The 2003 Short-Term Co-Resident file is now available. The purpose of the co-resident question series was to collect information on individuals who moved in and out of a Panel Family between the 2001 and 2003 interviewing waves. Information collected about these 397 between-wave co-residents include their move in and out dates and their relationship to the Head of their associated families.
