were the MICS maternity questions asked of this sibling?

MICS routes male siblings, and sisters who died before age 12, past the maternity items – so MM22 through MM25 are NA by design for them, not missing data.

Usage

mics_asked_maternity_questions(sib_df)

Arguments

sib_df

the prepped sibling dataset

Value

a logical vector, one entry per row of sib_df

Details

The age test is deliberately "not known to have died under 12" rather than "known to have died at 12 or over". A sister whose age at death was reported as don't-know (MM19 = 98) is set to NA by the prep, and the stricter test silently dropped her even when she had answered MM22–MM24 affirmatively – which is itself proof she was asked. That cost 7 pregnancy-related deaths in Iraq 2018 and 5 in Zimbabwe 2019.
