This research project investigates desired family size and seeks to understand the framing of child numbers in women’s childbearing calculus. Research on childbearing in contextual uncertainties (political, economic and health), suggests that numbers are absent when women express reproductive goals. Thus, the research seeks to explore and understand if there is indeed an absence of child numbers in women’s childbearing calculus due to contextual uncertainties in Mozambique through focus group discussions and semi-structured interviews. The argument put forward by the researcher is that calculus is framed in terms of a minimum number of surviving children (possibly sex specific) and not in terms of a maximum number of children. Once that minimum is attained, the final completed family size is then determined by broader political, economic and health risks.
