Administrative Data. Ideally, administrative data could be accessed through the HMIS system that would provide information on the family background and demographics, service needs, past and ongoing service use, family composition and stability, and family residential arrangements.
Primary Data. Primary data collected through baseline interviews with the families could be used to supplement administrative data if needed. Followup interviews also could be included if administrative data are lacking on key domains such as family stability, residential arrangements, and service use.
