The Population and Housing Census is one of three national statistical censuses as stipulated in the Statistics Law. The Census sought to collect basic population and housing information across the entire Socialist Republic of viet Nam to serve national socio-economic development policies and to monitor the implementation of Sustainable Development Goals per the Government of Viet Nam's commitment. The 2019 Population and Housing Census was implemented in the context of a vigorous fourth technological revolution, and applied information technology in all stages of the Census for the first tim. Three types of information collection were used synchronously: an online survey form, a mobile-friendly electronic form and a traditional paper-based form. The implementation of the Census was successful, including the effective application of IT during data collection that helped improve the quality of the data and the transparency of the analysis process, ultimately shortening the time it took to publish the recults of Census. The success of the 2019 Census was primarily attributed to the close attention and direction of the Government, Party Committees and authorities at all levels.
