We're now entering the last plenary session which is recapping the various tracks.

The first overview is from the Counting what Counts strand. That track started with discussions of disaggregation. Looked at various techniques, like surveys, through to using big data. Risks discussed included challenges of too much disaggregation and therefore being overwhelmed in data and being able to re identify individuals. The strand also discussed perceptions data and that we need not just to tell people that their lives are getting better but also to ask them how they're thinking about it. Last session highlighted the importance of data use.

For second track on big data there were four key points. A) Lots of excitement about opportunities in big data. B) this area has really matured over the last six to twelve months. We're past simplistic arguments and controversies. It's on to more nuanced discussions of the politics of big data. C) social media data use presents big opportunities but also the raises issues on the limits of privacy. The arguments is that there is no such thing as anonymised data and we need to have a discussion as a society on the balance between liberty and progress. D) regional discussions showed different approaches. 'African' view of big data used words like 'neo-colonialism' and that it's an extractive industry. But there was also lots of talk about linking across regions and build capacity to engage with this sort of data.

And the third track focused on opportunities of national statistical organisations in this data revolution. Focused on capacity, literacy and engagement.
