Children's spaces are widening culturally and socially. Socially, childrens spaces are more often multilocal. Culturally, they are enlarged through mobility in the globalized and virtual spaces in the media-saturated world. Children's times are also less confined by strict borderlines. The more flexible and individualized use of time in the world of work impacts on children's lives in families, day care, and school. The chapters of this volume each present particular temporal and spatial aspects of social change in childhood. The book is directed toward considering the impact of such change on children's welfare.
