This study examined the characteristics, past and present, of different groups of unpaid caregivers in England and Wales in 2001. As not all people with care needs can be looked after at home, it also examined characteristics of older people who had moved into institutional care, and those who had moved in with other relatives. The research, by a team from the Centre for Population Studies, London School of Hygiene and Tropical Medicine, used data from the Office for National Statistics Longitudinal Study, including individual-level census information.
