This open access book focuses on family diversity and investigates the relationship between law and behaviours by focusing on LGBT people in four countries in Europe with different legal systems (France, Iceland, Italy and Spain).   It examines, from a legal point of view and a social perspective, what is at stake in the changing life of LGBT people and their perception of these changes.  The book investigates, from a legal point of view and from a social perspective, what is at stake in the life of homosexuals in the field of family formation, parenting and parentality, what it brings to everyday life, the support of the law, and what its absence implies.  Demographic analyses enrich the aspects in dealing with registration and parenting and statistical analyses of same sex partnerships and same-sex marriages show frequencies of registration together with a focus on parenting linked to the partnership status.  As such this book is an interesting read to demographers, sociologists, behavioural scientists, and all those working in law and the field. weiterlesen
