Policies to promote informal social care have particular importance for elderly people, since a substantial minority of them are in receipt of informal care from kin, neighbours and friends, and the majority of those living in their own homes who receive informal care are themselves elderly. Yet informal care has not had the attention it deserves, compared to care provided by statutory, commercial or organised voluntary effort. This paper focuses on neighbourhood care, drawing on the results of a five-year research programme. Three types of neighbourhood care are examined: voluntary action for neighbourhood involvement, voluntary action for informal care, and voluntary action for neighbourhood care. Neighbourhood involvement is increasingly a political matter, with local organisation tied to specific local issues. Informal care has little directly to do with local involvement. Nine-tenths of such care is provided by kin, though there is scope for greater local action. Voluntary action for neighbourhood care is encouraged particularly by pressure-group activism, self-help organisations and support for carers. Effective informal care requires a higher degree of competence and the establishment of contexts for reciprocity. Policies in this area need to provide modest financial resources, greater information exchange and support for carers.
