Living alone is increasingly common these days. Through the prism of multimedia equipment and its use, this article explores the way in which single people occupy space in their home and the time that they spend there. Limited to the 18-55 age-group, and by comparing singles to couples, the quantitative approach on which it is based shows that their daily lives are less strongly marked by differences of identity (gender or age) than by common features. People who live alone tend to have less variety of equipment. Yet, because they do not have to negotiate the use of their domestic territory and because they are alone, they are enthusiastic users of various multimedia and synchronous screen-based activities, both for recreational purposes and to maintain near-continuous contact with people to whom they are close (or not), living elsewhere.
