Case file data were included from the three largest providers of runaway services in 2006.
Addresses at baseline were geocoded and linked to census data at the tract level.
There are no gaps in coverage of data with the exception of the runaway shelters where we only have occurrence in 2006 or before.
Although data are collected retrospectively,
exact dates associated with system contacts with the child protection system,
health,
income maintenance,
juvenile justice,
mental health,
runaway shelters,
and special education are used.
