This postscript highlights the key features of this book, especially its combination of different approaches using legal, demographic and sociological analysis tools, and the comparative perspective that is present throughout. The approach is particularly useful, because the three disciplines that structure the book do not view same-sex families in the same way. Another strand in the book is a more direct reflection on marriage. While marriage has been the symbol of the recognition of sexual minorities in recent years, the book shows that it cannot fully embody it, and invites us to think “beyond marriage”. The last part of this postscript will suggest research themes that could usefully be investigated, provided that suitable tools are used – particularly the tools of quantitative sociology, since the social and scientific visibility of same-sex parenthood does not always mean statistical visibility.
