This study describes and analyses the types of informal care provided in Sweden and whether it is possible to distinguish different types of carers. Data were collected in a Swedish county in 2000, by means of telephone interviews. The net sample consisted of 2,697 individuals 18–84 years old, and the response rate was 61 per cent. The results showed that there were large differences in the numbers of male and female carers when the data were divided into a typology of care categories based on different caring tasks. Women were much more likely than men to be involved at the ‘heavy end’ of caring, i.e. providing personal care in combination with a variety of other caring tasks. Men were more likely to provide some kind of practical help for a mother or a neighbour/friend. Even though the Swedish welfare state has been described as universal and characterised by an extensive system of benefits and services intended to cover the entire population, the results here indicate that informal care plays an important role and that the gender role patterns are similar to those observed in other types of welfare state. When discussing support systems it is important for social policy to develop programmes that take into account the support needs of both caregivers and care recipients, and not to see their needs in isolation from the social care system as a whole
