Abstract: Empirical analysis needs data. Nowadays, official tabular data are increasingly considered as a public good that people should have access to. However, microdata often remain inaccessible to the research communities, due to technical, financial, legal, even political obstacles.Non accessibility to microdata forced users to conduct their own surveys and resulted in duplicated activities and great waste of money and time, at the same time, the existing datasets remained under-exploited, which in turn limited the return of data collection investment.This paper makes comparison between China and other countries on disseminating microdata; summaries the utilities and the risks of microdata dissemination, and argues that the most issue is the contradiction between the need of microdata and the disclosure risk; introduces current approaches of statistical disclosure limitation (SDL); tries to give some suggestions on China’s microdata dissemination.
