Mother

A convenience reference to the Parent instance whose parental_role is gestational (or, where no gestational parent is recorded, whose certificate_label indicates 'mother'). Retained for compatibility with UN DESA Principles and Recommendations for a Vital Statistics System, Rev 3 (2014), which organizes birth-statistics variables under 'Characteristics of the mother' (Table III.1). Systems that satisfy UN DESA Rev 3 tabulation requirements can derive the 'mother' statistical category by mapping parental_role: gestational to 'mother'. This is a statistical-tabulation helper field, not a modelling assertion that only one parent is a 'mother' or that parenthood is gendered.
