Vietnam has a population of more than 99 million people. Population growth has been effectively controlled over the years, with quality being improved in many different ways.

National database on population stores basic information of all Vietnamese citizens which is standardised, digitised, kept and managed by information infrastructure. It is the most important system among the six national databases to help form an e-Government.

Following the first population and housing census in 1979, Vietnam carried out four more censuses in 1989, 1999, 2009 and 2019.
