Approximately 30% of caregivers die before the loved ones they care for.
"And there is this also this percentage that 30% of caregivers do die before their loved ones." (said at 0:56:16)
No published record matching the claim that approximately 30% of caregivers die before the loved ones they care for was located; this does not prove the claim false. While landmark observational studies (such as the Caregiver Health Effects Study) have evaluated mortality risks associated with caregiver strain, published epidemiological data verifying a specific 30% pre-deceased rate among informal caregivers were not identified.
