When a child is reported missing to law enforcement, federal law requires that child be entered into the FBI's National Crime Information Center, also known as NCIC.
The NCIC recently released its 2019 Missing Person and Unidentified Person statistics. As of December 31, 2019, the NCIC had nearly 87,500 active missing persons records. Youth under the age of 18 account for 35 percent of the records, and 44 percent of the missing persons records are people under 21.
According to the FBI, in 2019 there were 421, 394 NCIC entries for missing children.
