Denise will draw on her experience of working as a statistician in the UN system to discuss the problems of gathering harmonised data from across countries with very different levels of statistical expertise and resources. She will discuss how statistics can help us to monitor the progress towards internationally agreed goals and how statistics can help countries learn from one another. Denise has a particular interest in the topic of trust in official data and so she will talk about some ways in which the level of trust might be improved.
