The  changing  structure of American families can only be tracked if  data a reavailable  to document the c hanges that are occurring. To more accurately  reflect cohabitation and children’ s core sidence with their parents, the Census Bureau improved the way it collects information about two important family  conce pts in the Current Population Survey  (CPS). The first improvement concerns the identification of unmarried partners.  Beginning with the 2007 da ta collec tion of the CPS , a direct question was added to the CPS asking whe ther unmarried adults were living  with a boy friend, g irlfriend or  partner.  The second improvement conce rns the identification of the number a nd type of parents in the household.  A second parent “pointer ”--  which indicate s the presence of  the person’s parent in the household--wa s added to identify whether a child is living with both  their  father and  their  mother.   In addition , th e  type  of  relationship  between the  child and parent, whether biological, step, or adoptive was also obtained as a basic part of  the interview.
