Following is a response from DHS staff member, Tom Pullum:
When calculating this kind of percentage, or the median age at marriage, you have to assign the never-married women to some numerical value, preferably one that is outside the age range of the data, such as 50 or 99. Otherwise, if they were treated as NA (age at marriage not applicable), the denominator for the calculation will be incorrect. These indicators are tricky to calculate in ever-married samples, because the women who have not (yet) married are not in the data.
