Children and young people's participation is an ever-growing demand. Thirty years on from the UN Convention on the Rights of the Child's adoption, however, fundamental challenges continue for participation that are widely recognised cross-nationally but remain stubbornly consistent. As a way in to considering the children and young people's participation literature more generally, all articles referring to participation in their titles were identified from The International Journal of Children's Rights. These 56 articles were analysed to identify trends, challenges and opportunities. The analysis found: a remarkably consistent narrative on participation over the 30 years; limitations on domains considered, geography and conceptual clarity; and far more written about challenges than solutions. Drawing on these findings and considering the participation literature more generally, the article recommends that the field expands its geographic and intellectual boundaries, uses powerful concepts like agency, competency and autonomy with greater precision, and explores fresh ideas like child protoganism, activism and children as human rights defenders.
