Globally, the number of cases of elder abuse is projected to double, from 542 million in 1995 to about 1.2 billion in 2025. Many countries have rapidly ageing populations whose needs may not be fully met due to resource constraints. Abuse of the elderly presents a public health problem. The WHO is working with its partners to build evidence on the types of elder abuse in different settings and develop guidance for Member States and relevant sectors to prevent elder abuse and strengthen their responses to it.
