A black household registration refers to a person who has not registered in the household registration management system or whose registration is incomplete. This situation is more common in rural areas, because some farmers may not go to the local police station to register in time, or fail to update their household registration information in time due to family migration, marriage, etc.

People with black household registration may suffer a lot of inconveniences, such as difficulties in applying for credit cards, loans and renting houses. In addition, they face various restrictions on travel, work and employment because they do not have legal identification.

In order to solve the problem of "black household registration", the government has taken many measures, such as canceling the urban household registration of personnel from other units, conducting large-scale household registration survey and registration, promoting household registration transfer, etc. These measures can bring hope to black households, but they will take time and patience. At the same time, we should also improve the household registration awareness of the whole people, update and improve household registration information in a timely manner, and jointly build a healthier, orderly and better society.
