 In support of the Sustainable Development Goals, the United Nations has called for a data revolution. Vietnam, together with UNU Wider and its partners, have established data sets charting the country's rapid development. This series shares some of the lessons learned. This is the first time we have hundred data for the rural households. We have another survey and have the even Vietnam Living Standard survey, but data from the vast survey is focusing on the economic approaches. So that data is very important for policy formulation. My recommendation are several. The first one is that you have to build the network, the research network, because such kind of issues cannot be involved by one single research institution. The second thing is that you have to make sure that the data is collected, have the final data and also reliable, so that you can do further analysis, especially when you do some kind of econometrics analysis. The third one is that you have to make sure that the data can translate into some policy results, because people don't want to receive you every two years without any impact on their life. So we make sure that the data collected can be maximized, used by policy makers. Last but not the least, you have to make sure that all the research evidence can be translated into the policy amendments and developments.
