The Vulnerability & One Parent Family Network (VOPFN) is the first to create a shared forum for historians, archivists and Non-Governmental Organizations (NGOs) working on one-parent families in the OECD countries of England, Scotland, Ireland, Australia and New Zealand. Through participatory research it draws upon the collective insights and expertise of this group to explore the similarities and differences between these NGOs and the role of history in contemporary and future one-parent family policy and experience.
