There is a now consensus that addressing child poverty is important to breaking long-term social and economic drivers of poverty, and to reflecting the human rights agenda. Indeed, the commitment is enshrined in the Sustainable Development Goals (SDGs). This consensus is recent and not universal. Only three years ago I was discussing the issue with governmental officials who said, ‘children can’t be poor because they don’t work’. So, it is important not to be complacent and to work on improving evidential and advocacy-based approaches, as discussed later in this Dimensions issue.
