For Further Information

NISMART Questions and Answers, a fact sheet, offers a straightforward introduction to NISMART–2. It answers anticipated questions—such as What is NISMART? Have abductions by strangers declined or increased? and Why can’t I compare NISMART–1 statistics with NISMART–2 statistics?—to help explain NISMART’s purpose, methodology, and findings.

Other Bulletins in the NISMART series provide more detailed information on the specific types of episodes studied—nonfamily abduction (including stereotypical kidnapping), family abduction, and runaway/thrownaway.
