Background: Caregivers play an indispensable role in society. In 2017, 41 million family caregivers in the United States provided approximately 34 billion hours of care to their aging parents, spouses, partners and friends. The estimated economic value of their unpaid contributions amounted to $470 billion. Despite their invaluable contributions, caregivers often operate in a reality of inadequate social support. Little is known about the factors linked to the societal perceptions of caregivers, and our study seeks to contribute by filling this gap.
