“…Grady et al, 2010;Kusunoki and Upchurch, 2011;Manning et al, 2009;Stolley, 1996), research on the social determinants of contraceptive use has mainly studied the female population, because reproduction and contraception are often framed as a female sphere of influence (Edwards, 1994;Fennell, 2011). Moreover, the majority of studies, also those that have taken men's as well as women's preferences and childbearing desires into account, have limited their attention to individual demographic characteristics, such as the influence of educational attainment or income level on the adoption of certain contraceptive methods (Anderson et al, 2012;Martinez et al, 2006;Moreau et al, 2006;Mosher and Jones, 2010;Oddens et al, 1994aOddens et al, , 1994bSpinelli et al, 2000).…”
