I plan to use ACS 2010 to determine the degree of exogamy/endogamy of Franco-Americans, overall and stratifying for year of birth and year of marriage. I have looked at various variables and they seem straightforward except one. It seems to me that I could identify couples with the RELATE variable, where 1 is the head of household, and 2 the spouse. What I don’t understand is the SPLOC variable.
I would exclude the households where there is more than one couple, to simplify. Do I then need to use SPLOC, or RELATE would be enough?
