According to the National Center for Missing and Exploited Children, roughly 800,000 children are reported missing each year in the United States—that’s roughly 2,000 per day. Of those, there are 115 child “stranger abduction” cases each year, which means the child was taken by an unknown person.

For 2019 it was:
359,768 caucasian.
205, 802 Black.
20,587 unknown.
12,671 Asian.
10,447 Indian (I assume native.)
