Demand Dynamics & Structure

The signal counts elsewhere in this section are a snapshot. This page asks what is moving: which themes have grown or shrunk as a share of newer evidence, which gap types travel together and therefore need bundled responses, and how much weight the evidence base can bear given how recent, traceable and independently corroborated it is.
