dbirth: respondent's date at birth in exact years since January 1, 1900
dint: date at the interview in exact years since January 1, 1900 (March 2004 for all respondents)
d1marr: date at marriage (if any) in exact years since January 1, 1900. If NA, the individual has never been married before the interview.
dch1: date at marriage (if any) in exact years since January 1, 1900. If NA, the individual is childless at the interview.
sex: respondent's sex (factor w/2 levels: "Male", "Female")
edu: respondent's level of education (factor w/3 levels: "low_sec","upp_sec","tert")

Dates in exact years have been computed considering the midpoint of a specific month. Thus, March 1995 means March 15, 1995 and the date in exact years is 95+2.5/12=95.21.
