I am trying to merge individuals between different years of the March CPS. After 2004 I use the variables
mish sex lineno hrhhid hrhhid2
to merge and it works very well, merging the expected number of infividuals considering the rotation of the panel.
However, when I move back of 2005, the variable hrhhid2 is not available anymore and I cannot find a set of variables that help me to merge let say, march CPS individuals in 2005 to those in 2006, or even 2004 to 2003 data sets.
Is there anyway to merge those series?
