“…The studies also highlight, however, sizeable adjustments of intentions over the life course among other groups. Change over time has been explained by various factors including partnership status (Gray et al, 2013;Hayford, 2009;Iacovou & Tavares, 2011;Liefbroer, 2009;Mitchell & Gray, 2007), education (Dey & Wasoff, 2010;Liefbroer, 2009;Ray et al, 2018), the labour market (Gray et al, 2013;Heiland et al, 2008;Liefbroer, 2009;Ray et al, 2018), religion (Heiland et al, 2008;Ray et al, 2018), number of siblings (Dey & Wasoff, 2010;Heiland et al, 2008) and expectations for more than two children (Quesnel-Vallee & Morgan, 2003). Postponement of childbearing to the thirties, in particular, has been associated with adjustment of intentions downwards over time compared to those who start childbearing earlier (Liefbroer, 2009), as has age more generally, with those in their thirties expecting fewer than those in their twenties (Dey & Wasoff, 2010;Hayford, 2009;Heiland et al, 2008;Quesnel-Vallee & Morgan, 2003).…”
