National Data Archive: An Online Microdata Library

The National Data Archive has been disseminating microdata from surveys and censuses primarily under the Ministry of Statistics and Programme Implementation (MoSPI), Government of India. The archive is powered by the National Data Archive (NADA, ver. 4.3) software with DDI Metadata standard. It serves as a portal for researchers to browse, search, and download relevant datasets freely; even with related documentation (viz. survey methodology, sampling procedures, questionnaires, instructions, survey reports, classifications, code directories, etc). A few data files require the user to apply for approval to access with no charge. Currently, the archive holds more than 144 datasets of the National Sample Surveys (NSS), Annual Survey of Industries (ASI), and the Economic Census as available with the Ministry. However, efforts are being made to include metadata of surveys conducted by the State Governments and other government agencies.

国家数据档案馆主要在印度统计与计划实施部（MoSPI）的指导下，传播来自调查和人口普查的微观数据。该档案馆采用国家数据档案馆（NADA，版本4.3）软件，并遵循DDI元数据标准。它作为研究人员的门户，允许用户自由浏览、搜索和下载相关数据集；甚至包括相关的文档（例如调查方法、抽样程序、问卷、指示、调查报告、分类、代码目录等）。部分数据文件要求用户申请批准后方可无费访问。目前，该档案馆收藏了超过144个国家级样本调查（NSS）、年度产业调查（ASI）和经济普查的数据集，这些数据集由印度政府部 门提供。然而，档案馆正致力于纳入由州政府及其他政府部门开展的调查的元数据。
