22,000? I'm not sure what definition they are using of abduction, but children being snatched by strangers is very rare well under 200 cases a year. The DOJ says

An estimated 105 children were victims of stereotypical kidnappings in 2011,

This, of course, is a tiny percentage of the kids listed as missing each year.

According to a 2002 federal study on missing children, 99.8 percent of children reported missing were located or returned home alive. The remaining 0.2 percent either did not return home or were not found. The study estimated that most of missing children cases involved runaways from juvenile facilities and that only an estimated 0.0068 percent were true kidnappings by a stranger. The primary conclusion of the study was that child abductions perpetrated by strangers rarely occur. However, when they do occur, the results can be tragic.
