        A Complex Study Design
   The same families have been followed for 34 waves,
    1968-2005
   Initial 1968 sample consisted of two components
      “SRC Sample”: Nationally representative sample of
       ~3,000 families
      “SEO Sample”: ~2,000 low-income families with head
       under
     60 yrs in SMSAs in the North & non-SMSAs in the South
   PSID follows “Split-Offs”
      1968 family members are followed as they grow-up
       and establish own economic family units
      Multiple generations of family members are surveyed
   Significant Changes in 1997
      “Refresher” Sample of immigrants arriving after 1968
