Black households refer to people who have no household registration information, household registration card (resident registration card) and ID card in the national census.

The total population of "black households" is about 654.38+0.3 million, accounting for 654.38+0% of the total population, which has become a major issue affecting social fairness and harmony.

Black households have several reasons:

First, violation of family planning laws and regulations, failure to pay social support fees, unable to register;

Second, there is no information in previous censuses;

Third, in the process of account migration, if you lose your account card, you need to issue a report of loss at the place where you move out, and then reissue your account card at the place where you move in.

The "black households" caused by the lack of household registration information are the most exposed in daily life.
