A total of 249 missing babies have been found to have died, most of them from sickness. But seven were killed and police are investigating their parents.

The Ministry of Health and Welfare is investigating the whereabouts of 2,123 babies whose birth was recorded in hospitals between 2015 and 2022 but who were never registered by their parents.

A notice encouraging people to register births is posted at a district office in Seoul on Monday.

The ministry on Tuesday said provincial governments and the police have found that 1,025 of the unregistered babies are being raised by their parents, relatives, adopted families or in foster care. Another 35 seem never to have existed or were stillborn and appeared in the figures due to administrative errors in hospital.

Of the remaining 814, 601 were abandoned in orphanages.

Police are continuing to investigate parents who deny they ever had a child or claim to have given them up for adoption.
