In recent COVID-19 epidemic prevention and control work, the population big data platform of Guangzhou's Haizhu district has played a major role. It is the first big data platform in Guangdong province. The district promotes the innovation of urban management methods, management models, and management concepts through the use of big data.

On March 12, Guangzhou issued a notification that a new confirmed COVID-19 case and the person came to Guangzhou from another city. Haizhu immediately implemented graded and classified control measures around the hotel where the person had stayed.

For residents with special needs, Haizhu district relied on the population big data platform to accurately count and locate the information of special groups in the control area, as well as conduct one-to-one contact on time.

The Haizhu population big data platform breaks data barriers, forms a data resource pool with higher accuracy and finer granularity, as well as feeds back to street and community management, establishing a comprehensive theme database and "18+265" grassroots data pools in the whole district.

By building an algorithmic model, the platform visually displays the general profile and dynamic changes of the district's population, directly addressing the inefficiency of street and community management having to rely on paper household registration records to carry out service management. Street and community management personnel visits can complete the approval of basic information, such as personnel and houses, in one visit, providing strong data support for community governance, special actions, as well as scientific decision-making.

The platform breaks the past fundamental problem of insufficient viscosity of data scattered in a single business system. It relies on big data technology to realize the integration and aggregation of relevant information in the jurisdiction on the platform, as well as upgrades the traditional household registration to a digital electronic household registration, which greatly improves work efficiency and meets the refined service management needs of the community.
