SPLOC is a constructed variable to link the person’s spouse. And if the person does not have a spouse, SPLOC =0. (https://www.atusdata.org/atus-action/variables/SPLOC#description_section)
I’m using SPLOC to link the spouse of ATUS respondents and non-respondents. However, when I created a contingency table of SPLOC and marital status(MARST), I find something looks not right.
As the tables shows, SPLOC gives nearly half of the “Married - spouse present” group value 0. And in some cases in the marital status groups that a person should not have a spouse, SPLOC returns the valid line number. Although the marital status information is collected from the final CPS interview, which takes place 2-5 months before the ATUS interview, it would be too abnormal to conclude that nearly half of the couples get divorced in such a short period.
Meanwhile, another spouse pointer variable ASPOUSE from CPS seems more reliable. There are no cases that tell different story in ASPOUSE variable and MARST variable. (Due to the new user limit, I cannot upload this second image showing the table.)
