#' Survey of Youth in Custody, 1987

#' The 1987 Survey of Youth in Custody sampled juveniles and young adults in 
#' long-term, state-operated juvenile institutions. Residents of facilities
#' at the end of 1987 were interviewed about family background, previous

#' survey are contained in the syc data frame.
