Variable for childless
50%
Description
Hiya,
I'd like to generate a variable that is whether or not an individual is childless (or has had a child) ideally inside or outside the household. I'd really like the variable to be for both USoc/ BHPS. I know that there is a variable in the xwavedat: anychild_dv Ever had a (biological) child - that uses first child's DOB: ch1by_dv First (biological) child birth year
. However given this is part of the xwavedat dataset I wouldn't, for example, be able to use it plot the % of women who are childless as a time series across BHPS and USoc. Would be very grateful for some advice or code that would enable me to construct such a variable that can be used across the two surveys.
Thanks v much in advance,
Charlie

Hello Charlie,
You might want to check variable ch1by_dv, which measures the birth year of the first (biological) child. This variable, together with the interview date variables (intdaty_dv and intdatm_dv), can provide a good approximation for deriving the variable by wave because “ch1by_dv” is also found in xwavedat.
You would just need to define the wave-specific universe for which you want to identify whether respondents had children or not, as the -9 missing values in ch1by_dv also include respondents who were children at the time of the interview.
I hope this information is helpful
Best wishes,
