Ethics approval and consent to participate
: The current study is a secondary analysis of pre-existing, de-identified data and thus was deemed exempt from requiring ethical review by the University of Adelaide Human Research Ethics Committee. Consent to participate was obtained from respondents verbally prior to data collection. Verbal consent was sought as this was the method through which all data were collected from respondents (i.e. enumerators asked respondents a series of questions verbally), and this was aligned with the various ethical and research approvals in each country.
: Not applicable.
: AS and SAB are employed by the World Bank Group outside of the submitted research. The authors declare no other no other competing interests.
