Recognizing that effective financing strategies cannot be achieved without comprehensive, comparable and detailed data, this chapter looks at current initiatives to improve sectoral development finance information. After a short section looking at the evolution of the data landscape, the second section provides an overview of the initiatives currently underway to provide an increasingly comprehensive and qualitative picture of sectoral development finance data in response to the Addis Ababa Action Agenda, with the measurement of an ever larger set of flows, providers and modalities. The third section then provides insights into the critical articulation between sectors traditionally used for data reporting and the Sustainable Development Goals (SDGs). The fourth section builds on the dual recognition that the financing picture of sectors cannot improve without the participation of all actors and the standardization of development finance information across providers. This section, therefore, unpacks the potential for sectoral analyses of the new statistical framework of total official support for sustainable development, designed to track external resources in support of sustainable development by providers of development co-operation.
