Child Sex Trafficking Data and Response Act of 2013 - Amends part E (Foster Care and Adoption Assistance) of title IV of the Social Security Act to require state plans for foster care and adoption assistance to provide that for each child over whom the state has responsibility for placement, care, or supervision, the state agency shall: (1) identify and document in agency records each child identified as a victim of sex trafficking, including severe forms of trafficking in certain persons; and (2) report immediately, within 24 hours, any information on missing or abducted children to the law enforcement authorities for entry into the National Crime Information Center (NCIC) database of the Federal Bureau of Investigation (FBI).

Requires such plans also to contain a regularly updated description of the specific measures the state agency has taken to protect and provide services to child victims of sex trafficking, including efforts to coordinate with state law enforcement, juvenile justice, and social service agencies such as runaway and homeless youth shelters to serve that population.

Requires the Adoption and Foster Care Analysis and Reporting System (AFCARS) to provide comprehensive national information with respect to the aggregate number of children in foster care identified as victims of sex trafficking.

Amends the Crime Control Act of 1990 to require any law enforcement agency that entered a missing child report into the NCIC to notify the National Center for Missing and Exploited Children of each report received relating to a child reported missing from a foster care family home or childcare institution.

Amends the Child Abuse Prevention and Treatment Act to require that the state plan under the Act certifies that the state has in effect and is enforcing a state law, or is operating a statewide program, relating to child abuse and neglect that includes provisions and procedures requiring: (1) identification and assessment of all reports involving child victims of sex trafficking, and (2) training child protective services workers about identifying and providing comprehensive services for such children.
