This Bulletin provides information on the numbers and characteristics of two groups of children not frequently recognized in the literature on missing children: those involuntarily missing because they were lost, injured, or stranded and those missing for benign reasons. The estimates reported in this Bulletin are derived from two components of the Second National Incidence Studies of Missing, Abducted, Runaway, and Thrownaway Children (NISMART-2): the National Household Survey of Adult Caretakers and the National Household Survey of Youth. These surveys were conducted during 1999 and reflect the experiences of children in the United States over a 12-month period. Because the vast majority of cases were concentrated in 1999, the annual period the Bulletin refers to is 1999.

On 20 November 2009, the global community celebrates the 20th anniversary of the adoption by the United Nations General Assembly of the Convention on the Rights of the Child, the unique document that sets international standards for the care, treatment and protection of all individuals below age 18. To celebrate this landmark, the United Nations Children's Fund is dedicating a special edition of its flagship report The State of the World's Children to examining the Convention's evolution, progress achieved on child rights, challenges remaining, and actions to be taken to ensure that its promise becomes a reality for all children.

Every day people go missing. Some run away, some are kidnapped, some are the victims of foul play. This book examines true stories of missing persons and their families alongside the various resources available to them.
