Is the account information of the police station doing real estate statistics legal?

The police station legalizes the household registration information of property statistics

Property companies generally undertake both census and household registration. Some family data are not required by property companies, but by local police stations and other government departments. For example, the Education Bureau requires school-age children to register.

Some data are designed for the privacy of residents. If residents don't want to fill in the data, the property can't be forced. However, statistics on the occupancy of police stations and other government departments may be available later. Secondly, when the owner himself moves in, he needs to provide proof of identity to verify his identity. People who live in the community with the owners should also provide identification. Convenient identity registration.
