This briefing note summarises a review of literature and policies on youth demographics and implications from our scenario modelling of the short, medium and long-term projections of the youth population in Tanzania, and their demand for services. From the literature review and participatory workshops on the demographic dividend in the four East Africa Community countries (EAC), we have identified four major domains for youth development: health including access to sexual and reproductive health services; education and skills development - including information technology and communication; employment; and migration and urbanisation. Gender is a cross-cutting issue for youth development. This briefing note focuses on these domains, while acknowledging that there are other important domains in youth development that should be addressed. It also draws from the country’s demographic dividend report (2017) for which the African Institute for Development Policy (AFIDEP) provided technical leadership.
