Beijing may introduce a new system to allow nonresidents to get a household registration, or hukou, through gaining enough credit points, according to a draft regulation by the Legal Affairs Office of the Beijing Municipal Government.

The move came as the capital stepped up measures to control the size of the population in central areas.

According to a draft regulation released on Thursday for public feedback, criteria for obtaining a hukou include having a Beijing residential permit, being less than 45 years old, having paid social insurance in the capital for at least seven consecutive years and having no criminal record.
