.3 clusters=2 claim_tier=everyday]
