The IUSSP International Population Conference is a major international event drawing over 2,000 scientists, policy makers and practitioners in the global population community to meet and address issues of common concern. The Conference takes place once every four years, providing a unique forum for population experts to take stock of recent research on population trends and issues and to debate possible actions and policy responses to the challenges posed by population phenomena. The Conference will include invited plenary debates and panel discussions on population and sustainable development issues as well as over 240 scientific sessions featuring the results of recent research from around the globe. Sessions will cover a wide range of topics including international migration, sexual and reproductive health, poverty and inequality, population and environment interactions, the consequences of population ageing and issues related to children and youth, education, the labour force, and gender and human rights. There will also be a set of sessions on Population and Policy Challenges in Africa. Attention to advances in methods and data measuring population phenomena and evaluating progress towards health and development goals such as the SDGs will be a key concern cutting across all sessions. In addition, there will be exhibits, side meetings and training sessions. The Conference is open to all members of the population community and draws in experts working in research, teaching, governmental and non-governmental organizations, as well as the private sector including publishing companies and the media. Institutions working in the population field are encouraged to organise exhibits, side meetings, and training workshops or become an institutional sponsor. Further information on these opportunities will be posted on this website.
