Understanding Society User Support

Hi Emma,
please take a look at table 66 in the Understanding Society Quality Profile. It reports, among other stats, how many women reported to have had a pregancy since the last interview and how many males have reported to have fathered a child since the last interview. The information is collected in the individual response files (_INDRESP). The ennumeration files (_INDALL) furthermore include the variable _NEWMUM and _NEWDAD which assume a value of one if the enumerated person is the biological parent of a new born new entrant to the sample, and the files _NEWBORN include information about new born sample members. Probably best to look at the data so you can compute a newborn indicator using a definition that works for whichever analysis you plan to be doing.
Hope this helps.
Best wishes,
Gundi
