Polisi has led on reactive, evidence-based projects, as well as generating new evidence and thinking on a broad range of subjects that impact on population health and well-being in Wales. With a focus on the domestic policy context, Polisi has undertaken work in a range of subjects, including the potential impacts of Brexit, the intersection of health and the wider economy, the case for investment in housing improvements and how futures thinking can be incorporated into public health policy planning.
